Accounting Policies [Abstract]
Overview and Basis of Presentation	Note 1. Overview and Basis of Presentation Description of Business Donnelley Financial Solutions, Inc. (the Donnelley Financial’s Registration Statement on Form 10, as amended, was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on September 20, 2016. On October 1, 2016, Donnelley Financial became an independent publicly traded company through the distribution by R.R. Donnelley & Sons Company (“RRD”) of approximately 26.2 million shares, or 80.75%, of Donnelley Financial common stock to RRD shareholders (the “Separation”). Holders of RRD common stock received one share of Donnelley Financial common stock for every eight shares of RRD common stock held on September 23, 2016. As part of the Separation, RRD retained approximately 6.2 million shares of Donnelley Financial common stock, or a 19.25% interest in Donnelley Financial. Donnelley Financial’s common stock began regular-way trading under the ticker symbol “DFIN” on the New York Stock Exchange on October 3, 2016. On October 1, 2016, RRD also completed the previously announced separation of LSC Communications, Inc. (“LSC”), its publishing and retail-centric print services and office products business. On March 28, 2017, RRD completed the sale of 6.2 million shares of LSC common stock (RRD’s remaining ownership stake in LSC) in an underwritten public offering. Beginning in the quarter ended June 30, 2017, LSC no longer qualified as a related party, therefore amounts disclosed related to LSC are presented through March 31, 2017 only. On March 24, 2017, pursuant to the Stockholder and Registration Rights Agreement, dated as of September 30, 2016, by and between the Company and RRD, the Company filed a Registration Statement on Form S-1 to register the offering and sale of shares of the Company’s common stock retained by RRD. The Registration Statement on Form S-1, as amended, was declared effective by the SEC on June 13, 2017. On June 21, 2017, RRD completed the sale of approximately 6.1 million shares of the Company’s common stock in an underwritten public offering. Upon the consummation of the offering, RRD retained approximately 0.1 million shares of the Company’s common stock which were subsequently sold by RRD on August 4, 2017. In conjunction with the underwritten public offering, the underwriters exercised their option to purchase approximately 0.9 million of the Company’s shares (the “Option Shares”). The Company received approximately $18.8 million in net proceeds from the sale of the Option Shares, after deducting estimated underwriting discounts and commissions. The proceeds were used to reduce outstanding debt under the Revolving Facility (as defined in Note 15, Debt ). Beginning in the quarter ended September 30, 2017, RRD no longer qualified as a related party, therefore amounts disclosed related to RRD are presented through June 30, 2017 only. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Donnelley Financial and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The financial data presented herein should be read in conjunction with the audited consolidated and combined financial statements and accompanying notes included in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on February 28, 2018. In the opinion of management, the financial data presented includes all adjustments necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented. Results of interim periods should not be considered indicative of the results for the full year. These unaudited condensed consolidated interim financial statements include estimates and assumptions of management that affect the amounts reported in the unaudited condensed consolidated financial statements. Actual results could differ from these estimates. Changes in Presentation Certain prior year amounts have been restated to conform to the Company’s current reporting unit structure. Due to the sale of the Language Solutions business, the Company made changes to the reporting units within the U.S. segment. The former Language Solutions and other reporting unit has been renamed “Language Solutions.” Certain results previously included within the former Language Solutions and other reporting unit are now included within the Investment Markets reporting unit.

