Item 3. Source and Amount of Funds or Other Consideration.

In July 2010, Catalyst Fund Limited Partnership II received 2,662,737 shares of the Class A Common Stock in connection with the Company’s acquisition of World Color Press Inc. (f/k/a Quebecor World (USA) Inc.), pursuant to the Reporting Persons’ former shareholdings in World Color Press Inc.

The Reporting Persons expended an aggregate of approximately $33,000 of working capital to purchase an additional 2,137 shares of Class A Common Stock in October 2011. Such transaction was effected in an open market purchase.

10

CUSIP No. 747301109 Page 11 of 15 Pages

Item 4. Purpose of Transaction.

The Reporting Persons are long-term shareholders of the Company. The Reporting Persons view the Company as a superior, low-cost operator with tremendous potential and believe in the Company’s long-term prospects and value proposition.

However, the Reporting Persons believe that due to severe, ongoing mismanagement, the Company’s stock is substantially undervalued. As a result, the Reporting Persons have engaged, and expect to continue to engage, in discussions with management, the board of directors, other stakeholders of the Company and other relevant parties concerning the business, operations, management, strategy and future plans of the Company. These discussions have been based on publicly available information and, in such discussions, the Reporting Persons have not received any material non-public information about the Company, or otherwise. Through these discussions, the Reporting Persons have shared their concerns and recommended that the Company take certain actions to address these concerns in ways that will maximize shareholder value.

The Reporting Persons have made clear to the Company that they believe it needs to (i) communicate better with analysts and investors, in order to rebuild credibility with “the street” and avoid its stock becoming an “orphan” stock; (ii) clarify its strategy and provide greater financial transparency; and (iii) transform its focus, governance and culture from a private to a public company mentality. The Reporting Persons have conveyed to the Company how they believe the Company has failed in its approach to communicating with analysts and its investors, and have offered suggestions about how to correct this fundamental flaw. The Reporting Persons believe that these suggestions have been ignored to the detriment of investors and the Company’s stock price. The Company’s inability to communicate effectively with the market was highlighted in the recently completed fiscal year, when the Company had to significantly lower its earnings estimates in two consecutive quarters and the Company lost over 66% of its equity value from December 31, 2010 to March 30, 2012. As a consequence, the Reporting Persons believe that the Company’s financial and investor relations functions are broken and need to be fixed. The Reporting Persons believe, and have indicated to the Company, that the Company’s weakness in this area is compelling enough to warrant the replacement of its Chief Financial Officer with someone with more public company savvy and the services of an additional, independent director with demonstrated capital markets experience and investor relations strengths.

In addition to improving its inadequate communications strategy, the Reporting Persons believe the Company must better leverage its financial resources to maximize shareholder value. Accordingly, the Reporting Persons have also urged the Company not to invest in additional businesses until its stock price improves. This urging was ignored by the Company, as it recently purchased a specialty printer in the U.S., exchanged its Canadian assets with Transcontinental’s Mexican assets, and purchased a minority interest in a print solutions company in India. Furthermore, the Company has failed to provide adequate information regarding the terms of these transactions or the profitability of these companies.

11

CUSIP No. 747301109 Page 12 of 15 Pages

Catalyst has also urged the Company to significantly increase its dividend and stock buyback efforts. These suggestions, too, have been to no avail. To be clear, the Reporting Persons believe that the Company’s recently announced increase of its quarterly cash dividend by 25% to $0.25 per share is insufficient.

The Reporting Persons expect to continue to engage in discussions with the Company and other concerned stakeholders about these and related matters. The Reporting Person may also make proposals to the board, seek to change the composition of, or seek representation on, the board, or engage in other activities, all with the underlying purpose of increasing shareholder value.

Except as described herein, the Reporting Persons have no present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons intend to review their investment in the Company on a continuing basis. Depending on various factors including, without limitation, the Company’s financial position and strategic direction, the outcome of the discussions referenced above, actions taken by management and the board of directors, price levels and trading activity of the Company’s stock, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Company as they deem appropriate for investment purposes and/or to change or influence the control of the Company, including, without limitation, (i) acquiring additional common stock and/or other equity, debt, notes, instruments or other securities (collectively, “Securities”) of the Company in the open market or otherwise; (ii) disposing of any or all of their Securities in the open market or otherwise; (iii) engaging in short selling of or any hedging or similar transactions with respect to the Securities; and/or (iv) otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

(a) Catalyst Fund Limited Partnership II (and Catalyst Fund General Partner II Inc., CCGI Holdings II Inc., The Catalyst Capital Group Inc., Newton Glassman, Gabriel de Alba and Jonathan A. Levin through the Catalyst Fund Limited Partnership II) beneficially own 2,664,874 shares of Class A Common Stock. The shares of Class A Common Stock presently held by Catalyst Fund Limited Partnership II represent approximately 8.1% of the issued and outstanding shares of Class A Common Stock of the Company, based upon the 32,725,759 shares of Class A Common Stock issued and outstanding as reported in the Company’s Form 10-K for the fiscal year ended December 31, 2011, filed with the SEC on February 29, 2012.

Pursuant to Rule 13d-3(d)(1)(i) the number of issued and outstanding shares of Class A Common Stock assumes that each other shareholder of the Company does not exercise or convert any other rights, warrants, options or securities exercisable or convertible into Class A Common Stock within 60 days of the date of this report.
