Abstract

An offset printing press with an inking unit and a wetting unit which correspond to a plate cylinder, with at least one intermediate roller which connects the inking and wetting units. The intermediate roller is bilaterally mounted on bearings and can be adjusted by an actuator device with respect to an inking and/or a wetting roller. The stenciling on the inking roller is reduced during separate operation between the inking unit and the wetting unit by having the intermediate roller remain in contact with the inking roller when the intermediate roller is disengaged from the wetting roller.