Revenue Recognition [Abstract]
Revenue	Note 2. Revenue Revenue Recognition The Company manages highly-customized data and materials, such as Exchange Act, Securities Act and Investment Company Act filings with the SEC on behalf of its customers, manages virtual data rooms and performs XBRL and related services. Clients are provided with EDGAR filing services, XBRL compliance services and translation, editing, interpreting, proof-reading and multilingual typesetting services, among others. The Company’s software-as-a-service solutions (“SaaS”) include the Venue Virtual Data Room, the FundSuiteArc software platform, ActiveDisclosure and data and analytics, among others. Substantially all of the Company’s revenue is derived from contracts with an initial expected duration of one year or less. Generally, customer payment is due within ten days upon invoicing. Revenue is recognized upon transfer of control of promised services or products to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services or products. The Company’s arrangements with customers often include promises to transfer multiple services or products to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately requires significant judgment. Certain customer arrangements have multiple performance obligations as certain promises are both capable of being distinct and are distinct within the context of the contract. Other customer arrangements have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, and therefore are not distinct. Revenue for the Company’s services and products is recognized either over time or at a point in time, as outlined below. Over time The Company recognizes revenue for certain services over time. • The Company’s SaaS solutions, including the Venue Virtual Data Room, the FundSuiteArc software platform, ActiveDisclosure, data and analytics and others, are generally provided on a subscription basis and allow customers access to use the products over the contract period. As a result, revenue for SaaS solutions are recognized ratably over time as the customer receives the benefit throughout the contract period. The timing of invoicing varies, however the customer may be invoiced before the end of the contract period, resulting in a deferred revenue balance. • Revenue for warehousing services are recognized ratably over time as the customer receives the benefit throughout the storage period. Point in time All remaining revenue arrangements are generally recognized at a point in time and are primarily invoiced upon completion of all services or upon shipment to the customer. • Certain of these arrangements include multiple performance obligations and revenue is recognized upon completion of each performance obligation, such as when a document is filed with a regulatory agency and upon completion of printing the related document. For arrangements with multiple performance obligations, the transaction price is allocated to the separate performance obligations. The Company provides customer specific solutions and as such, observable standalone selling price is rarely available. Standalone selling price is more frequently determined using an estimate of the standalone selling price of each distinct service or product, taking into consideration historical selling price by customer for each distinct service or product. These estimates may vary from the final amounts invoiced to the customer and are adjusted upon completion of all performance obligations. Customers may be invoiced subsequent to the recognition of revenue for completed performance obligations , resulting in contract asset balances. • Revenue for arrangements which include assisting customers in completing regulatory filings for transactions, such as mergers and acquisitions or other public capital market transactions, is recognized upon completion of all promises, including the services performed and printing of the related document, if applicable. • Revenue for arrangements without a regulatory filing generally have a single performance obligation, as the services and products provided are not distinct within the context of the contract, and are recognized upon completion of the services performed or upon completion of printing of the related product . • Warehousing, fulfillment services and shipping and handling are each separate performance obligations. As a result, when the Company provides warehousing and future fulfillment services, revenue for the composition services performed and printing of the product is recognized upon completion of the performance obligation(s), as control of the inventory has transferred to the customer and the inventory is being stored at the customer’s request. Because substantially all of the Company’s products are customized, product returns are not significant; however, the Company accrues for the estimated amount of customer credits at the time of sale. The