Abstract
A doctor blade bar for a short inking unit employs an eccentric disk to engage an abutment on a doctor blade holder to retract a doctor blade that is held by the holder and a cooperating doctor blade guide into a retracted position with respect to a screen roller, Disengagement of the eccentric disk from the abutment allows the doctor blade to be moved by a pressure spring into contact with the screen roller.
