Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements for Quad/Graphics, Inc. and its subsidiaries (the “Company” or “Quad”) 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. 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, 2018 , and notes thereto included in the Company’s latest Annual Report on Form 10-K filed with the SEC on February 20, 2019 . The Company is subject to seasonality in its quarterly results as net sales and operating income are higher in the third and fourth quarters of the calendar year as compared to the first and second quarters. The fourth quarter is typically the highest seasonal quarter for cash flows from operating activities due to the reduction of working capital requirements that reach peak levels during the third quarter. 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 adjustments, in the opinion of management, necessary for a fair presentation of the Company’s results of operations for the three and six months ended June 30, 2019 and 2018 . All of these adjustments are of a normal recurring nature, except as otherwise noted. 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. Leases On January 1, 2019, the Company adopted Accounting Standards Update 2016-02, “Leases (Topic 842)” (“ Topic 842 ”), which establishes a right-of-use model requiring a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition. The Company adopted Topic 842 using the modified retrospective approach and applied the new guidance to those contracts existing at, or entered into after, January 1, 2019. See Note 10 , “ Leases ,” for additional accounting policy and transition disclosures.

Costs to Obtain Contracts In accordance with Accounting Standards Codification (“ ASC ”) 606 — Revenue from Contracts with Customers , the Company capitalizes certain sales incentives of the sales compensation packages for costs that are directly attributed to being awarded a customer contract or renewal and would not have been incurred had the contract not been obtained. The Company also defers certain contract acquisition costs paid to the customer at contract inception. Costs to obtain contracts with a duration of less than one year are expensed as incurred. For all contract costs with contracts over one year, the Company amortizes the costs to obtain contracts on a straight-line basis over the estimated life of the contract and reviews quarterly for impairment. Activity impacting costs to obtain contracts for the six months ended June 30, 2019 , was as follows: Costs to Obtain Contracts Balance at January 1, 2019 $ 21.7 Costs to obtain contracts 2.8 Amortization of costs to obtain contracts (4.9 ) Balance at June 30, 2019 $ 19.6 Remaining Performance Obligations For certain performance obligations related to print contracts, the Company has elected not to disclose the value of unsatisfied performance obligations for the following: (1) contracts that have an original expected length of one year or less; (2) contracts where revenue is recognized as invoiced; or (3) contracts with variable consideration related to unsatisfied performance obligations. The Company had approximately $316.4 million in volume commitments in contracts that extend beyond one year as of June 30, 2019 . The Company expects to recognize approximately 22% of these volume commitments in contracts as revenue by the end of 2019 , an additional 56% by the end of 2021 , and the balance thereafter.

See Note 19 , “ Segment Information ,” for restructuring, impairment and transaction-related charges by segment. Restructuring Charges The Company began a restructuring program in 2010 related to eliminating excess manufacturing capacity and properly aligning its cost structure and has since announced a total of 43 plant closures through June 30, 2019 . The Company classifies the following charges as restructuring: • Employee termination charges are incurred when the Company reduces its workforce through facility consolidations and separation programs. • Integration costs are incurred primarily for the integration of acquired companies (see Note 3 , “ Acquisitions and Strategic Investments ,” for descriptions of the Company’s recent acquisitions). • Other restructuring charges are presented net of the gains on the sale of facilities, including a $2.5 million gain on the sale of the Franklin, Kentucky facility during the second quarter of 2019, a $3.5 million gain on the sale of the Hazleton, Pennsylvania facility during the first quarter of 2019, and a $2.2 million gain on the sale of the San Ixhuatepec, Mexico facility during the first quarter of 2018. During the second quarter of 2019, the Company recorded $2.3 million in charges related to a value-added tax assessment for a closed facility, which is included within other restructuring activities during the three and six months ended June 30, 2019 , in the table below.