Company records deferred revenue when amounts are invoiced but the revenue recognition criteria are not yet met. Such revenue is recognized when all criteria are subsequently met. Certain revenues earned by the Company require significant judgment to determine if revenue should be recorded gross, as a principal, or net of related costs, as an agent. Billings for shipping and handling costs as well as certain postage costs, and out-of-pocket expenses are recorded gross. Revenue is not recognized for customer-supplied postage. The Company’s printing operations process paper that may be supplied directly by customers or may be purchased by the Company from third parties and sold to customers. Revenue is not recognized for customer-supplied paper, however revenues for Company-supplied paper are recognized on a gross basis. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to authorities. Adoption of ASU 2014-09 In May 2014, the FASB issued Accounting Standards Update No. 2014-09 “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue using a five-step process that supersedes virtually all existing revenue guidance. ASU 2014-09 also requires additional quantitative and qualitative disclosures. On January 1, 2018, the Company adopted the standard and all related amendments, using the modified retrospective approach applied to contracts that were not completed as of January 1, 2018. The Company recognized the cumulative effect of applying the standard as an opening transition adjustment to retained earnings. The comparative periods have not been restated and continue to be reported under the accounting standards in effect for those periods (“Previous Revenue Standard”). As a result of the adoption of ASU 2014-09, revenue recognition has been accelerated for certain arrangements with multiple performance obligations as revenue is now recognized upon the completion of each performance obligation rather than upon completion of all services and shipment of the related document, if applicable. Revenue has also been accelerated for certain inventory which has been invoiced but not yet shipped at the customer’s request. Additionally, certain revenues related to virtual data room services have been deferred to be recognized over the term of the contract. As substantially all of the Company’s revenue is derived from contracts with an initial expected duration of one year or less, the Company has applied the practical expedient for performance obligations related to contracts with an initial duration of less than one year and is therefore not required to disclose information regarding remaining performance obligations at the end of the reporting period. The Company has also elected the practical expedient to recognize costs to obtain the contract, primarily commissions, as incurred. The cumulative effect of the changes made to the Company’s consolidated January 1, 2018 balance sheet for the adoption of ASU 2014-09 were as follows: Balance at December 31, 2017 Adoption of ASU 2014-09 Balance at January 1, 2018 Assets Receivables, less allowances for doubtful accounts $ 165.2 $ 8.9 $ 174.1 Inventories 23.3 (10.6 ) 12.7 Deferred income taxes 22.2 (0.5 ) 21.7 Total assets 893.5 (2.2 ) 891.3 Liabilities Accrued liabilities 119.2 (3.1 ) 116.1 Equity Retained earnings 8.9 0.9 9.8 Total liabilities and equity $ 893.5 $ (2.2 ) $ 891.3 The impact of the adoption of ASU 2014-09 on the Company’s condensed consolidated statement of operations for the three months and nine months ended September 30, 2018 and condensed consolidated balance sheet as of September 30, 2018 was as follows: Three Months Ended September 30, 2018 Previous Revenue Standard Adoption of ASU 2014-09 As Reported Services net sales $ 139.1 $ (0.6 ) $ 138.5 Products net sales 80.3 $ (1.9 ) 78.4 Total net sales 219.4 (2.5 ) 216.9 Services cost of sales (exclusive of depreciation and amortization) 75.5 — 75.5 Products costs of sales (exclusive of depreciation and amortization) 60.0 (2.2 ) 57.8 Total cost of sales 135.5 (2.2 ) 133.3 Selling, general and administrative expenses (exclusive of depreciation and amortization) 62.6 — 62.6 Income tax expense (benefit) 19.8 (0.1 ) 19.7 Net earnings $ 48.2 $ (0.2 ) $ 48.0 Earnings per share Basic 1.43 (0.01 ) 1.42 Diluted 1.41 (0.01 ) 1.40 Nine Months Ended September 30, 2018 Previous Revenue Standard Adoption of ASU 2014-09 As Reported Services net sales $ 484.9 $ 1.0 $ 485.9 Products net sales 278.6 (1.8 ) 276.8 Total net sales 763.5 (0.8 ) 762.7 Services cost of sales (exclusive of depreciation and amortization) 253.0 0.4 253.4 Products costs of sales (exclusive of depreciation and amortization) 205.0 (0.9 ) 204.1 Total cost of sales 458.0 (0.5 ) 457.5 Selling, general and administrative expenses (exclusive of depreciation and amortization) 203.8 — 203.8 Income tax expense (benefit) 31.6 (0.1 ) 31.5 Net earnings $ 74.8 $ (0.2 ) $ 74.6 Earnings per share