摘要

A printing unit includes a plate cylinder, a blanket cylinder for printing a first side of a web of material, and an inker with a plurality of inker rollers for inking the plate cylinder. The inker is 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. At least one of the plurality of inker rollers is adjustable as a function of a diameter of the plate cylinder when the inker is in the inactive position.
