Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies		Basis of Presentation and Summary of Significant Accounting Policies
		Nature of Operations—Quad/Graphics, Inc. and its subsidiaries (the "Company" or "Quad/Graphics") operates primarily in the commercial print portion of the printing industry as a printer of consumer magazines, catalogs, retail inserts, special interest publications, journals, direct mail, books, directories, in-store marketing, packaging, and other commercial and specialty printed products. The Company also provides media solutions and logistics services for its customers. The Company's products and services are sold primarily throughout the United States, Europe and Latin America to catalogers, publishers and retailers. Additionally, the Company manufactures printing-related auxiliary equipment that is sold to original equipment manufacturers and printing companies throughout the world.
		Principles of Consolidation and Basis of Presentation—The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned controlled subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The results of operations and accounts of businesses acquired are included in the consolidated financial statements from the dates of acquisition (see Note 3, "Acquisitions and Strategic Investments"). Investments in entities where the Company has both the ability to exert significant influence but not control and an ownership interest of 50% or less but more than 20% are accounted for using the equity method of accounting. Investments in entities where the Company does not exert significant influence or control and has an ownership interest of less than 20% are accounted for using the cost method of accounting. Intercompany transactions and balances have been eliminated in consolidation.
		Discontinued Operations—The results of operations of the Company's Canadian operations have been reported as discontinued operations for all periods presented. As the sale of the Canadian operations was completed on March 1, 2012, the corresponding Canadian assets and liabilities are no longer included in the consolidated balance sheets at December 31, 2013 or 2012. In accordance with the authoritative literature, the Company has elected to not separately disclose the cash flows related to the Canadian discontinued operations. See Note 4, "Discontinued Operations," for information about the Company's sale of the Canadian operations.
		Foreign Operations—Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rate existing at the respective balance sheet dates. Income and expense items are translated at the average rates during the respective periods. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of accumulated other comprehensive income (loss) on the consolidated statements of redeemable equity, common stock and other equity and noncontrolling interests while transaction gains and losses are recorded in selling, general and administrative expenses on the consolidated statements of operations. Foreign exchange transactions resulted in gains/(losses) of $(5.7) million, $0.4 million and $(4.5) million for the years ended December 31, 2013, 2012 and 2011, respectively. The Company's international operations are conducted in Europe through Quad/Winkowski Sp. Z o.o. ("Quad/Winkowski"), as well as in the following Latin American countries: Argentina, Brazil, Chile, Colombia, Mexico and Peru. The Company owns 85% of certain operations in Argentina, consolidates those amounts into the Company's consolidated financial statements and presents the 15% not owned by the Company as noncontrolling interest. The Company owns 49% of the operations in Brazil and 50% of the operations in Chile, and accounts for those entities using the equity method of accounting (see Note 11, "Equity Method Investments in Unconsolidated Entities," for further discussion). There are no other significant noncontrolling interests or unconsolidated entities.
		Use of Estimates—The preparation of consolidated financial statements requires the use of management's estimates and assumptions that affect the reported assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. Estimates are used when accounting for items and matters including, but not limited to: allowances for doubtful accounts, inventory obsolescence, asset valuations and useful lives, goodwill, pension and postretirement benefits, self-insurance reserves, stock-based compensation, taxes, restructuring and other provisions and contingencies.
		Revenue Recognition—The Company recognizes its printing revenues upon transfer of title and the passage of risk of loss, which is generally upon shipment to the customer. Under agreements with certain customers, products may be stored by the Company for future delivery. In these situations, the Company may receive warehouse management fees for the services it provides. In certain of these cases, delivery and billing schedules are outlined in the customer agreement and product revenue is recognized when manufacturing is complete, title and risk of loss transfer to the customer, and there is a reasonable assurance as to collectability. Product returns are not significant because the majority of products are customized; however, the Company accrues for the estimated amount of customer allowances at the time of sale based on historical experience and known trends.
		Revenue from services is recognized as services are performed. Revenues related to the Company's imaging operations, which include digital content management, photography, color services and page production, are recognized in accordance with the terms of the contract, typically upon completion of the performed service and acceptance by the customer. Revenues related to the Company's logistics operations, which includes the delivery of printed material, are recognized upon completion of the delivery of services.
		The Company also manufactures printing-related auxiliary equipment to ensure industry-leading technology for its own printing operations, as well as to sell to other businesses. Revenue is generally recognized for the equipment sales at time of shipment. Revenue from services related to the installation of equipment at customer sites are recognized upon completion of the installation. Payments can be received from customers during the manufacture of equipment and prior to shipment or in the case of the installation services prior to completion of the installation. In all cases when payments are received in advance of meeting the applicable revenue recognition criteria, deferred revenue is recorded until the criteria for revenue recognition are subsequently met.
		Services account for greater than 10% of the Company's consolidated net sales; therefore, net sales and related costs of sales of products and services have been included as separate line items in the consolidated statements of operations.
		Certain revenues earned by the Company require judgment to determine if revenue should be recorded gross as a principal or net of related costs as an agent. Billings for third-party shipping and handling costs, primarily in the Company's logistics operations, and out-of-pocket expenses are recorded gross in net sales and cost of sales in the consolidated statements of operations. Many of the Company's operations process materials, primarily paper, that may be supplied directly by customers or may be purchased by the Company and sold to customers. No revenue is recognized for customer-supplied paper. Revenues for Company-supplied paper are recognized on a gross basis.
		Byproduct Recoveries—The Company records the sale of byproducts as net product sales in the consolidated statements of operations.
		Financial Instruments—The Company uses derivative financial instruments for the purpose of hedging commodity and foreign exchange exposures that exist as part of ongoing business operations, including natural gas forward purchase contracts and foreign exchange contracts. As a policy, the Company does not engage in speculative or leveraged transactions, nor does the Company hold or issue financial instruments for trading purposes.
		Derivative instruments are recorded on the consolidated balance sheets as either assets or liabilities measured at their fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged item affects earnings.
		The ineffective portions of the changes in the fair value of hedges are recognized in earnings. Cash flows from derivatives that are accounted for as cash flow or fair value hedges are included in the consolidated statements of cash flows in the same category as the item being hedged.
		Fair Value Measurement—The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities that are required to be recorded at fair value, the Company considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability. See Note 18, "Financial Instruments and Fair Value Measurements," for further discussion.
		Research and Development—Research and development costs related to the development of new products or the adaptation of existing products are expensed as incurred, included in cost of sales and totaled $13.4 million, $13.2 million and $16.9 million during the years ended December 31, 2013, 2012 and 2011, respectively.
		Cash and Cash Equivalents—The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
		Receivables—Receivables are stated net of allowances for doubtful accounts. No single customer comprised more than 5% of the Company's consolidated net sales in 2013, 2012 or 2011 or 5% of the Company's consolidated receivables as of December 31, 2013 or 2012. Specific customer provisions are made when a review of significant outstanding amounts, utilizing information about customer creditworthiness and current economic trends, indicates that collection is doubtful. In addition, provisions are made at differing rates, based upon the age of the receivable and the Company's historical collection experience. See Note 7, "Receivables," for further discussion on the transactions affecting the allowances for doubtful accounts.
		Inventories—Inventories include material, labor, and plant overhead and are stated at the lower of cost or market. At December 31, 2013 and 2012, all inventories were valued using the first-in, first-out ("FIFO") method. See Note 8, "Inventories," for a breakdown of the components of the Company's inventories.
		Property, Plant and Equipment—Property, plant and equipment are recorded at cost, and are depreciated over the estimated useful lives of the assets using the straight-line method for financial reporting purposes. See Note 9, "Property, Plant and Equipment," for a breakdown of the components of the Company's property, plant and equipment. Major improvements that extend the useful lives of existing assets are capitalized and charged to the asset accounts. Repairs and maintenance, which do not significantly improve or extend the useful lives of the respective assets, are expensed as incurred. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective asset.
		Asset Category	Range of Useful Lives
		Buildings	10 to 40 Years
		Machinery and equipment	5 to 15 Years
		Other	3 to 10 Years
		Other Intangible Assets—Identifiable intangible assets are recognized apart from goodwill and are amortized over their estimated useful lives.
		Impairment of Long-Lived and Other Intangible Assets—The Company evaluates long-lived assets and other intangible assets (of which the most significant are property, plant and equipment and customer relationship intangible assets) whenever events and circumstances have occurred that indicate the carrying value of an asset may not be recoverable. Determining whether impairment has occurred typically requires various estimates and assumptions, including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount and the asset's residual value, if any. In turn, measurement of an impairment loss requires a determination of recoverability, which is generally estimated by the ability to recover the balance of the assets from expected future operating cash flows on an undiscounted basis. If impairment is determined to exist, any related impairment loss is calculated based on the difference in the fair value and carrying value of the asset.
		Goodwill—Goodwill is reviewed annually for impairment as of October 31, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. In performing this analysis, the Company compares each reporting unit's fair value estimated based on comparable company market valuations and/or expected future discounted cash flows to be generated by the reporting unit to its carrying value. If the carrying value exceeds the reporting unit's fair value, the Company performs a fair value measurement calculation to determine the impairment loss, which would be charged to operations in the period identified. See Note 6, "Goodwill and Other Intangible Assets," for further discussion.
		Income Taxes—The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of items reported in the financial statements. Under this method, deferred tax assets and liabilities are measured based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the effective date of enactment.
		The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. This determination is based upon all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. If the Company determines that a deferred income tax asset will not be fully realized in the future, then a valuation allowance is established or increased to reflect the amount at which the asset will more likely than not be realized, which would increase the Company's provision for income taxes. In a period after a valuation allowance has been established, if the Company determines the related deferred income tax assets will be realized in the future in excess of their net recorded amount, then an adjustment to reduce the related valuation allowance will be made, which would reduce the Company's provision for income taxes.
		The Company is regularly audited by foreign and domestic tax authorities. These audits occasionally result in proposed assessments where the ultimate resolution might result in the Company owing additional taxes, including in some cases, penalties and interest. The Company recognizes a tax position in its consolidated financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. This recognized tax position is then measured at the largest amount of benefit that is greater than fifty-percent likely of being recognized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense.
		The determination of the Company's worldwide tax provision and related tax assets and liabilities requires the use of significant judgment, estimates, and the interpretation of complex tax laws. In the ordinary course of business, there are transactions and calculations where the final tax outcome is uncertain. While the Company believes it has the appropriate support for the positions taken, certain positions may be successfully challenged by taxing authorities. The Company applies the provisions of the authoritative guidance on accounting for uncertain tax positions to determine the appropriate amount of tax benefits to be recognized with respect to uncertain tax positions. The determination of the Company's worldwide tax provision includes the impact of any changes to the amount of tax benefits recognized with respect to uncertain tax positions. See Note 15, "Income Taxes," for further discussion.
		Pension and Postretirement Plans—The Company assumed certain underfunded defined benefit pension and postretirement benefit plans as part of the 2010 World Color Press acquisition. Pension plan costs are determined using actuarial methods and are funded through contributions. The Company records amounts relating to its pension and postretirement benefit plans based on calculations which include various actuarial assumptions including discount rates, mortality, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. The Company reviews its actuarial assumptions on an annual basis and modifies the assumptions based on current rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the consolidated balance sheets, but are generally amortized into operating income over future periods, with the deferred amount recorded in accumulated other comprehensive income (loss) on the consolidated balance sheets. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. For the purposes of calculating the expected return on plan assets, those assets are valued at fair value. When an event gives rise to both a curtailment and a settlement, the curtailment is accounted for prior to the settlement. The Company's measurement date to measure the defined benefit plan assets and the projected benefit obligation is December 31.
		In addition, as a result of the acquisition of World Color Press, the Company participated in multiemployer pension plans ("MEPPs"). Due to the significant underfunded status of the MEPPs, the Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan, which is historically the form of retirement benefit provided to Quad/Graphics employees. As a result of the decision to withdraw, the Company recorded an estimated withdrawal liability for the MEPPs as part of the purchase price allocation process based on information received from the MEPPs trustees. The estimated withdrawal liability will be updated as new withdrawal liability projections are provided from each plan's trustees until the final withdrawal liability is determined and paid. The exact amount of its withdrawal liability could be higher or lower than the estimate depending on, among other things, the nature and timing of any triggering events and the funded status of the plans at that time. See Note 20, "Employee Retirement Plans," for further discussion.
		Stock-Based Compensation—The Company recognizes stock-based compensation expense over the vesting period for all stock-based awards made to employees and directors based on the fair value of the instrument at the time of grant. See Note 22, "Equity Incentive Programs," for further discussion.
		Accumulated Other Comprehensive Income (Loss)—Accumulated other comprehensive income (loss) consists of unrecognized actuarial gains and losses and prior service costs for pension and postretirement plans and foreign currency translation adjustments and is presented in the consolidated statements of redeemable equity, common stock and other equity and noncontrolling interests. See Note 24, "Accumulated Other Comprehensive Income (Loss)," for further discussion.
		Supplemental Cash Flow Information—Certain supplemental cash flow information related to the Company consists of the following at December 31, 2013, 2012 and 2011:
			2013			2012			2011
		Interest paid, net of amounts capitalized	$	74.2		$	75.5		$	94.4