Basic 2.22 (0.01 ) 2.21 Diluted 2.20 (0.01 ) 2.19 September 30, 2018 Previous Revenue Standard Adoption of ASU 2014-09 As Reported Assets Receivables, less allowances for doubtful accounts $ 215.7 $ 5.8 $ 221.5 Inventories 23.8 (10.0 ) 13.8 Deferred income taxes 14.5 (0.5 ) 14.0 Total assets 918.1 (4.7 ) 913.4 Liabilities Accrued liabilities 142.7 (5.4 ) 137.3 Equity Retained earnings 83.7 0.7 84.4 Total liabilities and equity $ 918.1 $ (4.7 ) $ 913.4 Disaggregation of revenue The following tables disaggregates revenue by reporting unit and timing of revenue recognition for the three and nine months ended September 30, 2018: Three Months Ended September 30, 2018 Point in time Over time Total U.S. Capital Markets $ 78.1 $ 24.4 $ 102.5 Investment Markets* 70.1 11.7 81.8 Language Solutions* 1.2 — 1.2 Total U.S. 149.4 36.1 185.5 International 26.7 4.7 31.4 Total net sales $ 176.1 $ 40.8 $ 216.9 Nine Months Ended September 30, 2018 Point in time Over time Total U.S. Capital Markets $ 292.1 $ 72.5 $ 364.6 Investment Markets* 224.2 38.6 262.8 Language Solutions* 13.7 — 13.7 Total U.S. 530.0 111.1 641.1 International 107.9 13.7 121.6 Total net sales $ 637.9 $ 124.8 $ 762.7 * Certain prior quarter amounts were restated to conform to the Company’s current reporting unit structure.

For the nine months ended September 30, 2017, the Company also recorded $0.2 million of net impairment charges primarily related to leasehold improvements associated with facility closures.

The other components of net periodic benefit cost are presented in the income statement separately from the line item(s) that includes the service cost and outside of any subtotal of operating income. ASU 2017-07 was adopted on a retrospective basis.

Income Tax Disclosure [Abstract]
Income Taxes	Note 10. Income Taxes The Company’s provision for income taxes for the three and nine months ended September 30, 2018 and 2017 is based on the estimated annual effective tax rate, plus discrete items. The following table presents the provision for income taxes and the effective income tax rates for the three and nine months ended September 30, 2018 and 2017: Three Months Ended September 30, 2018 2017 $ Change % Change (in millions, except percentages) Earnings before income taxes $ 67.7 $ 7.4 $ 60.3 814.9 % Income tax expense 19.7 2.1 17.6 838.1 % Effective income tax rate 29.1 % 28.4 % Nine Months Ended September 30, 2018 2017 $ Change % Change (in millions, except percentages) Earnings before income taxes $ 106.1 $ 55.4 $ 50.7 91.5 % Income tax expense 31.5 22.0 9.5 43.2 % Effective income tax rate 29.7 % 39.7 % Cash payments (net of refunds) for U.S. federal, states and foreign income taxes were $1.5 million and $8.9 million for the three months ended September 30, 2018 and 2017, respectively, and $7.6 million and $21.8 million for the nine months ended September 30, 2018 and 2017, respectively. The decrease in the effective income tax rate to 29.7% for the nine months ended September 30, 2018 compared to 39.7% for the nine months ended September 30, 2017 was primarily due to changes in U.S. corporate tax law pursuant to the enactment of the U.S. Federal Tax Cut and Jobs Act (“the Tax Act”) on December 22, 2017, and includes a reduction of the corporate income tax from 35% to 21%, partially offset by an increase in non-deductible expenses and the taxation of certain foreign earnings referred to in the Tax Act as global intangible low-taxed income. The effective income tax rate for the nine months ended September 30, 2018 also reflects the tax impact of the sale of the Language Solutions business. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, the Company made reasonable estimates of the tax effects and recorded provisional amounts in its consolidated financial statements for the year ended December 31, 2017. Staff Accounting Bulletin No. 118 (“SAB 118”) provided a measurement period of one year from the Tax Act enactment date for companies to complete their accounting for the enactment-date effects of the Tax Act that were considered provisional estimates at December 31, 2017. During the first quarter of 2018, the Company recognized a measurement-period adjustment of $0.4 million to decrease the income tax liability with a corresponding $0.4 million income tax benefit related to the one-time transition tax on foreign subsidiaries’ untaxed accumulated earnings. The Company is continuing to gather and review additional information needed to complete the accounting for the tax effects of the Tax Act. As a result, the Company has not made any additional measurement-period adjustments during the three months ended September 30, 2018 with respect to the one-time transition tax, re-measurement of deferred tax assets and liabilities and the Company’s indefinite reinvestment assertion. The Company will complete its accounting for these items within the prescribed measurement period.

