Abstract
A press contains an oscillating doctor and a motor for driving the oscillating doctor axially. The press further has at least one oscillating roller (ink distributor roller and/or damping solution distributor roller) and an oscillating mechanism, via which the oscillating roller is connected to the motor such that the oscillating roller and the oscillating doctor can be driven axially together by the motor.