The Company expects to incur additional restructuring charges related to these and other initiatives. Impairment Charges The Company recognized impairment charges of $0.4 million and $2.1 million during the three and six months ended June 30, 2019 , respectively, primarily for machinery and equipment no longer being utilized in production as a result of facility consolidations, as well as other capacity reduction restructuring activities.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in a business combination. Goodwill is assigned to specific reporting units and 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 recorded $58.6 million of preliminary goodwill within the United States Print and Related Services segment related to the Periscope acquisition completed during the six months ended June 30, 2019 . The amount of preliminary goodwill is subject to the final determination of acquired working capital and completion of the final valuation of the net assets acquired. There was no other activity impacting goodwill for the six months ended June 30, 2019 . The accumulated goodwill impairment losses and the carrying value of goodwill at June 30, 2019 , and December 31, 2018 , were as follows: June 30, 2019 December 31, 2018 United States Print and Related Services International Total United States Print and Related Services International Total Goodwill $ 891.5 $ 30.0 $ 921.5 $ 832.9 $ 30.0 $ 862.9 Accumulated goodwill impairment loss (778.3 ) (30.0 ) (808.3 ) (778.3 ) (30.0 ) (808.3 ) Goodwill, net of accumulated goodwill impairment loss $ 113.2 $ — $ 113.2 $ 54.6 $ — $ 54.6 Other Intangible Assets The components of finite-lived intangible assets at June 30, 2019 , and December 31, 2018 , were as follows: June 30, 2019 December 31, 2018 Weighted Average Amortization Period (Years) Gross Carrying Amount Accumulated Amortization Net Book Value Weighted Gross Carrying Amount Accumulated Amortization Net Book Value Trademarks, patents, licenses and agreements 6 $ 69.1 $ (28.2 ) $ 40.9 7 $ 59.8 $ (22.4 ) $ 37.4 Capitalized software 5 15.7 (6.9 ) 8.8 5 15.3 (5.1 ) 10.2 Customer relationships 6 577.0 (465.0 ) 112.0 6 514.7 (449.7 ) 65.0 Total $ 661.8 $ (500.1 ) $ 161.7 $ 589.8 $ (477.2 ) $ 112.6 During the six months ended June 30, 2019 , the gross carrying amount of other intangible assets increased primarily due to $70.5 million of acquired identifiable finite-lived intangible assets as discussed in Note 3 , “ Acquisitions and Strategic Investments .” The gross carrying amount and accumulated amortization within other intangible assets—net in the condensed consolidated balance sheets at June 30, 2019 , and December 31, 2018 , differs from the value originally recorded at acquisition due to impairment charges recorded in prior years and the effects of currency fluctuations since the purchase date. Other intangible assets are evaluated for potential impairment whenever events or circumstances indicate that the carrying value may not be recoverable. There were no impairment charges recorded on finite-lived intangible assets for the three and six months ended June 30, 2019 and 2018 . Amortization expense for other intangible assets was $11.3 million and $22.9 million for the three and six months ended June 30, 2019 , respectively, and $8.2 million and $14.0 million for the three and six months ended June 30, 2018 , respectively.