	The accompanying unaudited condensed consolidated financial statements for Quad/Graphics, Inc. and its subsidiaries (the "Company" or "Quad/Graphics") have been prepared by the Company pursuant to the rules and regulations for interim financial information of the United States Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to such SEC rules and regulations. The results of operations and accounts of businesses acquired are included in the condensed consolidated financial statements from the dates of acquisition (see Note 2, "Acquisitions and Strategic Investments"). These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated annual financial statements as of and for the year ended December 31, 2013, and notes thereto included in the Company's latest Annual Report on Form 10-K filed with the SEC on February 27, 2014.
	The Company is subject to seasonality in its quarterly results as net sales and operating income, when excluding restructuring, impairment and transaction-related charges, are higher in the third and fourth quarters of the calendar year as compared to the first and second quarters. Seasonality is driven by increased magazine advertising page counts, retail inserts, catalogs and books primarily due to back-to-school and holiday related advertising and promotions. The Company expects this seasonality impact to continue in future years.
	The financial information contained herein reflects all normal recurring adjustments, in the opinion of management, necessary for a fair presentation of the Company's results of operations for the three and nine months ended September 30, 2014 and 2013. All intercompany transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements include estimates and assumptions of management that affect the amounts reported in the condensed consolidated financial statements. Actual results could differ from these estimates.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements		New Accounting Pronouncements
		In March 2013, the Financial Accounting Standards Board ("FASB") issued new guidance on the accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or group of assets within a foreign entity or of an investment in a foreign entity. Under this new guidance, the release of cumulative translation adjustments into net income is required when an entity ceases to have a controlling financial interest resulting in the complete or substantially complete liquidation of a subsidiary or group of assets within a foreign entity. This guidance is effective prospectively for fiscal years beginning after December 15, 2013, with early adoption permitted. The Company has adopted this guidance effective January 1, 2013, and determined that it did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.
		In February 2013, the FASB issued new guidance on the disclosure requirements for items reclassified out of accumulated other comprehensive income. Under this new guidance, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The Company adopted this guidance effective January 1, 2013. The adoption of this guidance does not change the current requirements for reporting net income or other comprehensive income, and did not have a material impact on the Company's consolidated financial position, results of operations or cash flows. See Note 24, "Accumulated Other Comprehensive Income (Loss)," for the required disclosure.
New Accounting Pronouncements	New Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board ("FASB") issued new guidance on the required disclosures related to an entity’s ability to continue as a going concern. The guidance requires management to evaluate, at each interim and annual reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued, and provide related disclosures. This guidance is effective for annual periods ending after December 15, 2016, and for each annual and interim period thereafter with early adoption permitted. The Company plans to adopt this new guidance effective December 31, 2016. The Company does not believe the adoption of this guidance will have a material impact on the condensed consolidated financial statements.
	In June 2014, the FASB issued new guidance on certain share-based payment awards, which clarifies the treatment of performance targets that can be met after the requisite service period of a share-based payment award. Under the new guidance, an entity should treat the performance targets that can be met after the requisite period of service as performance conditions that affect vesting. This guidance is effective for interim and annual periods beginning after December 15, 2015 with early adoption permitted. The Company plans to adopt this new guidance effective January 1, 2016. The Company does not believe the adoption of this guidance will have a material impact on the condensed consolidated financial statements.
	In May 2014, the FASB issued new guidance on recognizing revenue from contracts with customers. Under this guidance, an entity will recognize revenue when it transfers promised goods or services to the customer in the amount that reflects what it expects in exchange for the goods or services. This guidance also requires more detailed disclosures to enable users of the financial statements to understand the nature, amount, timing and uncertainty of the revenue and cash flow arising from contracts with customers. This guidance is effective for interim and annual periods beginning after December 15, 2016 with early adoption not permitted. This guidance allows the option of either a full retrospective adoption, meaning the guidance is applied to all periods presented, or a modified retrospective adoption, meaning the guidance is applied only to the most current period. The Company is currently evaluating the impact of this guidance on the condensed consolidated financial statements and determining which transition method to use.
	In April 2014, the FASB issued new guidance on the presentation of discontinued operations, which modifies the requirements for disposals to qualify as discontinued operations and expands related disclosure requirements. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2014, with early adoption permitted for disposals that have not been reported in financial statements previously issued or available for issuance. The Company plans to adopt this new guidance effective January 1, 2015. The adoption of this guidance may impact whether future disposals qualify as discontinued operations and, therefore, could impact the Company’s financial statement presentation and disclosures.

	2014 Brown Printing Company Acquisition												2013 Acquisitions and Strategic Investments
	The Company completed the acquisition of Brown Printing Company ("Brown Printing") on May 30, 2014, for $100.0 million. Brown Printing provides magazine and catalog printing, distribution services and integrated media solutions to magazine publishers and catalog marketers in the United States. The purchase of Brown Printing was accounted for using the acquisition method of accounting under GAAP. The Company recorded the preliminary allocation of the purchase price to the acquired tangible and identifiable intangible assets and liabilities assumed based on their estimated fair values as of the acquisition date. The Company used cash on hand and borrowings under its revolving credit facility to finance the acquisition.												On December 18, 2013, the Company completed the acquisition of Wisconsin-based Proteus Packaging (“Proteus”) as well as its sister company Transpak Corporation (“Transpak”), for $49.1 million. Payments of $43.1 million were made at the close date and the remaining $6.0 million of purchase price represents the Company's current estimate for a deferred payment to be made in 2014 based upon the finalization of the valuation of the net assets. The $6.0 million deferred payment is recorded in accrued liabilities on the consolidated balance sheet.
	Brown Printing's operations are included in the United States Print and Related Services segment. Disclosure of the financial results of Brown Printing since the acquisition date is not practicable as it is not being operated as a standalone business, and has been combined with the Company's existing operations.												Proteus is a designer and manufacturer of high-end paperboard packaging, offering packaging solutions for a wide variety of industries, including automotive, biotechnology, food, personal care, pharmaceuticals, software and electronics. Transpak is a full-service industrial packaging company, offering crating, packaging, warehousing, distribution and logistics services to destinations worldwide.
	The Company recorded a preliminary allocation of the purchase price to tangible and identifiable intangible assets acquired and liabilities assumed, including certain contingent liabilities, based on their fair values as of the May 30, 2014 acquisition date. The preliminary purchase price allocation is as follows:												This acquisition was accounted for using the acquisition method of accounting. The Company recorded the preliminary allocation of the purchase price to the acquired tangible and identifiable intangible assets and liabilities assumed based on their fair values as of the acquisition date. Goodwill resulting from this acquisition, which is deductible for tax purposes, has been recorded within the United States Print and Related Services segment based on the amount by which the purchase price exceeds the fair value of the net assets acquired. The preliminary purchase price allocation is as follows:
		Preliminary Purchase													Preliminary Purchase Price Allocation
		Price Allocation											Accounts receivable		$	4.4
	Cash and cash equivalents	$	3.6
													Other current assets		5.9
	Accounts receivable	46.3
													Property, plant and equipment		13.3
	Other current assets	19.1
													Identifiable intangible assets		24
	Property, plant and equipment	70.8
													Accounts payable and accrued liabilities		(3.7		)
	Identifiable intangible assets	4.7											Other long-term liabilities		(2.8		)
													Goodwill		8
	Other long-term assets	7.5
													Preliminary purchase price		$	49.1
	Accounts payable and accrued liabilities	(35.2		)
	Other long-term liabilities	(16.8		)
	Preliminary purchase price	$	100										The preliminary purchase price allocation is based on valuations performed to determine the fair value of the net assets as of the acquisition date. The valuation of the net assets acquired of $49.1 million was classified as Level 3 in the valuation hierarchy (see Note 18, "Financial Instruments and Fair Value Measurements," for the definition of Level 3 inputs). Identifiable customer relationship intangible assets are amortized on a straight-line basis over six years. The results of operations of the acquired businesses have been included since the acquisition date in the accompanying consolidated financial statements. Pro forma information related to this acquisition is not included because the impact on the Company's consolidated results of operations is considered to be immaterial. Proteus' and Transpak's operations are included in the United States Print and Related Services segment.
													On November 7, 2013, the Company completed the $13.5 million acquisition of Novia CareClinics, LLC ("Novia"), an Indianapolis, Indiana healthcare solutions company. Novia develops and manages onsite and shared primary care clinics for small to medium sized companies and the public sector, such as school districts and city and county governments. Of the $13.5 million purchase price, $13.0 million has been recorded for identifiable customer relationship intangible assets through the preliminary purchase price allocation. Identifiable customer relationship intangible assets are amortized on a straight-line basis over six years. Pro forma information related to this acquisition is not included because the impact on the Company's consolidated results of operations is considered to be immaterial. Novia's operations are included in the United States Print and Related Services segment.
	The preliminary allocation of the purchase price and unaudited pro forma condensed combined financial information is based on valuations performed to determine the fair value of the net assets as of the acquisition date. The final purchase price, as well as the purchase price allocation, is subject to the final determination of acquired working capital and completion of the final valuation of the net assets acquired. The valuation of the net assets acquired of $100.0 million was classified as Level 3 in the valuation hierarchy (see Note 12, "Financial Instruments and Fair Value Measurements," for the definition of Level 3 inputs). Identifiable customer relationship intangible assets are amortized over their estimated useful lives of six years.
													On January 16, 2013, the Company completed the acquisition of substantially all of the assets of Vertis Holdings Inc. (“Vertis”) for $265.4 million, pursuant to the terms of the Asset Purchase Agreement (“Asset Agreement”). Vertis was a leading provider of retail advertising inserts, direct marketing and in-store marketing solutions. The acquisition of Vertis enhanced the Company's position as a leader in the production of retail advertising inserts, direct marketing and in-store marketing solutions that the Company can provide to its clients and enhanced its integrated offerings. The purchase of Vertis was accounted for using the acquisition method of accounting under GAAP. As an asset acquisition, the Company did not acquire certain assets and assume certain liabilities of Vertis and its subsidiaries in the transaction, including, among other liabilities, their underfunded pension and retirement obligations. The Company used cash on hand and borrowings under its revolving credit facility to finance the acquisition.
	2014 Anselmo L. Morvillo S.A. Investment
													In October, 2012, the Company made a $25.9 million deposit to be held in escrow, in accordance with the terms of the Asset Agreement. As of December 31, 2012, the deposit was classified in prepaid expenses and other current assets in the consolidated balance sheets.

