        consideration, the sufficiency and receipt of which are
        hereby acknowledged, the undersigned hereby constitutes
        and appoints Jennifer J. Kent, Sherilyn R. Whitmoyer
        and Russell E. Ryba, and any of her or his substitutes,
        signing singly, the undersigned's true and lawful
        attorney-in-fact to:

       (1) execute for and on behalf of the undersigned (in accordance
       with Section 16(a) of the Securities Exchange Act of 1934,
       as amended, and the rules thereunder (the "Exchange Act")),
       any and all Forms 3, 4 and/or 5, and any amendments thereto,
       that are necessary or advisable for the undersigned to file
       under Section 16(a) (collectively, "Documents") with respect
       to the undersigned's holdings of and transactions in the
       securities issued by Quad/Graphics, Inc., a Wisconsin
       corporation (the "Company").

       (2) do and perform any and all acts for and on behalf of
       the undersigned that may be necessary or desirable to
       complete and execute any such Documents and timely file
       such Documents with the United States Securities and
       Exchange Commission and any stock exchange or similar authority; and

       (3) take any other action of any type whatsoever in connection
       with the foregoing which, in the opinion of such attorney-in-fact,
       may be of benefit to, in the best interest of, or legally required by,
       the undersigned, it being understood that the documents executed
       by such attorney-in-fact on behalf of the undersigned pursuant
       to this Power of Attorney shall be in such form and shall contain
       such terms and conditions as such attorney-in-fact may approve in such
       attorney-in-fact's discretion.

       The undersigned hereby grants to each such attorney-in-fact full power
       and authority to do and perform any and every act and thing whatsoever
       requisite, necessary or proper to be done in the exercise of any of the
       rights and powers herein granted, as fully to all intents and purposes
       as the undersigned might or could do if personally present, with
       full power of substitution or revocation, hereby ratifying and
       confirming all that each such attorney-in-fact (or such
       attorney-in-fact's substitute or substitutes) shall lawfully do or
       cause to be done by virtue of this power of attorney and the rights
       and powers herein granted. The undersigned acknowledges that each
       attorney-in-fact, in serving in such capacity at the request of
       the undersigned, is not assuming, nor is such attorney-in-fact's
       substitute or substitutes or the Company assuming, any of the
       undersigned's responsibilities to comply with the Exchange Act.

       The undersigned agrees that such attorney-in-fact may rely entirely
       on information furnished  orally or in writing by the undersigned to
       such attorney-in-fact. The undersigned also agrees to indemnify and
       hold harmless the Company and such attorney-in-fact against any losses,
      claims, damages or liabilities (or actions in  these respects) that
      arise out of or are based on any untrue statement or omission of
      necessary facts in the information provided by the undersigned to
      such attorney-in-fact for purposes of executing, acknowledging,
      delivering and filing Documents and agrees to reimburse the Company
      and such attorney-in-fact for any legal or other expenses reasonably
      incurred in connection with investigating or defending against any
      such loss, claim, damage, liability or action.

      This Power of Attorney shall remain in full force and effect until
      the undersigned is no longer required to file Documents with respect
      to the undersigned's holdings of and transactions in securities
      issued by the Company, unless earlier revoked by the undersigned
      in a signed writing delivered to each of the foregoing
      attorneys-in-fact.

      IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney
      to be executed as of this 17th day of May 2018.