Commitments and Contingencies	Commitments and Contingencies Litigation The Company is named as a defendant in various lawsuits in which claims are asserted against the Company in the normal course of business. The liabilities, if any, which ultimately result from such lawsuits are not expected by management to have a material impact on the condensed consolidated financial statements of the Company. In April 2016, the Company self-reported to the SEC and to the United States Department of Justice (“DOJ”) certain Foreign Corrupt Practices Act (“FCPA”) issues, and a resulting internal investigation, related to its operations managed from Peru. These operations had approximate annual sales ranging from $95.0 million to $135.0 million from the date that the Company acquired those operations in July 2010 until the date the issues were discovered. The self-reported issues were identified by the Company’s financial internal controls. The Company, under the oversight of its Audit Committee and Board of Directors, proactively initiated an investigation into this matter with the assistance of external legal counsel and external forensic accountants. Additional compliance issues arising out of the Peru subsidiary have been identified during the course of the investigation and are known to the SEC and DOJ. During the course of its internal investigation, the Company has also identified, and self-reported to the DOJ and SEC, transactions raising similar issues involving certain sales made in its Quad/Tech China operations. For the period 2011 through 2015, the approximate annual sales of these China operations ranged from $2.0 million to $3.0 million . During the course of its internal investigation, the Company has also identified and informed the Office of Foreign Assets Control (“OFAC”), the DOJ and the SEC, of certain transactions involving Cuba, and continues to investigate the propriety of such transactions under United States trade sanctions. The Peruvian antitrust authority (“INDECOPI”) currently is conducting an investigation into certain alleged past collusive activities among printers in Peru, including Quad/Graphics Peru. In connection with these matters, the Company has made, and continues to evaluate, certain enhancements to its compliance program. The Company is fully cooperating with the OFAC, the SEC, the DOJ and INDECOPI. At this time, the Company does not anticipate any material adverse effect on its business or financial condition as a result of these matters. Environmental Reserves The Company is subject to various laws, regulations and government policies relating to health and safety, to the generation, storage, transportation, and disposal of hazardous substances, and to environmental protection in general. The Company provides for expenses associated with environmental remediation obligations when such amounts are probable and can be reasonably estimated. Such reserves are adjusted as new information develops or as circumstances change. The environmental reserves are not discounted. The Company believes it is in compliance with such laws, regulations and government policies in all material respects. Furthermore, the Company does not anticipate that maintaining compliance with such environmental statutes will have a material impact upon the Company’s condensed consolidated financial position.

As the Company’s total leverage ratio as of June 30, 2019 , was 2.96 to 1.00, the limitations described above are currently applicable. • If the Company’s senior secured leverage ratio is greater than 3.00 to 1.00 or the Company’s total leverage ratio is greater than 3.50 to 1.00 (these ratios as defined in the Senior Secured Credit Facility), the Company is prohibited from voluntarily prepaying any of the Senior Unsecured Notes and from voluntarily prepaying any other unsecured or subordinated indebtedness, with certain exceptions (including any mandatory prepayments on the Senior Unsecured Notes or any other unsecured or subordinated debt). If the senior secured leverage ratio is less than 3.00 to 1.00 and the total leverage ratio is less than 3.50 to 1.00, there are no such restrictions. The limitations described above are currently not applicable, as the Company’s senior secured leverage ratio was 2.30 to 1.00 and total leverage ratio was 2.96 to 1.00, as of June 30, 2019 .

Leases [Abstract]
Leases	Leases The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date. For operating and finance leases, the lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date, and is subsequently measured at amortized cost using the effective interest method. Key estimates and judgments include how the Company determines the discount rate, lease term and lease payments. • Topic 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the implicit interest rate as it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms based on the published United States Treasury rates as well as the Company’s credit rating at implementation or at the lease inception date. • The lease term for all of the Company’s leases includes the noncancelable period of the lease, plus or minus any additional periods covered by an option to extend or terminate the lease that the Company is reasonably certain to exercise. • Lease payments included in the lease liability are comprised of fixed payments as well as any exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise. The Company’s leases do not contain variable lease payments. ROU assets are initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently amortized by the straight-line lease expense adjusted by the lease liability accretion over the lease term. For finance leases, the ROU asset is subsequently amortized on a straight-line basis from the lease commencement date to the earlier of the end of its useful life or the end of the lease term. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. The Company’s ROU assets for both operating and finance leases are reviewed for impairment losses on a quarterly basis in line with ASC 360-10 — Property, Plant, and Equipment — Overall. The Company has not recognized any impairment losses to date. The Company also monitors its leases for events or changes in circumstances that require a reassessment of the lease. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the ROU asset. Operating leases are included in operating lease right-of-use assets—net, current portion of operating lease obligations, and operating lease obligations in the condensed consolidated balance sheets. Finance leases are included in property and equipment—net, current portion of finance lease obligations, and finance lease obligations in the condensed consolidated balance sheets. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have an original lease term of twelve months or less. Therefore, the Company recognizes the lease payments associated with these short-term leases as an expense over the lease term in the condensed consolidated statement of operations. Adoption of Topic 842 — Transition Approach The Company adopted Topic 842 as of January 1, 2019 using the additional optional transition method pursuant to ASU 2018-11, meaning that restatement of prior period consolidated financial statements or presentation of comparative disclosures is not necessary. During adoption, the Company elected the following practical expedients allowed: • The Company elected the practical expedient package and therefore did not reassess for any existing leases: ◦ whether contracts are or contain leases; ◦ the lease classification for any existing leases; and ◦ any initial direct costs. • The Company elected the practical expedient related to land easements, allowing to carry forward the accounting treatment for land easements on existing agreements. • The Company used “hindsight” judgments that impact the lease term. • The Company elected to combine lease and non-lease components into one lease component for select underlying lease asset categories. Real estate leases are accounted for separately while all other leases, primarily equipment, leases with separate lease and non-lease components are accounted for as a single lease component. Adoption of the new standard resulted in the recording of operating lease right-of-use assets and operating lease obligations of $130.8 million and $132.4 million , respectively, as of January 1, 2019. The transition had no impact to the condensed consolidated statement of operations. Leases Financial Information The Company enters into various lease agreements for real estate, such as office space and manufacturing facilities, as well as equipment leases, including press, finishing and transportation equipment. Many of these leases provide the Company with options to renew, terminate, or in the case of equipment leases, purchase the related equipment at the termination value, as defined, and at various early buyout dates during the term of the lease. In general, the Company has determined these options were not reasonably certain to be exercised, and therefore are not included in the determination of the lease term. The following summarizes certain lease information for the three and six months ended June 30, 2019 : Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 Lease cost Finance lease cost: Amortization of right-of-use assets $ 1.4 $ 2.8 Interest on lease liabilities 0.3 0.5 Operating lease cost 10.8 21.7 Short-term lease cost 0.2 0.3 Sublease income (0.7 ) (1.3 ) Total lease cost $ 12.0 $ 24.0 Six Months Ended June 30, 2019 Other information Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from finance leases $ — Operating cash flows from operating leases 22.4 Financing cash flows from finance leases 2.9 Right-of-use assets obtained in exchange for new finance lease liabilities 2.4 Right-of-use assets obtained in exchange for new operating lease liabilities 12.6 Weighted-average remaining lease term — finance leases 2.9 years Weighted-average remaining lease term — operating leases 5.3 years Weighted-average discount rate — finance leases 6.5 % Weighted-average discount rate — operating leases 6.7 % Future maturities of lease liabilities at June 30, 2019 were as follows: Future Maturities of Operating Leases Future Maturities of Finance Leases Remainder of 2019 $ 22.1 $ 3.7 2020 37.9 5.6 2021 26.0 4.5 2022 19.3 2.1 2023 15.0 0.2 2024 and thereafter 32.7 — Total minimum payments 153.0 16.1 Less: present value discount (24.4 ) (1.3 ) Lease liability $ 128.6 $ 14.8 The following tables summarize certain lease information for the year ended December 31, 2018, prior to the implementation of Topic 842 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company records income tax expense (benefit) on an interim basis. The estimated effective income tax rate is adjusted quarterly, and items discrete to a specific quarter are reflected in income tax expense (benefit) for that interim period. The effective income tax rate for the interim period can differ from the statutory tax rate, as it reflects discrete items, such as changes in the liability for unrecognized tax benefits related to the establishment and settlement of income tax exposures and benefits related to share-based compensation. The Company currently has various open tax audits in multiple jurisdictions. From time to time, the Company will receive tax assessments as part of the process. Based on the information available as of June 30, 2019 , the Company has recorded its best estimate of the potential settlements of these audits. Actual results could differ from the estimated amounts. The Company’s liability for unrecognized tax benefits as of June 30, 2019 , was $13.8 million . The Company anticipates a $4.1 million decrease to its liability for unrecognized tax benefits within the next twelve months due to the resolution of income tax audits or statute expirations.