Discontinued Operations	Discontinued Operations
	On March 1, 2012, the Company completed the sale of its Canadian operations to Transcontinental (see Note 3, "Acquisitions and Strategic Investments," for a description of the business exchange transaction). Transcontinental assumed pension and post-retirement obligations pertaining to approximately 1,500 Canadian employees, located among the seven facilities sold to Transcontinental. The gain on disposal of discontinued operations, net of tax, was finalized in 2012, and determined as follows:
			As of
			31-Dec-12
	Fair value of the acquired Transcontinental Mexican operations		$	63.6
	Cash paid to Transcontinental		(6.1		)
	Net proceeds		57.5
	Net assets of discontinued operations		(27.2		)
	Cumulative translation adjustment of discontinued operations		3.7
	Gain on disposal of discontinued operations, net of tax(1)		$	34
	______________________________
	-1	For tax purposes the disposal of discontinued operations resulted in a long-term capital loss, for which a deferred tax asset was recorded. An offsetting valuation allowance against the deferred tax asset was recorded to reflect the expected value at which the asset will be recovered.
	As the sale of the Canadian operations was completed on March 1, 2012, there were no results of operations of the Canadian operations for the year ended December 31, 2013. The following table summarizes the results of operations of the Canadian operations, which are included in the loss from discontinued operations in the consolidated statements of operations for the years ended December 31, 2012 and 2011:
			Year Ended December 31,
			2012			2011
	Total net sales		$	32.2		$	343.9
	Loss from discontinued operations before income taxes		(3.2		)	(34.2		)
	Income tax expense		—			4.4
	Loss from discontinued operations, net of tax		$	(3.2	)	$	(38.6	)
	Prior to the March 1, 2012 closing, the Company continued to execute restructuring events related to plant closures, workforce reductions and other restructuring initiatives, as well as transaction costs related to the sale of the Canadian operations. Due to these initiatives, the Company has recognized $1.7 million and $45.1 million in restructuring, impairment and transaction-related costs for the years ended December 31, 2012 and 2011, respectively, within discontinued operations in the consolidated statements of operations. The 2011 restructuring expense included a $17.9 million charge to recognize a pension curtailment loss and a $13.9 million goodwill impairment charge in the third quarter of 2011 for the pending sale of the Canadian discontinued operations due to the carrying value of the Canadian net assets exceeding the estimated fair value of the Mexican net assets acquired from Transcontinental.

	Goodwill is tested annually for impairment as of October 31, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. No indications of impairment were identified during the nine months ended September 30, 2014. Goodwill at September 30, 2014 and December 31, 2013, did not include any accumulated impairment losses. No goodwill impairment was recorded during the three and nine months ended September 30, 2014 or 2013.																					Goodwill is tested annually for impairment as of October 31 or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. The Company completed its annual goodwill impairment assessment of the United States and Latin America reporting units, which included comparing the carrying amount of net assets, including goodwill, of each reporting unit to its respective fair value as of October 31, 2013, the annual assessment date. The European reporting unit does not have goodwill associated with it.
	Activity impacting the Company's goodwill for the nine months ended September 30, 2014, was as follows:																					Fair value was determined using an equal weighting of both the income and market approaches. This fair value determination was categorized as Level 3 in the fair value hierarchy (see Note 18, "Financial Instruments and Fair Value Measurements," for the definition of Level 3 inputs). Under the income approach, the Company determined fair value based on estimated future cash flows discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk and the rate of return an outside investor would expect to earn. Under the market approach, the Company derived the fair value of the reporting units based on market multiples of comparable publicly-traded companies. Management concluded that no impairment existed as of October 31, 2013, because the estimated fair value of each of the Company's United States and Latin America reporting units exceeded the respective carrying amounts. The fair value of the reporting units exceed their respective carrying values by greater than ten percent. No additional indications of impairment have been identified between October 31, 2013, and December 31, 2013.
																						Goodwill at December 31, 2013 and 2012 did not include any accumulated impairment losses. No goodwill impairment was recorded related to continuing operations during the years ended December 31, 2013, 2012 or 2011. However, a $13.9 million goodwill impairment was recorded related to the Canadian discontinued operations in the year ended December 31, 2011 (see Note 4, "Discontinued Operations," for further information).

Quad/Graphics retained ownership of the land and building which are leased to Plural. During the year ended December 31, 2013, the Company recorded a $2.8 million gain on the sale within selling, general and administrative expenses in the Company's consolidated statements of operations. As a result of the sale to Plural, the Company no longer controls these entities (the Company now owns 49% of these entities through its ownership interest in Plural), and thus the assets and liabilities of the entities sold have been deconsolidated in accordance with GAAP. Since the sale to Plural, the Company's ownership interest in the results of operations of these entities are included in equity in earnings (loss) of unconsolidated entities in the consolidated statements of operations.

	The Company continues to manage the bankruptcy claim settlement process for the Quebecor World Inc. ("QWI") bankruptcy proceedings in the United States and Canada (QWI changed its name to "World Color Press Inc." upon emerging from bankruptcy on July 21, 2009). To the extent claims are allowed, the holders of such claims are entitled to receive recovery, with the nature of such recovery dependent upon the type and classification of such claims. In this regard, with respect to certain types of claims, the holders thereof are entitled to receive cash and/or unsecured notes, while the holders of certain other types of claims are entitled to receive a combination of Quad/Graphics common stock and cash, in accordance with the terms of the World Color Press Inc. ("World Color Press") 2010 acquisition agreement.							The Company continues to manage the bankruptcy claim settlement process for the Quebecor World Inc. ("QWI") bankruptcy proceedings in the United States and Canada (QWI changed its name to "World Color Press Inc." upon emerging from bankruptcy on July 21, 2009). To the extent claims are allowed, the holders of such claims are entitled to receive recovery, with the nature of such recovery dependent upon the type and classification of such claims. In this regard, with respect to certain types of claims, the holders thereof are entitled to receive cash and/or unsecured notes, while the holders of certain other types of claims are entitled to receive a combination of Quad/Graphics common stock and cash, in accordance with the terms of the World Color Press acquisition agreement.
	With respect to claims asserted by the holders thereof as being entitled to a priority cash recovery, the Company has estimated that approximately $1.4 million and $2.5 million of such recorded claims have yet to be paid as of September 30, 2014, and December 31, 2013, respectively, and this obligation is classified as amounts owing in satisfaction of bankruptcy claims in the condensed consolidated balance sheets.							With respect to claims asserted by the holders thereof as being entitled to a priority cash recovery, the Company has estimated that approximately $2.5 million and $9.3 million of such recorded claims have yet to be paid as of December 31, 2013, and December 31, 2012, respectively, and this obligation is classified as amounts owing in satisfaction of bankruptcy claims in the consolidated balance sheets.
	With respect to unsecured claims held by creditors of the operating subsidiary debtors of Quebecor World (USA) Inc. (the "Class 3 Claims"), each allowed Class 3 Claim will be entitled to receive an unsecured note in an amount equaling 50% of such creditor's allowed Class 3 Claim, provided, however, that the aggregate principal amount of all such unsecured notes cannot exceed $75.0 million. Each allowed Class 3 Claim will also receive accrued interest and a 5% prepayment redemption premium thereon (the total aggregate maximum principal, interest and prepayment redemption premium for all Class 3 Claims is $89.2 million). In connection with the World Color Press acquisition, the Company was required to deposit the maximum potential payout to the Class 3 Claim creditors of $89.2 million with a trustee, and that amount will remain with the trustee until either (1) it is paid to a creditor for an allowed Class 3 Claim or (2) excess amounts not required for Class 3 Claim payments will revert to the Company.							With respect to unsecured claims held by creditors of the operating subsidiary debtors of Quebecor World (USA) Inc. (the "Class 3 Claims"), each allowed Class 3 Claim will be entitled to receive an unsecured note in an amount not to exceed 50% of such creditor's allowed Class 3 Claim, provided, however, that the aggregate principal amount of all such unsecured notes cannot exceed $75.0 million. In the event that the total of all allowed Class 3 Claims exceeds $150.0 million, each creditor holding an allowed Class 3 Claim will receive its pro rata share of $75.0 million of the unsecured notes issued, together with accrued interest and a 5% prepayment redemption premium thereon (the total of which is $89.2 million). In connection with the World Color Press acquisition, the Company was required to deposit the maximum potential payout to the Class 3 Claim creditors of $89.2 million with a trustee, and that amount will remain with the trustee until either (1) it is paid to a creditor for an allowed Class 3 Claim or (2) upon all Class 3 Claims being resolved any excess amount will revert to the Company. In the year ended December 31, 2013, $4.5 million was paid to Class 3 Claim creditors. At December 31, 2013, $56.0 million remains and is classified as restricted cash in the consolidated balance sheets (see Note 10, "Restricted Cash"). Based on the Company's analysis of the outstanding claims, the Company has a liability of $18.0 million at December 31, 2013, classified as unsecured notes to be issued in the condensed consolidated balance sheets.
	In the nine months ended September 30, 2014, $7.9 million of the restricted cash was paid to Class 3 Claim creditors. The Company received $8.9 million in the nine months ended September 30, 2014, as the restriction was released for amounts no longer required to be held in deposit for Class 3 Claims. At September 30, 2014, $39.2 million of the maximum potential payout to the Class 3 Claim creditors remains and is classified as restricted cash in the condensed consolidated balance sheets. Based on the Company's analysis of the outstanding claims, the Company has a liability of $9.1 million at September 30, 2014, classified as unsecured notes to be issued in the condensed consolidated balance sheets. Activity impacting the Company's restricted cash and unsecured notes to be issued for the nine months ended September 30, 2014, was as follows:
									Restricted Cash			Unsecured Notes to be Issued
								Balance at January 1, 2012	$	75.4		$	38.7
		Restricted Cash			Unsecured
					Notes			Class 3 Claim payments during 2012	(14.9		)	(14.9		)

	Non-cash adjustment	—			(1.0		)
	Balance at September 30, 2014	$	39.2		$	9.1		While the liabilities recorded for any bankruptcy matters are based on management's current assessment of the amount likely to be paid, it is not possible to identify the final amount of priority cash claims or the amount of Class 3 Claims that will ultimately be allowed by the U.S. Bankruptcy Court. Therefore, amounts owing in satisfaction of bankruptcy claims on the consolidated balance sheets could be materially higher than the amounts estimated, which would require additional cash payments to be made for the amount exceeding the Company's estimate. Amounts payable related to the unsecured notes could reach the maximum aggregate principal amount of $75.0 million, which would not require an additional cash payment as the maximum potential exposure has already been funded in trust, but would require additional liability and expense to be recorded as the Company's estimate of total Class 3 Claim liability is $51.2 million ($33.2 million paid plus the $18.0 million remaining estimated liability as of December 31, 2013). In light of the substantial number and amount of claims filed, the claims resolution process will take considerable time to complete.
	The components of the Company's restricted cash at September 30, 2014 and December 31, 2013, were as follows:
		September 30,			December 31,
		2014			2013
	Defeasance of unsecured notes to be issued	$	39.2		$	56
	Other	2.2			—
	Total restricted cash	$	41.4		$	56
	Less: Short-term restricted cash	9.5			4.5
	Long-term restricted cash	$	31.9		$	51.5
	While the liabilities recorded for any bankruptcy matters are based on management's current assessment of the amount likely to be paid, it is not possible to identify the final amount of priority cash claims or the amount of Class 3 Claims that will ultimately be allowed by the U.S. Bankruptcy Court. Therefore, payments for amounts owing in satisfaction of bankruptcy claims could be materially higher than the amounts accrued on the condensed consolidated balance sheets, which would require additional cash payments to be made and expense to be recorded for the amount exceeding the Company's estimate. Amounts payable related to the unsecured notes could exceed current estimates, which would require additional expense to be recorded. In light of the substantial number and amount of claims filed, the claims resolution process will take considerable time to complete.

