Abstract
A printing press comprises a frame. A plate cylinder is mounted in the frame for rotation about a first axis and a blanket cylinder is mounted in the frame for rotation about a second axis. The plate cylinder and the blanket cylinder have a contact pressure therebetween for printing operation. A skew eccentric is supported by the frame and is associated with at least one end of the plate cylinder. The skew eccentric is operable to change the relative angular positions of said first and second axes. A means is connected with said skew eccentric for maintaining the contact pressure between the plate cylinder and the blanket cylinder substantially unchanged upon rotation of the skew eccentric.