Financial Instruments and Fair

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	Financial Instruments and Fair Value Measurements 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 were no Level 3 recurring measurements of assets or liabilities as of June 30, 2019 . Interest Rate Swaps The Company currently holds two interest rate swap contracts designated as cash flow hedges, as the purpose is to reduce the variability of cash flows from interest payments related to a portion of Quad’s variable-rate debt. The swaps effectively convert the notional value of the Company’s variable rate debt based on one-month LIBOR to a fixed rate, including a spread on underlying debt, and a monthly reset in the variable interest rate. The key terms of the interest rate swaps are as follows: March 19, 2019 Interest Rate Swap February 7, 2017 Interest Rate Swap Effective date March 29, 2019 February 28, 2017 Termination date March 28, 2024 February 28, 2022 Term 5 years 5 years Notional amount $130.0 $250.0 Fixed swap rate 2.43% 1.89% The Company classifies the interest rate swaps as Level 2 because the inputs into the valuation model are observable or can be derived or corroborated utilizing observable market data at commonly quoted intervals. The fair value of the interest rate swaps classified as Level 2 as of June 30, 2019 , and December 31, 2018 , were as follows: Balance Sheet Location June 30, 2019 December 31, 2018 Interest rate swap assets Prepaid expenses and other current assets $ — $ 4.3 Interest rate swap liabilities Other long-term liabilities $ (6.2 ) $ — The interest rate swaps were highly effective as of June 30, 2019 . No amount of ineffectiveness has been recorded into earnings related to these cash flow hedges. The cash flows associated with the interest rate swaps have been recognized as an adjustment to interest expense in the condensed consolidated statements of operations, and the changes in the fair value of the interest rate swaps have been included in other comprehensive loss in the condensed consolidated statements of comprehensive income (loss): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Net interest paid (received) $ (0.4 ) $ — $ (0.8 ) $ 0.2 Gain (loss) recognized in other comprehensive income (loss) (6.9 ) 1.4 $ (10.6 ) $ 5.1 Foreign Exchange Contracts The Company has operations in countries that have transactions outside their functional currencies and periodically enters into foreign exchange contracts. These contracts are used to hedge the net exposures of changes in foreign currency exchange rates and are designated as either cash flow hedges or fair value hedges. Gains or losses on net foreign currency hedges are intended to offset losses or gains on the underlying net exposures in an effort to reduce the earnings volatility resulting from fluctuating foreign currency exchange rates. There were no open foreign currency exchange contracts as of June 30, 2019 . Natural Gas Forward Contracts The Company periodically enters into natural gas forward purchase contracts to hedge against increases in commodity costs. The Company’s commodity contracts qualified for the exception related to normal purchases and sales during the three and six months ended June 30, 2019 and 2018 , as the Company takes delivery in the normal course of business. Debt The Company measures fair value on its debt instruments using interest rates available to the Company for borrowings with similar terms and maturities and is categorized as Level 2. See Note 9 , “ Debt ,” for the fair value of the Company’s debt as of June 30, 2019 . Nonrecurring Fair Value Measurements 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 3 , “ Acquisitions and Strategic Investments ,” for further discussion on acquisitions. See Note 4 , “ Restructuring, Impairment and Transaction-Related Charges ” and Note 7 , “ Property, Plant and Equipment ” for further discussion on impairment charges recorded as a result of the remeasurement of certain long-lived assets. Other Estimated Fair Value Measurements 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, accounts payable and accrued liabilities approximate their carrying values as of June 30, 2019 , and December 31, 2018 .