	The Company records income tax expense on an interim basis. The estimated annual effective income tax rate is adjusted quarterly and items discrete to a specific quarter are reflected in tax expense for that interim period. The effective income tax rate for the interim period can differ from the statutory tax rate, as it reflects changes in valuation allowances due to expected current year earnings or loss and other discrete items, such as changes in the liability for unrecognized tax benefits related to establishment and settlement of income tax exposures.	Income taxes have been based on the following components of earnings from continuing operations before income taxes and equity in earnings (loss) of unconsolidated entities for the years ended December 31, 2013, 2012 and 2011:
	The Company’s liability for unrecognized tax benefits was $34.3 million at September 30, 2014, a decrease of $10.2 million since December 31, 2013, primarily due to the expiration of applicable statutes of limitations. The Company anticipates a decrease to its liability for unrecognized tax benefits of $5.4 million within the next twelve months due to resolution of audits or statute expirations.

		Deferred Income Taxes
		The significant deferred tax assets and liabilities as of December 31, 2013 and 2012, were as follows:
				2013				2012
		Deferred tax assets:
		Accrued liabilities		$	28.9			$	31.4

		______________________________
		-1	As a result of the sale of the Company's two wholly-owned Brazilian subsidiaries as discussed in Note 11, "Equity Method Investments in Unconsolidated Entities," the Company reduced the valuation allowance by $21.3 million (such amount was previously established against the subsidiaries' deferred tax assets that were not expected to be realized).
		The net deferred tax assets (liabilities) above are classified on the consolidated balance sheets at December 31, 2013 and 2012 as follows:
				2013				2012
		Current net deferred tax asset		$	48.1			$	55.7
		Non-current net deferred tax liability		(395.2		)		(363.9		)
		Total		$	(347.1	)		$	(308.2	)
		At December 31, 2013, the Company had foreign net operating loss carry forwards of $141.9 million and state net operating loss carry forwards of $642.3 million. Of the foreign net operating loss carry forwards, $46.6 million are available without expiration, while the remainder expire through 2023. The state net operating loss carry forwards expire in varying amounts through 2033. The Company also has $45.1 million of various state credit carry forwards, of which $30.8 million are available without expiration, while the remainder expire through 2028. At December 31, 2013, the Company has recorded a valuation allowance of $151.5 million against $60.3 million, $41.5 million and $49.7 million of federal, foreign and state deferred tax assets, respectively, that are not expected to be realized.
	On September 13, 2013, the IRS released final tangible property regulations under Sections 162(a) and 263(a) of the Internal Revenue Code and proposed regulations under Section 168 of the Internal Revenue Code. These regulations generally apply to all taxpayers that acquire, produce, or improve tangible property. Based upon preliminary analysis, the Company does not expect that the adoption of these regulations will have a material impact on the consolidated financial statements.
	The Company considers its foreign earnings to be indefinitely invested. Accordingly, the Company does not currently provide for the additional United States and foreign income taxes which would become payable upon remission of undistributed earnings of foreign subsidiaries. The cumulative undistributed earnings of such subsidiaries at December 31, 2013, are not material.
	Uncertain Tax Positions
	The following table summarizes the activity of the Company's liability for unrecognized tax benefits at December 31, 2013, 2012 and 2011:
			2013				2012				2011
	Balance at beginning of period		$	46.5			$	106			$	129.7
	Additions due to acquisitions		—				22.9				0.3
	Additions for tax positions of the current year		0.1				—				—
	Additions for tax positions of prior years		0.7				15.2				5.4
	Reductions for tax positions of prior years		(0.5		)		(76.3		)		(1.4		)
	Settlements during the period		(2.1		)		(7.8		)		(1.4		)
	Lapses of applicable statutes of limitations		(0.2		)		(13.5		)		(1.2		)
	Reclassify Canadian uncertain tax positions to discontinued operations		—				—				(25.4		)
	Balance at end of period		$	44.5			$	46.5			$	106
	As of December 31, 2013, $44.5 million of unrecognized tax benefits would impact the Company's effective tax rate, if recognized. Of that amount, it is reasonably possible that $13.4 million of the total amount of unrecognized tax benefits will decrease within 12 months due to resolution of audits or statute expirations.
	During 2012, the Company settled pre-acquisition World Color Press income tax examinations with the IRS resulting in a net income tax benefit of $30.0 million. Included in this net benefit is $75.7 million related to a reduction for uncertain tax positions of prior years. In addition to the impact on the Company's uncertain tax positions, settlement of the examinations required an adjustment to certain tax attributes of the Company. The impact of the adjustments to these tax attributes resulted in a net income tax expense of $46.7 million.
	The Company classifies interest expense and any related penalties related to income tax uncertainties as a component of income tax expense. The total interest (income) expense related to tax uncertainties recognized in the consolidated statements of operations for the years ended December 31, 2013, 2012 and 2011 was $(1.0) million, $(1.1) million and $(0.7) million, respectively. Penalties in the amount of $(0.2) million, $0 and $(0.1) million were recognized for the years ended December 31, 2013, 2012 and 2011, respectively. Accrued interest of $0.1 million and $2.3 million related to income tax uncertainties was reported as a component of other current liabilities and accrued interest of $4.0 million and $2.8 million related to income tax uncertainties was reported as a component of other long-term liabilities on the consolidated balance sheets at December 31, 2013 and 2012, respectively. There were no accrued penalties related to income tax uncertainties reported in other current liabilities on the consolidated balance sheet at December 31, 2013. Accrued penalties of $0.5 million related to income tax uncertainties were reported in other current liabilities on the consolidated balance sheet at December 31, 2012. Accrued penalties of $0.5 million and $0.4 million related to income tax uncertainties were reported in other long-term liabilities on the consolidated balance sheets at December 31, 2013 and 2012, respectively.
	The Company has tax years from 2010 through 2013 that remain open and subject to examination by the IRS. Tax years from 2003 through 2013 remain open and subject to examination in the Company's various major state jurisdictions within the United States.

								-2	On July 26, 2011, and as last amended on December 19, 2012, the Company entered into a $1.5 billion debt financing agreement with certain lenders to reduce the Company's borrowing costs with lower interest rates and to create more flexibility with a higher revolving credit capacity and improvement in financial terms. The $1.5 billion debt financing agreement includes three different loan facilities, a Term Loan A, a Term Loan B, and a revolving credit facility.

	Long-term debt	$	1,505.80		$	1,265.70		The revolving credit facility in the amount of $850.0 million and the Term Loan A in the aggregate amount of $450.0 million each had an initial term of five years that was extended an additional year as part of the December 19, 2012 amendment to mature on July 25, 2017. The Term Loan B in the amount of $200.0 million (net of a $1.0 million original issue discount) has a term of seven years maturing on July 25, 2018, subject to certain required amortization.
								Borrowings under the revolving facility and Term Loan A loans made under the $1.5 billion debt financing agreement bear interest at London Interbank Offered Rate ("LIBOR") plus 2.25%, or 1.25% in excess of an alternate base rate, and Term Loan B loans bear interest at LIBOR plus 3.00%, with a LIBOR floor of 1.00%, or 2.00% in excess of an alternative base rate at the Company's option. At December 31, 2013, the Company had borrowings of $209.8 million on the revolving credit agreement, as well as $44.0 million of issued letters of credit, leaving $596.2 million available for future borrowings.
	Fair Value of Debt
								The proceeds from the Term Loan A, Term Loan B and revolving credit facility were used to repay all outstanding balances and terminate the Company's previous $1.23 billion debt financing agreement (which included the $700.0 million term loan and the $530.0 million revolving credit facility), as well as to pay the new debt issuance costs incurred for the refinancing. The $1.5 billion debt financing agreement is secured by substantially all of the assets in the United States that are not encumbered under the Company's other financing agreements.
	Based upon the interest rates available to the Company for borrowings with similar terms and maturities, the fair value of the Company's total debt was approximately $1.6 billion and $1.4 billion at September 30, 2014 and December 31, 2013, respectively. The fair value determination of the Company's total debt was categorized as Level 2 in the fair value hierarchy (see Note 12, "Financial Instruments and Fair Value Measurements," for the definition of Level 2 inputs).
								The Company recognized a $34.0 million loss on debt extinguishment during the year ended December 31, 2011, in connection with the July 26, 2011 $1.5 billion debt financing agreement. The loss was comprised of: (1) $20.9 million of debt issuance costs from the terminated $1.23 billion debt financing agreement, (2) $8.9 million of remaining original issue discount from the terminated $1.23 billion debt financing agreement and (3) $4.2 million of debt issuance costs from the $1.5 billion debt financing agreement. The $34.0 million loss was classified as loss on debt extinguishment in the consolidated statements of operations.
	$1.9 Billion Debt Financing Arrangements
	The Company completed its $1.9 billion debt financing arrangements on April 28, 2014, which included refinancing, extending and expanding its existing revolving credit facility, Term Loan A and Term Loan B with a $1.6 billion senior secured credit facility (the “Senior Secured Credit Facility”) and an offering of $300 million aggregate principal amount of its unsecured 7.0% senior notes due May 1, 2022 (the “Senior Unsecured Notes”). The Senior Secured Credit Facility and the Senior Unsecured Notes were entered into to extend and stagger the Company’s debt maturity profile, further diversify its capital structure and provide more borrowing capacity to better position the Company to execute on its strategic goals. The proceeds from the Senior Secured Credit Facility and Senior Unsecured Notes were used to: (1) repay the Company’s previous revolving credit facility, Term Loan A, Term Loan B and the international term loan, (2) fund the acquisition of Brown Printing and (3) for general corporate purposes.							-3	On December 16, 2008, debt related to the Company's international operations was refinanced by entering into a secured credit agreement ("Facilities Agreement"). The Facilities Agreement includes a Euro denominated term loan and a multicurrency revolving credit facility. The term loan principal payments commenced in December 2009 and it matures on December 16, 2015. The multicurrency revolving credit facility used for financing working capital and general business needs, was renewed in 2013 and will expire on December 16, 2014. At December 31, 2013, the Company's international operations had borrowings of $2.3 million under the multicurrency revolving credit facility, leaving $14.3 million available for future borrowing. The terms of the Facilities Agreement include certain financial covenants, a guarantee of the Facilities Agreement by the Company and a security agreement that includes collateralizing substantially all of the Quad/Winkowski assets. The facilities bear interest at the aggregate of the Warsaw Interbank Offered Rate ("WIBOR") or the Euro Interbank Offered Rate ("EURIBOR") and margin.
	Senior Secured Credit Facility
								-4	During 2013, the Company refinanced certain equipment leases with $17.1 million in equipment term loans secured by the formerly leased equipment. The equipment term loans bear interest at a fixed rate of 4.75%, require quarterly payments and have five year terms expiring during 2018. The purchase of these assets resulted in $12.8 million of non-cash investing and financing activities, which represents the $17.1 million in equipment term loans net of $4.3 million of eliminated capital lease obligations (see Note 1, "Basis of Presentation and Summary of Significant Accounting Policies").
	The Senior Secured Credit Facility consists of three different loan facilities. The first facility is a revolving credit facility in the amount of $850.0 million with a term of five years maturing on April 27, 2019. The second facility is a Term Loan A in the aggregate amount of $450.0 million with a term of five years maturing on April 27, 2019, subject to certain required amortization. The third facility is a Term Loan B in the amount of $300.0 million with a term of seven years maturing on April 27, 2021, subject to certain required amortization.
								Based upon the interest rates available to the Company for borrowings with similar terms and maturities, the fair value of the Company's total debt was approximately $1.4 billion and $1.3 billion at December 31, 2013 and 2012, respectively. The fair value determination of the Company's total debt was categorized as Level 2 in the fair value hierarchy (see Note 18, "Financial Instruments and Fair Value Measurements," for the definition of Level 2 inputs). As of December 31, 2013, approximately $3.0 billion of the Company's assets were pledged as security under various loans and other agreements.
	Borrowings under the revolving credit facility and Term Loan A loans made under the Senior Secured Credit Facility will initially bear interest at 2.00% in excess of reserve adjusted London Interbank Offered Rate ("LIBOR"), or 1.00% in excess of an alternate base rate, and Term Loan B loans will bear interest at 3.25% in excess of reserve adjusted LIBOR, with a LIBOR floor of 1.00%, or 2.25% in excess of an alternative base rate at the Company's option.
								Debt Issuance Costs
	The Senior Secured Credit Facility is secured by substantially all of the unencumbered assets of the Company. The Senior Secured Credit Facility also requires the Company to provide additional collateral to the lenders in certain limited circumstances.
								Activity impacting the Company's debt issuance costs for the years ended December 31, 2013, and 2012, was as follows:
	Senior Unsecured Notes
	The Company received $294.8 million in net proceeds from the sale of the Senior Unsecured Notes, after deducting the initial purchasers’ discounts and commissions.

