Abstract
A printing group of a printing press is comprised of a transfer cylinder, a forme cylinder and a first roller of an inking unit. That first inking unit roller cooperates, as an ink application roller, with the forme cylinder. The inking unit is provided with two axially traversing friction cylinders which are serially disposed in the ink path to the forme cylinder. The first inking unit roller has substantially the same diameter as the forme cylinder.

1-53. (canceled)
A printing unit of a web-fed rotary printing press comprising:
- a first transfer cylinder having a first transfer cylinder axis of rotation;
- a first forme cylinder cooperating with said first transfer cylinder, said first forme cylinder having a first forme cylinder axis of rotation and a first forme cylinder diameter;
- a first inking unit including a first ink forme roller having a first ink forme roller axis of rotation and a first ink forme roller diameter and cooperating with said first forme cylinder, said first ink forme roller diameter being the same as said first forme cylinder diameter;
- a first ink supply in said first inking unit;
- first and second axially oscillating ink distribution cylinders arranged in series in an inking path between said first ink supply and said first ink forme roller, said first transfer cylinder, said first forme cylinder and said first inking unit forming a first printing couple;
- a second transfer cylinder having a second transfer cylinder axis of rotation;
- a second forme cylinder cooperating with said second transfer cylinder, said second forme cylinder having a second forme cylinder axis of rotation and a second forme cylinder diameter;
- a second inking unit including a second ink forme roller having a second ink forme roller axis of rotation and a second ink forme roller diameter and cooperating with said second forme cylinder, said second ink forme roller diameter being the same as each said forme cylinder diameter;
- a second ink supply in said second inking unit;
- and
- third and fourth axially oscillating ink distribution cylinders arranged in series in an inking path between said second ink supply and said second ink forme roller, said second transfer cylinder, said second forme cylinder and said second inking unit forming a second printing couple, said first transfer cylinder and said second transfer cylinder cooperating, said first printing couple and said second printing couple forming a blanket-to-blanket printing unit.