Retirement Benefits [Abstract]
Employee Retirement Plans	Employee Retirement Plans Defined Contribution Plans The Quad/Graphics, Inc. Employee Stock Ownership Plan (“ ESOP ”) holds profit sharing contributions of Company stock, which are made at the discretion of the Company’s Board of Directors. The Company made a non-cash contribution of 1,006,061 shares of Company class A common stock at a stock price of $22.18 per share for a total value of $22.3 million to the ESOP during the six months ended June 30, 2018 . There were no profit sharing contributions during the three months ended June 30, 2018 , or during the three and six months ended June 30, 2019 . Pension Plans The Company assumed various funded and unfunded frozen pension plans for a portion of its full-time employees in the United States as part of the acquisition of World Color Press Inc. (“ World Color Press ”) in 2010. Benefits are generally based upon years of service and compensation. These plans are funded in conformity with the applicable government regulations. The Company funds at least the minimum amount required for all qualified plans using actuarial cost methods and assumptions acceptable under government regulations. The components of net pension income for the three and six months ended June 30, 2019 and 2018 , were as follows: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Interest cost $ (4.4 ) $ (4.0 ) $ (8.8 ) $ (8.0 ) Expected return on plan assets 5.9 7.1 11.8 14.2 Net pension income $ 1.5 $ 3.1 $ 3.0 $ 6.2 The Company made $0.5 million in benefit payments to its non-qualified defined benefit pension plans and made $2.1 million in contributions to its qualified defined benefit pension plans during the six months ended June 30, 2019 . Multiemployer Pension Plans (“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. 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 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 withdrawal liability based on information provided by each plan’s trustee. The Company has reserved $47.6 million for the total MEPPs withdrawal liability as of June 30, 2019 , of which $38.9 million was recorded in other long-term liabilities and $8.7 million was recorded in accrued liabilities in the condensed consolidated balance sheets. The Company is scheduled to make payments to the GCIU and GCC until April 2032 and February 2024, respectively. The Company made payments totaling $5.2 million and $7.3 million for the six months ended June 30, 2019 and 2018

Earnings Per Share [Abstract]
Earnings (Loss) Per Share Attributable to Quad/Graphics Common Shareholders	Earnings (Loss) Per Share Attributable to Quad Common Shareholders Basic earnings (loss) per share attributable to Quad common shareholders is computed as net earnings (loss) attributable to Quad common shareholders divided by the basic weighted average common shares outstanding. The calculation of diluted earnings (loss) per share attributable to Quad common shareholders 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 the amount the employee must pay upon exercise of the award and the amount of unearned stock-based compensation costs attributable to future services. 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, and accordingly, the Company excludes them from the calculation. Due to the net loss incurred during the three and six months ended June 30, 2019 , the assumed exercise of all equity incentive instruments was anti-dilutive and therefore, not included in the diluted loss per share calculation. Anti-dilutive equity instruments excluded from the computation of diluted net earnings per share were 0.3 million and 0.6 million class A common shares for the three and six months ended June 30, 2018 , respectively. 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 six months ended June 30, 2019 and 2018 , are summarized as follows: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Numerator Net earnings (loss) attributable to Quad common shareholders $ (14.8 ) $ 9.4 $ (37.3 ) $ 5.9 Denominator Basic weighted average number of common shares outstanding for all classes of common shares 50.1 50.8 49.9 50.5 Plus: effect of dilutive equity incentive instruments — 1.7 — 1.8 Diluted weighted average number of common shares outstanding for all classes of common shares 50.1 52.5 49.9 52.3 Earnings (loss) per share attributable to Quad common shareholders Basic $ (0.30 ) $ 0.19 $ (0.75 ) $ 0.12 Diluted $ (0.30 ) $ 0.18 $ (0.75 ) $ 0.11 Cash dividends paid per common share for all classes of common shares $ 0.30 $ 0.30 $ 0.60 $ 0.60

Share-based Payment Arrangement [Abstract]
Equity Incentive Programs	Equity Incentive Programs The shareholders of the Company approved the Quad/Graphics, Inc. 2010 Omnibus Incentive Plan (“Omnibus Plan”) for two complementary purposes: (1) to attract and retain outstanding individuals to serve as directors, officers and employees; and (2) to increase shareholder value. In May 2019, an additional 1,800,000 shares were approved for issuance, providing for an aggregate 12,671,652 shares of class A common 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 common stock, restricted stock (“RS”), restricted stock units (“RSU”), deferred stock units (“DSU”) 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 common stock on the date of grant. There were 1,614,562 shares of class A common stock reserved for issuance under the Omnibus Plan as of June 30, 2019 . Authorized unissued shares or treasury shares may be used for issuance under the Company’s equity incentive programs. The Company plans to either use treasury shares of its class A common stock or issue shares of class A common stock to meet the stock requirements of its awards in the future. 