	Debt Issuance Costs and Original Issue Discount							______________________________
	The Company incurred $14.3 million in debt issuance costs in conjunction with the $1.9 billion debt financing arrangement completed on April 28, 2014. In accordance with the accounting guidance for the treatment of debt issuance costs in a debt extinguishment, of the $14.3 million in new debt issuance costs, $11.0 million was capitalized and is classified as other long-term assets in the condensed consolidated balance sheets and $3.3 million was expensed and is classified as loss on debt extinguishment in the condensed consolidated statements of operations. In addition, a new original issue discount of $3.0 million related to Term Loan B of the Senior Secured Credit Facility was classified as a reduction of long-term debt in the condensed consolidated balance sheets.							-1	The Company incurred $2.1 million of debt issuance costs in connection with the December 19, 2012, $1.5 billion debt financing agreement amendment for the extension of the maturity dates on the $850.0 million revolving credit facility and the $450.0 million Term Loan A.

	The Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan. The two MEPPs, the Graphic Communications International Union – Employer Retirement Fund (“GCIU”) and the Graphic Communications Conference of the International Brotherhood of Teamsters National Pension Fund (“GCC”), are significantly underfunded, and will require the Company to pay a withdrawal liability to fund its pro rata share of the underfunding as of the plan year the full withdrawal was completed. As a result of the decision to withdraw, the Company accrued a $98.6 million estimated withdrawal liability based on information provided by each plan's trustee, as part of the purchase price allocation for World Color Press.

	The Company has received notices of withdrawal and demand for payment letters for both the GCIU and GCC plans, which, in total are in excess of the $98.6 million in original reserves established by the Company for the withdrawals. The Company is in the process of determining the final withdrawal payment, and is currently in arbitration with the MEPPs' trustees and arbitrators have been selected. The withdrawal liability reserved by the Company is within the range of the Company's estimated potential outcomes. The Company made payments totaling $10.8 million for the nine months ended September 30, 2014 and 2013, respectively, as requested by the MEPPs and as required by the Employee Retirement Income Security Act, although such payments do not waive the Company's rights to object to the withdrawal liabilities submitted by the GCIU and GCC plan administrators.

														In 2013, the Company paid out lump sums to participants that exceeded the threshold for settlement accounting, which resulted in an acceleration of the recognition of accumulated other comprehensive income and a settlement gain of $2.1 million. The settlement gain was recorded in restructuring, impairment and transaction-related charges in the consolidated statement of operations.
														In 2012, the Company announced the elimination of life insurance coverage for all current and future retirees in all locations and the elimination of reimbursement of medical costs for certain retirees, which resulted in the reduction of plan obligations by $5.7 million. In addition, the Company also announced the elimination of postretirement medical benefit coverage for all future retirees who will retire after December 31, 2012, which resulted in the reduction of plan obligations by $16.9 million and recognition of a curtailment gain of $12.8 million. The curtailment gain was recorded in restructuring, impairment and transaction-related charges in the consolidated statement of operations.
													Actuarial gains and losses in excess of 10% of the greater of the projected benefit obligation or the market-related value of plan assets are recognized as a component of net periodic benefit costs over the average remaining service period of a plan's active employees. Unrecognized prior service costs or credit are also recognized as a component of net periodic benefit cost over the average remaining service period of a plan's active employees. The amounts in accumulated other comprehensive income (loss) that are expected to be recognized as components of net periodic pension and postretirement benefit expense (income) over the next year are as follows:
															Pension Expense (Income)				Postretirement Expense (Income)

													Plan Assets and Investment Strategy
													The Company follows a disciplined investment strategy, which provides diversification of investments by asset class, foreign currency, sector and company. The Pension Committee has approved investment policies for the different pension plans that establish long-term asset mix targets based on several factors including: historical returns achieved by worldwide investment markets, the time horizon of the pension plans' obligations and the investment risk. For each of the plans, an allocation range by asset class is developed whereby a mix of equities and fixed-income investments is used to provide an appropriate risk-adjusted long-term return on plan assets. Third-party investment managers are employed to invest assets in both passively-indexed and actively-managed strategies and investment returns and risks are monitored on an ongoing basis. Derivatives are used at certain times to hedge foreign currency exposure. Gains or losses on the derivatives are offset by a corresponding change in the value of the hedged assets. Derivatives are strictly used for hedging purposes and not speculative purposes.
													The target allocations for plan assets on a weighted-average basis are 65% equity securities and 35% fixed-income, including cash and cash equivalents. The actual asset allocation as of December 31, 2013, was approximately 67% equity securities and 33% debt securities. The actual asset allocation as of December 31, 2012, was approximately 64% equity securities, 35% debt securities and 1% other. Equity investments are diversified by country, issuer and industry sector. Fixed income securities primarily consist of government bonds and corporate bonds from diversified industries.
													The expected long-term rate of return on assets assumption is selected by first identifying the expected range of long-term rates of return for each major asset class. Expected long-term rates of return are developed based on long-term historical averages, current expectations of future returns and anticipated inflation rates. The expected long-term rate of return on plan assets is then calculated by weighting each asset class. To the extent that individual pension plans have different target asset mixes, the expected long-term rate of return on assets may differ across plans.
													The fair values of the Company's pension plan assets at December 31, 2013 and 2012 by asset category are as follows:
															December 31, 2013															December 31, 2012
													Asset Category		Total				Level 1				Level 2			Level 3				Total			Level 1			Level 2		Level 3
													Cash and cash equivalents		$	0.3			$	0.3			$	—		$	—			$	0.4		$	0.4		$	—	$	—
													Fixed income		171.5				—				171.5			—				162.1			—			162.1		—
													Equities		353.4				122.9				230.5			—				295			270.8			24.2		—

													Total		$	525.2			$	123.2			$	402		$	—			$	458.9		$	271.2		$	187.7	$	—
													There are no Level 3 assets or liabilities as of December 31, 2013 and 2012.
													The Company segregated its plan assets by the following major categories and levels for determining their fair value as of December 31, 2013:
													Cash and cash equivalents. Carrying value approximates fair value and these assets are classified as Level 1.
													Fixed Income. This category consists of bonds and short-term fixed income securities fair valued based on a compilation of primarily observable market information or broker quotes in over-the-counter markets and are classified as Level 2.
													Equities. This category consists of equity investments and equity pooled funds and these assets are classified as Level 1 and Level 2, respectively. The fair value of equity investments is based on quoted prices in an active market. The fair value of the equity pooled funds is based on the funds' Net Asset Value ("NAV") established by the funds' administrator.
													The valuation methodologies described above may generate a fair value calculation that may not be indicative of net realizable value or future fair values. While the Company believes the valuation methodologies used are appropriate, the use of different methodologies or assumptions in calculating fair value could result in different amounts. The Company invests in various assets in which valuation is determined by NAV. The Company believes that NAV is representative of fair value at the reporting date, as there are no significant restrictions on redemption on these investments or other reasons to indicate that the investment would be redeemed at an amount different than NAV.
													Risk Management
													For all directly invested funds, the concentration risk is monitored through specific guidelines in the investment manager mandates. The investment manager mandates were developed by the Company's external investment advisor, and specify diversification standards such as the maximum exposure per issuer, and concentration limits per type of security, industry and country when applicable.
													For the investments made through pooled funds, the investment mandates of the funds were again reviewed by the Company's external investment advisor, to determine that the investment objectives and guidelines were consistent with the Company's overall pension plan risk management objectives. In managing the plan assets, management reviews and manages risk associated with funded status risk, interest rate risk, market risk, counterparty risk, liquidity risk and operational risk. Liability management and asset class diversification are central to the Company's risk management approach and are integral to the overall investment strategy.
													Given the process in place to ensure a proper diversification of the portfolio, management believes that the Company pension plan assets are not exposed to significant concentration risk.
													Multiemployer Pension Plans
													The Company participates in a number of MEPPs under terms of collective bargaining agreements that cover a number of its employees. The risks of participating in these MEPPs are different from single employer plans in the following aspects:
													•	Assets contributed to the MEPPs by one company may be used to provide benefits to employees of other participating companies.
													•	If a participating company stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating companies.
													•	If the Company stops participating in some or all of its MEPPs, and continues in business, the Company would be required to pay an amount, referred to as a withdrawal liability, based on the unfunded status of the plan.
													The Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan. The two MEPPs, the Graphic Communications International Union - Employer Retirement Fund (“GCIU”) and the Graphic Communications Conference of the International Brotherhood of Teamsters National Pension Fund (“GCC”), are significantly underfunded, and will require the Company to pay a withdrawal liability to fund its pro rata share of the underfunding as of the plan year the full withdrawal was completed. As a result of the decision to withdraw, the Company accrued a $98.6 million estimated withdrawal liability based on information provided by each plan's trustee, as part of the purchase price allocation for World Color Press. The Company is making required interim payments to the MEPPs for the Company's withdrawal liability from the GCIU and the GCC plans.
													The GCIU Plan is a defined benefit plan that provides retirement benefits, total and permanent disability benefits, and pre-retirement death benefits for the participating union employees of the Company. The funded status of the GCIU Plan is classified as critical based on the GCIU Plan's 2013 certification to the United States Department of Labor, as the funded percentage for the plan is less than 65% and is projected to have an accumulated funding deficit over the next four plan years. As a result, the GCIU Plan implemented a rehabilitation plan to improve the plan's funded status. The Company estimates that contributions made to the GCIU Plan by the Company represent greater than 5% of total contributions made by all participating employers in the 2012 plan year (the plan year ended December 31, 2012, is the latest available financial information provided by the GCIU Plan).
													The GCC Plan is a defined benefit plan that provides retirement benefits, disability benefits, and early retirement benefits for the participating union employees of the Company. The funded status of the GCC Plan is classified as critical based on the GCC Plan's 2013 certification to the United States Department of Labor, as the funded percentage for the plan is less than 65% and is projected to have an accumulated funding deficit over the next four plan years. As a result, the GCC Plan implemented a rehabilitation plan to improve the plan's funded status. The Company estimates that contributions made to the GCC Plan by the Company represent greater than 5% of total contributions made by all participating employers in the 2011 plan year (the plan year ended April 30, 2012, is the latest available financial information provided by the GCC Plan).
													The Company has received notices of withdrawal and demand for payment letters for both the GCIU and GCC plans, which, in total are in excess of the $98.6 million in original reserves established by the Company for the withdrawals. The Company is in the process of determining the final withdrawal payment with both MEPPs' administrators, and the withdrawal liability reserved by the Company is within the range of the Company's estimated potential outcomes. During this process the Company began making monthly payments totaling $14.4 million and $11.2 million for the years ended December 31, 2013 and 2012, respectively, as requested by the MEPPs and as required by the Employee Retirement Income Security Act, although such payments do not waive the Company's rights to object to the withdrawal liabilities submitted by the GCIU and GCC plan administrators. As of December 31, 2013, the Company has reserved $73.0 million as its estimate of the total MEPPs withdrawal liability, of which $53.1 million is recorded in other long-term liabilities, $14.4 million is recorded in accrued liabilities and $5.5 million is recorded in unsecured notes to be issued in the consolidated balance sheets. This estimate may increase or decrease depending on the final agreement with the MEPPs' administrators.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share Attributable to Quad/Graphics Common Shareholders	Earnings (Loss) Per Share Attributable to Quad/Graphics Common Shareholders													Earnings (Loss) Per Share Attributable to Quad/Graphics Common Shareholders
	Basic earnings (loss) per share attributable to Quad/Graphics common shareholders is computed as net earnings (loss) attributable to Quad/Graphics common shareholders less the allocation of participating securities, divided by the basic weighted average common shares outstanding of 47.5 million and 47.4 million shares for the three and nine months ended September 30, 2014, respectively, and 47.0 million and 46.9 million shares for the three and nine months ended September 30, 2013, respectively. The calculation of diluted earnings per share includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of (1) the amount the employee must pay upon exercise of the award, (2) the amount of unearned stock-based compensation costs attributed to future services and (3) the amount of tax benefits, if any, that would be credited to additional paid-in capital assuming exercise of the award. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net losses, and accordingly, the Company excludes them from the calculation. Due to the net loss attributable to Quad/Graphics common shareholders incurred during the nine months ended September 30, 2014 and 2013, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, not included in the diluted loss per share attributable to Quad/Graphics common shareholders calculation for those periods. Anti-dilutive equity instruments of 2.0 million and 2.9 million of class A common shares were excluded from the computation of diluted net earnings (loss) per share for the three and nine months ended September 30, 2014, respectively. Anti-dilutive equity instruments of 0.8 million and 2.8 million of class A common shares were excluded from the computation of diluted net earnings (loss) per share for the three and nine months ended September 30, 2013, respectively. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are required to be treated as participating securities and included in the computation of earnings (loss) per share pursuant to the two-class method. The Company's participating securities are composed of unvested stock options granted on November 18, 2011. The Company's participating securities had no impact on basic and diluted earnings per share attributable to Quad/Graphics common shareholders for the three months ended September 30, 2014, and increased basic and diluted loss per share attributable to Quad/Graphics common shareholders by $0.01 for the nine months ended September 30, 2014. The Company's participating securities decreased basic and diluted earnings per share attributable to Quad/Graphics common shareholders by $0.01 for the three months ended September 30, 2013, and increased basic and diluted loss per share attributable to Quad/Graphics common shareholders by $0.02 for the nine months ended September 30, 2013.													Basic earnings (loss) per share attributable to Quad/Graphics common shareholders is computed as net earnings (loss) attributable to Quad/Graphics common shareholders less the allocation of participating securities, divided by the basic weighted average common shares outstanding of 47.0 million, 46.8 million and 47.1 million shares for the years ended December 31, 2013, 2012 and 2011, respectively. The calculation of a diluted earnings per share amount includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of (1) the amount the employee must pay upon exercise of the award, (2) the amount of unearned stock-based compensation costs attributed to future services and (3) the amount of tax benefits, if any, that would be credited to additional paid-in capital assuming exercise of the award. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net earnings from continuing operations, and accordingly, the Company excludes them from the calculation. Anti-dilutive equity incentive instruments of 1.6 million and 3.2 million of class A common shares were excluded from the computations of diluted net earnings per share for the years ended December 31, 2013 and 2012, respectively. Due to the net loss from continuing operations attributable to Quad/Graphics common shareholders incurred during the year ended December 31, 2011, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, not included in the diluted loss per share attributable to Quad/Graphics common shareholders calculation for that period.
	Reconciliations of the numerator and the denominator of the basic and diluted per share computations for the Company's common stock, for the three and nine months ended September 30, 2014 and 2013, are summarized as follows:													Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are required to be treated as participating securities and included in the computation of earnings (loss) per share pursuant to the two-class method. The Company's participating securities are composed of unvested stock options granted on November 18, 2011, and reduced basic and diluted earnings per share attributable to Quad/Graphics common shareholders by $0.02 and $0.07 per diluted share for the years ended December 31, 2013 and 2012, respectively. There was no impact to basic and diluted earnings per share attributable to Quad/Graphics common shareholders during 2011.

