Abstract
A printing unit includes a plate cylinder, a blanket cylinder for printing a first side of a web of material, and an inker for inking the plate cylinder, the inker being movable between an active position and an inactive position, the inker contacting the plate cylinder in the active position and the inker being separated from the plate cylinder in the inactive position. A plate operation unit such as a direct imaging device or a plate exchanger is movable into the active position of the inker when the inker is in the inactive position.
