Abstract:
1. A printing couple of a web-fed rotary printing press, comprising a transfer cylinder ( 06 ), a forme cylinder ( 07 ), a roller ( 41 ) which roller ( 41 ) cooperates with the forme cylinder ( 07 ) as a dampening forme roller ( 41 ) of a dampening unit ( 09 ), and a single roller ( 28 ) of an inking unit ( 08 ), wherein said single roller ( 28 ) of the inking unit cooperates with the forme cylinder ( 07 ) as a single ink forme roller ( 28 ) which contacts the forme cylinder, wherein the inking unit ( 08 ) is configured with two axially oscillating distribution cylinders ( 33 ; 33 ′), arranged in series in an inking path between an ink supply system of the inking unit and the forme cylinder ( 07 ), wherein the rotational axes of the forme cylinder ( 07 ) and of the allocated transfer cylinder ( 06 ), when their rotational axes are in an operational position, define a plane (E), and wherein two of the printing couples ( 04 ), consisting of two cooperating transfer cylinders ( 06 ) and two allocated forme cylinders ( 07 ), together form a blanket-to-blanket printing unit ( 03 ), characterized in that the single ink forme roller ( 28 ) has substantially the same diameter as the cooperating forme cylinder ( 07 ), that, in the operational position, a plane (A) through the rotational axes of the single ink forme roller ( 28 ) and of the forme cylinder ( 07 ) forms a maximum angle δ of 15° with the plane (E) through the rotational axes of the cooperating forme cylinder ( 07 ) and the transfer cylinder ( 06 ) and that the single ink forme roller is rotationally driven by an ink forme roller drive motor that is independent of the forme cylinder.