As of September 30, 2014, there are 1,771,669 shares available for issuance under the Omnibus Plan.													The shareholders of the Company approved the Quad/Graphics Inc. 2010 Omnibus Incentive Plan ("Omnibus Plan") for two complimentary purposes: (1) to attract and retain outstanding individuals to serve as directors, officers and employees and (2) to increase shareholder value. The Omnibus Plan replaced the 1999 Nonqualified Stock Option Plan and the 1990 Stock Option Plan and, as of January 1, 2011, all equity grants are made from the Omnibus Plan. In May 2012 and 2013, an additional 3,571,652 and 2,000,000 shares, respectively, were approved for issuance under the Omnibus Plan, making 7,871,652 shares of Class A stock reserved for issuance under the Omnibus Plan. Awards under the Omnibus Plan may consist of incentive awards, stock options, stock appreciation rights, performance shares, performance share units, shares of class A stock, restricted stock, restricted stock units, deferred stock units or other stock-based awards as determined by the Company's board of directors. Each stock option granted has an exercise price of no less than 100% of the fair market value of the class A stock on the date of grant. As of December 31, 2013, there are 2,400,763 shares available for issuance under the Omnibus Plan.
	The Company recognizes compensation expense, based on estimated grant date fair values, for all share-based awards issued to employees and non-employee directors, including stock options, performance shares, performance share units, restricted stock, restricted stock units and deferred stock units. The Company recognizes these compensation costs for only those awards expected to vest, on a straight-line basis over the requisite three to four year service period of the awards, except deferred stock units, which are fully vested and expensed on the grant date. The Company estimated the number of awards expected to vest based, in part, on historical forfeiture rates and also based on management's expectations of employee turnover within the specific employee groups receiving each type of award. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods, if actual forfeitures differ from those estimates.

	Net tax expense on equity award activity, shown as tax (expense) benefit on equity award activity in the financing section of the condensed consolidated statements of cash flows, was $0.9 million during the nine months ended September 30, 2014. There were $0.5 million net tax benefits on equity award activity during the nine months ended September 30, 2013.													Stock Options
	Stock Options													On November 18, 2011, the Company announced that the Board of Directors had approved the termination of the outstanding stock options under the Company's 1990 Stock Option Plan and 1999 Nonqualified Stock Option Plan (the “409A Options”). In accordance with the authoritative literature for the termination and modification of stock options, as of December 31, 2011, the Company recorded a $20.0 million liability for the termination payment, which was based on the number of 409A Options held by the option holders, the Company's weighted volume adjusted stock price of $13.47 as of November 18, 2011, and the exercise price of the 409A Options. The termination payment was paid in December 2012. In addition, in 2011, the Company recorded $6.4 million of incremental stock option expense, which is recorded in restructuring, impairment and transaction-related charges in the consolidated statements of operations.
	Options vest over four years, with no vesting in the first year, and one-third vesting upon the second, third and fourth anniversary dates. As defined in the individual grant agreements, acceleration of vesting may occur under a change in control, death, disability or normal retirement of the grantee. Options expire no later than the tenth anniversary of the grant date, 24 months after termination for death, 36 months after termination for normal retirement or disability and 90 days after termination of employment for any other reason. Options are not credited with dividend declarations, except for the November 18, 2011 grants. Stock options are only to be granted to employees.													The option holders were granted new options under the Omnibus Plan equal to the number of terminated 409A Options held by them. All of the new options were granted at an exercise price equal to or greater than the fair market value of $13.47 per share, and if the exercise price of an option holders' 409A Options was greater than $13.47, then the new options were issued at such greater price. Therefore, none of the new options were granted with an exercise price below fair market value and all of the new options were granted at an exercise price equal to or greater than the corresponding 409A Option that was canceled.
	There were no stock options granted under the Omnibus Plan during the three and nine months ended September 30, 2014 and 2013. Compensation expense recognized related to stock options was $2.0 million and $6.0 million for the three and nine months ended September 30, 2014, respectively, and $2.3 million and $7.1 million for the three and nine months ended September 30, 2013, respectively. Total future compensation expense for all stock options granted as of September 30, 2014, is approximately $1.5 million. Estimated future compensation expense is $1.3 million for 2014 and $0.2 million for 2015.													For new option grants beginning January 1, 2011, options vest over four years, with no vesting in the first year and one-third vesting upon the second, third and fourth anniversary dates. As defined in the individual grant agreements, acceleration of vesting may occur under a change in control, death, disability or normal retirement of the grantee. For the new option grants beginning January 1, 2011, options expire no later than the tenth anniversary of the grant date, twenty-four months after termination for death, thirty-six months after termination for normal retirement or disability and 90 days after termination of employment for any other reason. While stock options granted prior to 2011 were credited with dividend declarations, the new option grants after that time are not credited with dividend declarations, excluding the November 18, 2011 grants. Stock options are only to be granted to employees and will only be granted under the new option grant terms from January 1, 2011 forward.
	The following table is a summary of the stock option activity for the nine months ended September 30, 2014:													There were no stock options granted under the Omnibus plan during the year ended December 31, 2013. There were 448,154 stock options granted with a grant date weighted average fair value of $2.25 during the year ended December 31, 2012. There were 451,029 stock options granted with a grant date weighted average fair value of $13.17 during the year ended December 31, 2011. Excluding the 3,571,652 new options granted on November 18, 2011, the fair market value of stock options is determined using the Black-Scholes-Merton option pricing module. The fair market value of the stock options is determined using the following weighted average assumptions for the years ended December 31, 2012 and 2011:
		Shares Under		Weighted Average			Weighted Average		Aggregate							2012			2011
		Option		Exercise			Remaining		Intrinsic Value					Expected volatility		36.7	%		36	%

														The Company determined expected volatility based on the volatility of comparable company stock. The average risk-free interest rate is based on the United States treasury security rate in effect as of the grant date over the term of the expected life. The expected life is based on the term and vesting period of each grant adjusted for historical experience in vesting.