Subsequent to the Separation, RRD and LSC are clients of the Company and expect to utilize SaaS solutions and services that the Company provides to all of its clients. Sublease Agreement In connection with the Separation, the Company assumed an operating lease through 2024 for the Company’s headquarters. There is a related non-cancelable sublease rental to RRD for the same period. The Company remains secondarily liable under this lease in the event that the sub-lessee defaults under the sublease terms. The Company does not believe that material payments will be required as a result of the secondary liability provisions of the primary lease agreement.

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	Note 18. New Accounting Pronouncements Recently Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, which outlines a single comprehensive model for entities to use in accounting for revenue using a five-step process that supersedes virtually all existing revenue guidance. ASU 2014-09 also requires additional quantitative and qualitative disclosures. In August 2015, the FASB issued Accounting Standards Update No. 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date” (“ASU 2015-14”), which deferred the effective date of ASU 2014-09 to January 1, 2018. The Company adopted the standard on January 1, 2018 using the modified retrospective approach. The Company recognized the cumulative effect of applying the standard as an opening transition adjustment to retained earnings. The comparative periods have not been restated and continue to be reported under the accounting standards in effect for those periods. Refer to Note 2, Revenue In March 2017, the FASB issued ASU 2017-07, which the Company adopted retrospectively in the first quarter of 2018. Refer to Note 9, Retirement Plans , for further information. Recently Issued Accounting Pronouncements In February 2018, the FASB issued Accounting Standards Update No. 2018-02 “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Income Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which provides entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the Tax Act to retained earnings. ASU 2018-02 may be applied either in the period of adoption or retrospectively to each period in which the effect of the Tax Act is recognized. ASU 2018-02 is effective in the first quarter of 2019. Early adoption is permitted. The Company is evaluating the impact of ASU 2018-02. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to put most leases on the balance sheet but recognize expense on the income statement in a manner similar to current accounting. For lessors, ASU 2016-02 also modifies the classification criteria and the accounting for sales-type and direct financing leases. The standard requires a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements and is effective in the first quarter of 2019. In July 2018, the FASB issued Accounting Standards Update 2018-11 (“ASU 2018-11”), which provides an optional transition method to apply ASU 2016-02 in the period of adoption and recognize a cumulative-effect opening transition adjustment to retained earnings, without applying the standard to comparative periods. ASU 2018-11 also provides lessors with a practical expedient to account for lease and associated non-lease components as a single component when certain criteria are met. Early adoption of ASU 2016-02 is permitted; however, the Company will adopt the standard in the first quarter of 2019 and plans to apply the optional transition method upon adoption. The Company is in the process of reviewing its existing lease portfolio, which is primarily comprised of real estate leases, to evaluate the impact of ASU 2016-02 on the consolidated financial statements. The Company currently expects to recognize a lease liability and corresponding right-of-use asset for substantially all operating lease agreements, which will have a significant impact on the Company’s consolidated balance sheet. The Company currently plans to elect the optional package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs and therefore, does not expect the adoption of ASU 2016-02 to have a significant impact on the consolidated statement of operations for existing operating leases. The ultimate impact of the standard will depend on the Company’s lease portfolio at the date of adoption. Additionally, the Company is evaluating the processes and internal controls needed to support the changes resulting from the new lease accounting standard.

Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition The Company manages highly-customized data and materials, such as Exchange Act, Securities Act and Investment Company Act filings with the SEC on behalf of its customers, manages virtual data rooms and performs XBRL and related services. Clients are provided with EDGAR filing services, XBRL compliance services and translation, editing, interpreting, proof-reading and multilingual typesetting services, among others. The Company’s software-as-a-service solutions (“SaaS”) include the Venue Virtual Data Room, the FundSuiteArc software platform, ActiveDisclosure and data and analytics, among others. Substantially all of the Company’s revenue is derived from contracts with an initial expected duration of one year or less. Generally, customer payment is due within ten days upon invoicing. Revenue is recognized upon transfer of control of promised services or products to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services or products. The Company’s arrangements with customers often include promises to transfer multiple services or products to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately requires significant judgment. Certain customer arrangements have multiple performance obligations as certain promises are both capable of being distinct and are distinct within the context of the contract. Other customer arrangements have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, and therefore are not distinct. Revenue for the Company’s services and products is recognized either over time or at a point in time, as outlined below. Over time The Company recognizes revenue for certain services over time. • The Company’s SaaS solutions, including the Venue Virtual Data Room, the FundSuiteArc software platform, ActiveDisclosure, data and analytics and others, are generally provided on a subscription basis and allow customers access to use the products over the contract period. As a result, revenue for SaaS solutions are recognized ratably over time as the customer receives the benefit throughout the contract period. The timing of invoicing varies, however the customer may be invoiced before the end of the contract period, resulting in a deferred revenue balance. • Revenue for warehousing services are recognized ratably over time as the customer receives the benefit throughout the storage period. Point in time All remaining revenue arrangements are generally recognized at a point in time and are primarily invoiced upon completion of all services or upon shipment to the customer. • Certain of these arrangements include multiple performance obligations and revenue is recognized upon completion of each performance obligation, such as when a document is filed with a regulatory agency and upon completion of printing the related document. For arrangements with multiple performance obligations, the transaction price is allocated to the separate performance obligations. The Company provides customer specific solutions and as such, observable standalone selling price is rarely available. Standalone selling price is more frequently determined using an estimate of the standalone selling price of each distinct service or product, taking into consideration historical selling price by customer for each distinct service or product. These estimates may vary from the final amounts invoiced to the customer and are adjusted upon completion of all performance obligations. Customers may be invoiced subsequent to the recognition of revenue for completed performance obligations , resulting in contract asset balances. • Revenue for arrangements which include assisting customers in completing regulatory filings for transactions, such as mergers and acquisitions or other public capital market transactions, is recognized upon completion of all promises, including the services performed and printing of the related document, if applicable. • Revenue for arrangements without a regulatory filing generally have a single performance obligation, as the services and products provided are not distinct within the context of the contract, and are recognized upon completion of the services performed or upon completion of printing of the related product . • Warehousing, fulfillment services and shipping and handling are each separate performance obligations. As a result, when the Company provides warehousing and future fulfillment services, revenue for the composition services performed and printing of the product is recognized upon completion of the performance obligation(s), as control of the inventory has transferred to the customer and the inventory is being stored at the customer’s request. Because substantially all of the Company’s products are customized, product returns are not significant; however, the Company accrues for the estimated amount of customer credits at the time of sale. The Company records deferred revenue when amounts are invoiced but the revenue recognition criteria are not yet met. Such revenue is recognized when all criteria are subsequently met. Certain revenues earned by the Company require significant judgment to determine if revenue should be recorded gross, as a principal, or net of related costs, as an agent. Billings for shipping and handling costs as well as certain postage costs, and out-of-pocket expenses are recorded gross. Revenue is not recognized for customer-supplied postage. The Company’s printing operations process paper that may be supplied directly by customers or may be purchased by the Company from third parties and sold to customers. Revenue is not recognized for customer-supplied paper, however revenues for Company-supplied paper are recognized on a gross basis. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to authorities.