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, RS awards, RSU awards and DSU awards. 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. Equity Incentive Compensation Expense The total compensation expense recognized related to all equity incentive programs was $2.7 million and $7.7 million for the three and six months ended June 30, 2019 , respectively, and $3.7 million and $9.1 million for the three and six months ended June 30, 2018 , respectively, and was recorded primarily in selling, general and administrative expenses in the condensed consolidated statements of operations. Total stock-based compensation expense included $0.6 million of income recognized for liability awards that are remeasured on a quarterly basis during the three and six months ended June 30, 2019 . Total future compensation expense related to all equity incentive programs granted as of June 30, 2019 , was estimated to be $22.8 million , which consists entirely of expense for RS and RSU awards. Estimated future compensation expense is $7.0 million for the remainder of 2019 , $9.8 million for 2020 , $5.3 million for 2021 and $0.7 million for 2022 . Stock Options 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. There were no stock options granted, and no compensation expense was recognized related to stock options for the three and six months ended June 30, 2019 and 2018 . There is no future compensation expense for stock options as of June 30, 2019 . The following table is a summary of the stock option activity for the six months ended June 30, 2019 : Shares Under Option Weighted Average Exercise Price Weighted Average Remaining Contractual Term (years) Aggregate Intrinsic Value (millions) Outstanding at December 31, 2018 942,315 $ 24.31 1.8 $ — Granted — — Exercised — — Canceled/forfeited/expired (144,900 ) 18.27 Outstanding and exercisable at June 30, 2019 797,415 $ 25.41 1.6 $ — The intrinsic value of options outstanding and exercisable at June 30, 2019 , and December 31, 2018 , was based on the fair value of the stock price.

The awards are restricted such that they are subject to substantial risk of forfeiture and to restrictions on their sale or other transfer by the employee. RSU awards are typically granted to eligible employees outside of the United States. 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. Grantees receiving RS awards are able to exercise full voting rights and receive full credit for dividends during the vesting period. All such dividends will be paid to the RS grantee within 45 days of full vesting. Grantees receiving RSU awards are not entitled to vote, but do earn dividends. Upon vesting, RSU awards will be settled either through cash payment equal to the fair market value of the RSU awards on the vesting date or through issuance of the Company’s class A common stock. The following table is a summary of RS and RSU award activity for the six months ended June 30, 2019 : Restricted Stock Restricted Stock Units Shares Weighted- Average Grant Date Fair Value Per Share Weighted- Average Remaining Contractual Term (years) Units Weighted- Average Grant Date Fair Value Per Share Weighted- Average Remaining Contractual Term (years) Nonvested at December 31, 2018 2,335,916 $ 17.36 1.0 107,092 $ 16.70 0.8 Granted 1,500,434 12.32 186,807 12.33 Vested (1,118,071 ) 9.46 (58,187 ) 9.51 Forfeited (14,389 ) 20.12 (5,091 ) 26.88 Nonvested at June 30, 2019 2,703,890 $ 17.82 2.0 230,621 $ 14.75 2.4 In the first quarter of 2019, the Company issued RSU awards in connection with the acquisition of Periscope that are accounted for as liability awards that will vest on March 1, 2022. The awards were recorded at fair value on the initial issuance date and are remeasured to fair value at each reporting period, with the change in fair value being recorded in selling, general and administrative expense in the condensed consolidated statements of operations. The change in fair value of the awards classified as liabilities resulted in income of $0.6 million for the three and six months ended June 30, 2019 . As of June 30, 2019 , the fair value of the RSU awards classified as liabilities was $1.1 million and was included in other long-term liabilities on the condensed consolidated balance sheets. In general, RS and RSU awards will vest on the third anniversary of the grant date, provided the holder of the share is continuously employed by the Company until the vesting date.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2018-15 “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (“ASU 2018-15”), which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Entities are allowed to apply either a retrospective or prospective transition approach to adopt the guidance. The Company is evaluating the impact of the adoption of ASU 2018-15 on the condensed consolidated financial statements. In August 2018, the FASB issued Accounting Standards Update 2018-14 “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 2018-14”), which adds, removes and clarifies year-end disclosure requirements related to defined benefit pension and other postretirement plans. This guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. This new guidance will require a retrospective adoption approach. The Company is evaluating the impact of the adoption of ASU 2018-14 on the notes to the condensed consolidated financial statements. In August 2018, the FASB issued Accounting