During the year ended December 31, 2012, the balance of redeemable equity decreased by $3.5 million as a result of the conversion of all outstanding class C common shares into class A common shares. As such, information regarding the changes in redeemable equity for the years ended December 31, 2012 and 2011 is provided in the table below:

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended		12 Months Ended
	Sep. 30, 2014		Dec. 31, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation and Basis of Presentation			Principles of Consolidation and Basis of Presentation—The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned controlled subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The results of operations and accounts of businesses acquired are included in the consolidated financial statements from the dates of acquisition (see Note 3, "Acquisitions and Strategic Investments"). Investments in entities where the Company has both the ability to exert significant influence but not control and an ownership interest of 50% or less but more than 20% are accounted for using the equity method of accounting. Investments in entities where the Company does not exert significant influence or control and has an ownership interest of less than 20% are accounted for using the cost method of accounting. Intercompany transactions and balances have been eliminated in consolidation.
Discontinued Operations			Discontinued Operations—The results of operations of the Company's Canadian operations have been reported as discontinued operations for all periods presented.
Foreign Operations			Foreign Operations—Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rate existing at the respective balance sheet dates. Income and expense items are translated at the average rates during the respective periods. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of accumulated other comprehensive income (loss) on the consolidated statements of redeemable equity, common stock and other equity and noncontrolling interests while transaction gains and losses are recorded in selling, general and administrative expenses on the consolidated statements of operations.
Use of Estimates			Use of Estimates—The preparation of consolidated financial statements requires the use of management's estimates and assumptions that affect the reported assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. Estimates are used when accounting for items and matters including, but not limited to: allowances for doubtful accounts, inventory obsolescence, asset valuations and useful lives, goodwill, pension and postretirement benefits, self-insurance reserves, stock-based compensation, taxes, restructuring and other provisions and contingencies.
Revenue Recognition and Byproduct Recoveries			Revenue Recognition—The Company recognizes its printing revenues upon transfer of title and the passage of risk of loss, which is generally upon shipment to the customer. Under agreements with certain customers, products may be stored by the Company for future delivery. In these situations, the Company may receive warehouse management fees for the services it provides. In certain of these cases, delivery and billing schedules are outlined in the customer agreement and product revenue is recognized when manufacturing is complete, title and risk of loss transfer to the customer, and there is a reasonable assurance as to collectability. Product returns are not significant because the majority of products are customized; however, the Company accrues for the estimated amount of customer allowances at the time of sale based on historical experience and known trends.
			Revenue from services is recognized as services are performed. Revenues related to the Company's imaging operations, which include digital content management, photography, color services and page production, are recognized in accordance with the terms of the contract, typically upon completion of the performed service and acceptance by the customer. Revenues related to the Company's logistics operations, which includes the delivery of printed material, are recognized upon completion of the delivery of services.
			The Company also manufactures printing-related auxiliary equipment to ensure industry-leading technology for its own printing operations, as well as to sell to other businesses. Revenue is generally recognized for the equipment sales at time of shipment. Revenue from services related to the installation of equipment at customer sites are recognized upon completion of the installation. Payments can be received from customers during the manufacture of equipment and prior to shipment or in the case of the installation services prior to completion of the installation. In all cases when payments are received in advance of meeting the applicable revenue recognition criteria, deferred revenue is recorded until the criteria for revenue recognition are subsequently met.
			Services account for greater than 10% of the Company's consolidated net sales; therefore, net sales and related costs of sales of products and services have been included as separate line items in the consolidated statements of operations.
			Certain revenues earned by the Company require judgment to determine if revenue should be recorded gross as a principal or net of related costs as an agent. Billings for third-party shipping and handling costs, primarily in the Company's logistics operations, and out-of-pocket expenses are recorded gross in net sales and cost of sales in the consolidated statements of operations. Many of the Company's operations process materials, primarily paper, that may be supplied directly by customers or may be purchased by the Company and sold to customers. No revenue is recognized for customer-supplied paper. Revenues for Company-supplied paper are recognized on a gross basis.
			Byproduct Recoveries—The Company records the sale of byproducts as net product sales in the consolidated statements of operations.
Financial Instruments			Financial Instruments—The Company uses derivative financial instruments for the purpose of hedging commodity and foreign exchange exposures that exist as part of ongoing business operations, including natural gas forward purchase contracts and foreign exchange contracts. As a policy, the Company does not engage in speculative or leveraged transactions, nor does the Company hold or issue financial instruments for trading purposes.
			Derivative instruments are recorded on the consolidated balance sheets as either assets or liabilities measured at their fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged item affects earnings.
			The ineffective portions of the changes in the fair value of hedges are recognized in earnings. Cash flows from derivatives that are accounted for as cash flow or fair value hedges are included in the consolidated statements of cash flows in the same category as the item being hedged.
Fair Value Measurement			Fair Value Measurement—The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities that are required to be recorded at fair value, the Company considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability. See Note 18, "Financial Instruments and Fair Value Measurements," for further discussion.
Research and development			Research and Development—Research and development costs related to the development of new products or the adaptation of existing products are expensed as incurred, included in cost of sales
Cash and cash equivalents			Cash and Cash Equivalents—The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
Receivables			Receivables—Receivables are stated net of allowances for doubtful accounts. No single customer comprised more than 5% of the Company's consolidated net sales in 2013, 2012 or 2011 or 5% of the Company's consolidated receivables as of December 31, 2013 or 2012. Specific customer provisions are made when a review of significant outstanding amounts, utilizing information about customer creditworthiness and current economic trends, indicates that collection is doubtful. In addition, provisions are made at differing rates, based upon the age of the receivable and the Company's historical collection experience. See Note 7, "Receivables," for further discussion on the transactions affecting the allowances for doubtful accounts.
Inventories			Inventories—Inventories include material, labor, and plant overhead and are stated at the lower of cost or market. At December 31, 2013 and 2012, all inventories were valued using the first-in, first-out ("FIFO") method. See Note 8, "Inventories," for a breakdown of the components of the Company's inventories.
Property, Plant and Equipment			Property, Plant and Equipment—Property, plant and equipment are recorded at cost, and are depreciated over the estimated useful lives of the assets using the straight-line method for financial reporting purposes. See Note 9, "Property, Plant and Equipment," for a breakdown of the components of the Company's property, plant and equipment. Major improvements that extend the useful lives of existing assets are capitalized and charged to the asset accounts. Repairs and maintenance, which do not significantly improve or extend the useful lives of the respective assets, are expensed as incurred. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective asset.
			Asset Category	Range of Useful Lives
			Buildings	10 to 40 Years
			Machinery and equipment	5 to 15 Years
			Other	3 to 10 Years
Other Intangible Assets, Impairment of Long-Lived and Other Intangible Assets, and Goodwill			Other Intangible Assets—Identifiable intangible assets are recognized apart from goodwill and are amortized over their estimated useful lives.
			Impairment of Long-Lived and Other Intangible Assets—The Company evaluates long-lived assets and other intangible assets (of which the most significant are property, plant and equipment and customer relationship intangible assets) whenever events and circumstances have occurred that indicate the carrying value of an asset may not be recoverable. Determining whether impairment has occurred typically requires various estimates and assumptions, including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount and the asset's residual value, if any. In turn, measurement of an impairment loss requires a determination of recoverability, which is generally estimated by the ability to recover the balance of the assets from expected future operating cash flows on an undiscounted basis. If impairment is determined to exist, any related impairment loss is calculated based on the difference in the fair value and carrying value of the asset.
			Goodwill—Goodwill is reviewed annually for impairment as of October 31, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. In performing this analysis, the Company compares each reporting unit's fair value estimated based on comparable company market valuations and/or expected future discounted cash flows to be generated by the reporting unit to its carrying value. If the carrying value exceeds the reporting unit's fair value, the Company performs a fair value measurement calculation to determine the impairment loss, which would be charged to operations in the period identified. See Note 6, "Goodwill and Other Intangible Assets," for further discussion.
Income Taxes			Income Taxes—The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of items reported in the financial statements. Under this method, deferred tax assets and liabilities are measured based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the effective date of enactment.
			The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. This determination is based upon all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. If the Company determines that a deferred income tax asset will not be fully realized in the future, then a valuation allowance is established or increased to reflect the amount at which the asset will more likely than not be realized, which would increase the Company's provision for income taxes. In a period after a valuation allowance has been established, if the Company determines the related deferred income tax assets will be realized in the future in excess of their net recorded amount, then an adjustment to reduce the related valuation allowance will be made, which would reduce the Company's provision for income taxes.
			The Company is regularly audited by foreign and domestic tax authorities. These audits occasionally result in proposed assessments where the ultimate resolution might result in the Company owing additional taxes, including in some cases, penalties and interest. The Company recognizes a tax position in its consolidated financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. This recognized tax position is then measured at the largest amount of benefit that is greater than fifty-percent likely of being recognized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense.
			The determination of the Company's worldwide tax provision and related tax assets and liabilities requires the use of significant judgment, estimates, and the interpretation of complex tax laws. In the ordinary course of business, there are transactions and calculations where the final tax outcome is uncertain. While the Company believes it has the appropriate support for the positions taken, certain positions may be successfully challenged by taxing authorities. The Company applies the provisions of the authoritative guidance on accounting for uncertain tax positions to determine the appropriate amount of tax benefits to be recognized with respect to uncertain tax positions. The determination of the Company's worldwide tax provision includes the impact of any changes to the amount of tax benefits recognized with respect to uncertain tax positions.
Pension and Postretirement Plans			Pension and Postretirement Plans—The Company assumed certain underfunded defined benefit pension and postretirement benefit plans as part of the 2010 World Color Press acquisition. Pension plan costs are determined using actuarial methods and are funded through contributions. The Company records amounts relating to its pension and postretirement benefit plans based on calculations which include various actuarial assumptions including discount rates, mortality, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. The Company reviews its actuarial assumptions on an annual basis and modifies the assumptions based on current rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the consolidated balance sheets, but are generally amortized into operating income over future periods, with the deferred amount recorded in accumulated other comprehensive income (loss) on the consolidated balance sheets. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. For the purposes of calculating the expected return on plan assets, those assets are valued at fair value. When an event gives rise to both a curtailment and a settlement, the curtailment is accounted for prior to the settlement. The Company's measurement date to measure the defined benefit plan assets and the projected benefit obligation is December 31.
			In addition, as a result of the acquisition of World Color Press, the Company participated in multiemployer pension plans ("MEPPs"). Due to the significant underfunded status of the MEPPs, the Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan, which is historically the form of retirement benefit provided to Quad/Graphics employees. As a result of the decision to withdraw, the Company recorded an estimated withdrawal liability for the MEPPs as part of the purchase price allocation process based on information received from the MEPPs trustees. The estimated withdrawal liability will be updated as new withdrawal liability projections are provided from each plan's trustees until the final withdrawal liability is determined and paid. The exact amount of its withdrawal liability could be higher or lower than the estimate depending on, among other things, the nature and timing of any triggering events and the funded status of the plans at that time. See Note 20, "Employee Retirement Plans," for further discussion.
Stock-Based Compensation	The Company recognizes compensation expense, based on estimated grant date fair values, for all share-based awards issued to employees and non-employee directors, including stock options, performance shares, performance share units, restricted stock, restricted stock units and deferred stock units. The Company recognizes these compensation costs for only those awards expected to vest, on a straight-line basis over the requisite three to four year service period of the awards, except deferred stock units, which are fully vested and expensed on the grant date. The Company estimated the number of awards expected to vest based, in part, on historical forfeiture rates and also based on management's expectations of employee turnover within the specific employee groups receiving each type of award. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods, if actual forfeitures differ from those estimates.		Stock-Based Compensation—The Company recognizes stock-based compensation expense over the vesting period for all stock-based awards made to employees and directors based on the fair value of the instrument at the time of grant.
Accumulated Other Comprehensive Income (Loss)			Accumulated Other Comprehensive Income (Loss)—Accumulated other comprehensive income (loss) consists of unrecognized actuarial gains and losses and prior service costs for pension and postretirement plans and foreign currency translation adjustments and is presented in the consolidated statements of redeemable equity, common stock and other equity and noncontrolling interests. See Note 24, "Accumulated Other Comprehensive Income (Loss)," for further discussion.
Earnings (Loss) Per Share Attributable to Quad/Graphics Common Shareholders	Basic earnings (loss) per share attributable to Quad/Graphics common shareholders is computed as net earnings (loss) attributable to Quad/Graphics common shareholders less the allocation of participating securities, divided by the basic weighted average common shares outstanding of 47.5 million and 47.4 million shares for the three and nine months ended September 30, 2014, respectively, and 47.0 million and 46.9 million shares for the three and nine months ended September 30, 2013, respectively. The calculation of diluted earnings per share includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of (1) the amount the employee must pay upon exercise of the award, (2) the amount of unearned stock-based compensation costs attributed to future services and (3) the amount of tax benefits, if any, that would be credited to additional paid-in capital assuming exercise of the award. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net losses, and accordingly, the Company excludes them from the calculation. Due to the net loss attributable to Quad/Graphics common shareholders incurred during the nine months ended September 30, 2014 and 2013, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, not included in the diluted loss per share attributable to Quad/Graphics common shareholders calculation for those periods. Anti-dilutive equity instruments of 2.0 million and 2.9 million of class A common shares were excluded from the computation of diluted net earnings (loss) per share for the three and nine months ended September 30, 2014, respectively. Anti-dilutive equity instruments of 0.8 million and 2.8 million of class A common shares were excluded from the computation of diluted net earnings (loss) per share for the three and nine months ended September 30, 2013, respectively. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are required to be treated as participating securities and included in the computation of earnings (loss) per share pursuant to the two-class method. The Company's participating securities are composed of unvested stock options granted on November 18, 2011. The Company's participating securities had no impact on basic and diluted earnings per share attributable to Quad/Graphics common shareholders for the three months ended September 30, 2014, and increased basic and diluted loss per share attributable to Quad/Graphics common shareholders by $0.01 for the nine months ended September 30, 2014. The Company's participating securities decreased basic and diluted earnings per share attributable to Quad/Graphics common shareholders by $0.01 for the three months ended September 30, 2013, and increased basic and diluted loss per share attributable to Quad/Graphics common shareholders by $0.02 for the nine months ended September 30, 2013.		Basic earnings (loss) per share attributable to Quad/Graphics common shareholders is computed as net earnings (loss) attributable to Quad/Graphics common shareholders less the allocation of participating securities, divided by the basic weighted average common shares outstanding of 47.0 million, 46.8 million and 47.1 million shares for the years ended December 31, 2013, 2012 and 2011, respectively. The calculation of a diluted earnings per share amount includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of (1) the amount the employee must pay upon exercise of the award, (2) the amount of unearned stock-based compensation costs attributed to future services and (3) the amount of tax benefits, if any, that would be credited to additional paid-in capital assuming exercise of the award. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net earnings from continuing operations, and accordingly, the Company excludes them from the calculation. Anti-dilutive equity incentive instruments of 1.6 million and 3.2 million of class A common shares were excluded from the computations of diluted net earnings per share for the years ended December 31, 2013 and 2012, respectively. Due to the net loss from continuing operations attributable to Quad/Graphics common shareholders incurred during the year ended December 31, 2011, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, not included in the diluted loss per share attributable to Quad/Graphics common shareholders calculation for that period.
			Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are required to be treated as participating securities and included in the computation of earnings (loss) per share pursuant to the two-class method. The Company's participating securities are composed of unvested stock options granted on November 18, 2011, and reduced basic and diluted earnings per share attributable to Quad/Graphics common shareholders by $0.02 and $0.07 per diluted share for the years ended December 31, 2013 and 2012, respectively. There was no impact to basic and diluted earnings per share attributable to Quad/Graphics common shareholders during 2011.
Fair Value Measurement, Policy	Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded at fair value on a nonrecurring basis, generally as a result of acquisitions or impairment charges. Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. GAAP also classifies the inputs used to measure fair value into the following hierarchy:
	Level 1:	Quoted prices in active markets for identical assets or liabilities.
	Level 2:	Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.
	Level 3:	Unobservable inputs for the asset or liability. There are no Level 3 recurring measurements of assets or liabilities as of September 30, 2014.
	The Company records the fair value of its forward contracts and pension plan assets on a recurring basis. The fair value of cash and cash equivalents, receivables, inventories, restricted cash, accounts payable, accrued liabilities and amounts owing in satisfaction of bankruptcy claims approximate their carrying values as of September 30, 2014 and December 31, 2013. See Note 10, "Debt," for further discussion on the fair value of the Company's debt.
	In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company is required to record certain assets and liabilities at fair value on a nonrecurring basis, generally as a result of acquisitions or the remeasurement of assets resulting in impairment charges. See Note 2, "Acquisitions and Strategic Investments," for further discussion on acquisitions and Note 3, "Restructuring, Impairment and Transaction-Related Charges," for further discussion on impairment charges recorded as a result of the remeasurement of certain long-lived assets.

The notes are collateralized by certain United States land, buildings and press and finishing equipment under the terms of the master note and security agreement.
	Total debt	$	1,608.00		$	1,393.30
								-2	On July 26, 2011, and as last amended on December 19, 2012, the Company entered into a $1.5 billion debt financing agreement with certain lenders to reduce the Company's borrowing costs with lower interest rates and to create more flexibility with a higher revolving credit capacity and improvement in financial terms. The $1.5 billion debt financing agreement includes three different loan facilities, a Term Loan A, a Term Loan B, and a revolving credit facility.
	Less: short-term debt and current portion of long-term debt	(102.2		)	(127.6		)
	Long-term debt	$	1,505.80		$	1,265.70		The revolving credit facility in the amount of $850.0 million and the Term Loan A in the aggregate amount of $450.0 million each had an initial term of five years that was extended an additional year as part of the December 19, 2012 amendment to mature on July 25, 2017. The Term Loan B in the amount of $200.0 million (net of a $1.0 million original issue discount) has a term of seven years maturing on July 25, 2018, subject to certain required amortization.
								Borrowings under the revolving facility and Term Loan A loans made under the $1.5 billion debt financing agreement bear interest at London Interbank Offered Rate ("LIBOR") plus 2.25%, or 1.25% in excess of an alternate base rate, and Term Loan B loans bear interest at LIBOR plus 3.00%, with a LIBOR floor of 1.00%, or 2.00% in excess of an alternative base rate at the Company's option. At December 31, 2013, the Company had borrowings of $209.8 million on the revolving credit agreement, as well as $44.0 million of issued letters of credit, leaving $596.2 million available for future borrowings.
								The proceeds from the Term Loan A, Term Loan B and revolving credit facility were used to repay all outstanding balances and terminate the Company's previous $1.23 billion debt financing agreement (which included the $700.0 million term loan and the $530.0 million revolving credit facility), as well as to pay the new debt issuance costs incurred for the refinancing. The $1.5 billion debt financing agreement is secured by substantially all of the assets in the United States that are not encumbered under the Company's other financing agreements.
								The Company recognized a $34.0 million loss on debt extinguishment during the year ended December 31, 2011, in connection with the July 26, 2011 $1.5 billion debt financing agreement. The loss was comprised of: (1) $20.9 million of debt issuance costs from the terminated $1.23 billion debt financing agreement, (2) $8.9 million of remaining original issue discount from the terminated $1.23 billion debt financing agreement and (3) $4.2 million of debt issuance costs from the $1.5 billion debt financing agreement. The $34.0 million loss was classified as loss on debt extinguishment in the consolidated statements of operations.
								-3	On December 16, 2008, debt related to the Company's international operations was refinanced by entering into a secured credit agreement ("Facilities Agreement"). The Facilities Agreement includes a Euro denominated term loan and a multicurrency revolving credit facility. The term loan principal payments commenced in December 2009 and it matures on December 16, 2015. The multicurrency revolving credit facility used for financing working capital and general business needs, was renewed in 2013 and will expire on December 16, 2014. At December 31, 2013, the Company's international operations had borrowings of $2.3 million under the multicurrency revolving credit facility, leaving $14.3 million available for future borrowing. The terms of the Facilities Agreement include certain financial covenants, a guarantee of the Facilities Agreement by the Company and a security agreement that includes collateralizing substantially all of the Quad/Winkowski assets. The facilities bear interest at the aggregate of the Warsaw Interbank Offered Rate ("WIBOR") or the Euro Interbank Offered Rate ("EURIBOR") and margin.
								-4	During 2013, the Company refinanced certain equipment leases with $17.1 million in equipment term loans secured by the formerly leased equipment. The equipment term loans bear interest at a fixed rate of 4.75%, require quarterly payments and have five year terms expiring during 2018. The purchase of these assets resulted in $12.8 million of non-cash investing and financing activities, which represents the $17.1 million in equipment term loans net of $4.3 million of eliminated capital lease obligations (see Note 1, "Basis of Presentation and Summary of Significant Accounting Policies").

[1]	These senior notes have a weighted-average interest rate of 7.47%, which is fixed to maturity, with interest payable semiannually. Principal payments commenced September 1997 and extend through April 2036 in various tranches. The notes are collateralized by certain United States land, buildings and press and finishing equipment under the terms of the master note and security agreement.
[2]	On July 26, 2011, and as last amended on December 19, 2012, the Company entered into a $1.5 billion debt financing agreement with certain lenders to reduce the Company's borrowing costs with lower interest rates and to create more flexibility with a higher revolving credit capacity and improvement in financial terms. The $1.5 billion debt financing agreement includes three different loan facilities, a Term Loan A, a Term Loan B, and a revolving credit facility.The revolving credit facility in the amount of $850.0 million and the Term Loan A in the aggregate amount of $450.0 million each had an initial term of five years that was extended an additional year as part of the December 19, 2012 amendment to mature on July 25, 2017. The Term Loan B in the amount of $200.0 million (net of a $1.0 million original issue discount) has a term of seven years maturing on July 25, 2018, subject to certain required amortization.Borrowings under the revolving facility and Term Loan A loans made under the $1.5 billion debt financing agreement bear interest at London Interbank Offered Rate ("LIBOR") plus 2.25%, or 1.25% in excess of an alternate base rate, and Term Loan B loans bear interest at LIBOR plus 3.00%, with a LIBOR floor of 1.00%, or 2.00% in excess of an alternative base rate at the Company's option. At December 31, 2013, the Company had borrowings of $209.8 million on the revolving credit agreement, as well as $44.0 million of issued letters of credit, leaving $596.2 million available for future borrowings.The proceeds from the Term Loan A, Term Loan B and revolving credit facility were used to repay all outstanding balances and terminate the Company's previous $1.23 billion debt financing agreement (which included the $700.0 million term loan and the $530.0 million revolving credit facility), as well as to pay the new debt issuance costs incurred for the refinancing. The $1.5 billion debt financing agreement is secured by substantially all of the assets in the United States that are not encumbered under the Company's other financing agreements.The Company recognized a $34.0 million loss on debt extinguishment during the year ended December 31, 2011, in connection with the July 26, 2011 $1.5 billion debt financing agreement. The loss was comprised of: (1) $20.9 million of debt issuance costs from the terminated $1.23 billion debt financing agreement, (2) $8.9 million of remaining original issue discount from the terminated $1.23 billion debt financing agreement and (3) $4.2 million of debt issuance costs from the $1.5 billion debt financing agreement. The $34.0 million loss was classified as loss on debt extinguishment in the consolidated statements of operations.
[3]	On December 16, 2008, debt related to the Company's international operations was refinanced by entering into a secured credit agreement ("Facilities Agreement"). The Facilities Agreement includes a Euro denominated term loan and a multicurrency revolving credit facility. The term loan principal payments commenced in December 2009 and it matures on December 16, 2015. The multicurrency revolving credit facility used for financing working capital and general business needs, was renewed in 2013 and will expire on December 16, 2014. At December 31, 2013, the Company's international operations had borrowings of $2.3 million under the multicurrency revolving credit facility, leaving $14.3 million available for future borrowing. The terms of the Facilities Agreement include certain financial covenants, a guarantee of the Facilities Agreement by the Company and a security agreement that includes collateralizing substantially all of the Quad/Winkowski assets. The facilities bear interest at the aggregate of the Warsaw Interbank Offered Rate ("WIBOR") or the Euro Interbank Offered Rate ("EURIBOR") and margin.
[4]	During 2013, the Company refinanced certain equipment leases with $17.1 million in equipment term loans secured by the formerly leased equipment. The equipment term loans bear interest at a fixed rate of 4.75%, require quarterly payments and have five year terms expiring during 2018. The purchase of these assets resulted in $12.8 million of non-cash investing and financing activities, which represents the $17.1 million in equipment term loans net of $4.3 million of eliminated capital lease obligations (see Note 1, "Basis of Presentation and Summary of Significant Accounting Policies").