Standards Update 2018-13 “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which changes the requirements on fair value measurements by removing, modifying or adding certain disclosures. This guidance is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Entities electing to early adopt are permitted to early adopt the eliminated or modified disclosure requirements and delay the adoption of all the new disclosure requirements until their effective date. The adoption of ASU 2018-13 requires the application of a combination of the prospective and retrospective methods of transition, depending on the topic of disclosure. The Company is evaluating the impact of the adoption of ASU 2018-13 on the notes to the condensed consolidated financial statements. In June 2016, the FASB issued Accounting Standards Update 2016-13 “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which changes the impairment model for most financial assets and certain other instruments. Under the new guidance, entities will be required to measure expected credit losses for financial instruments, including trade receivables, based on historical experience, current conditions and reasonable forecasts. This guidance is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for interim and annual periods beginning after December 15, 2018. This new guidance will require a modified retrospective transition approach, where the entity will need to apply a cumulative-effect adjustment to retained earnings (accumulated deficit) as of the beginning of the first reporting period in which the guidance is adopted.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fair Value Measurement	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 were no Level 3 recurring measurements of assets or liabilities as of June 30, 2019 .
Earnings Per Share	The calculation of diluted earnings (loss) per share attributable to Quad common shareholders 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 the amount the employee must pay upon exercise of the award and the amount of unearned stock-based compensation costs attributable to future services.
Share-based Compensation, Option and Incentive Plans	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, RS awards, RSU awards and DSU awards. 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.

Leases	The Company enters into various lease agreements for real estate, such as office space and manufacturing facilities, as well as equipment leases, including press, finishing and transportation equipment. Many of these leases provide the Company with options to renew, terminate, or in the case of equipment leases, purchase the related equipment at the termination value, as defined, and at various early buyout dates during the term of the lease. In general, the Company has determined these options were not reasonably certain to be exercised, and therefore are not included in the determination of the lease term. The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date. For operating and finance leases, the lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date, and is subsequently measured at amortized cost using the effective interest method. Key estimates and judgments include how the Company determines the discount rate, lease term and lease payments. • Topic 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the implicit interest rate as it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms based on the published United States Treasury rates as well as the Company’s credit rating at implementation or at the lease inception date. • The lease term for all of the Company’s leases includes the noncancelable period of the lease, plus or minus any additional periods covered by an option to extend or terminate the lease that the Company is reasonably certain to exercise. • Lease payments included in the lease liability are comprised of fixed payments as well as any exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise. The Company’s leases do not contain variable lease payments. ROU assets are initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently amortized by the straight-line lease expense adjusted by the lease liability accretion over the lease term. For finance leases, the ROU asset is subsequently amortized on a straight-line basis from the lease commencement date to the earlier of the end of its useful life or the end of the lease term. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. The Company’s ROU assets for both operating and finance leases are reviewed for impairment losses on a quarterly basis in line with ASC 360-10 — Property, Plant, and Equipment — Overall. The Company has not recognized any impairment losses to date. The Company also monitors its leases for events or changes in circumstances that require a reassessment of the lease. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the ROU asset. Operating leases are included in operating lease right-of-use assets—net, current portion of operating lease obligations, and operating lease obligations in the condensed consolidated balance sheets. Finance leases are included in property and equipment—net, current portion of finance lease obligations, and finance lease obligations in the condensed consolidated balance sheets. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have an original lease term of twelve months or less. Therefore, the Company recognizes the lease payments associated with these short-term leases as an expense over the lease term in the condensed consolidated statement of operations.
