CA 1325922

A B S T R A C T The invention relates to a printing unit for rotary printing presses with inking unit and damping unit as well as with at least two ink-conducting cylinders, such as plate cylinder and rubber-covered cylinder. According to the invention, such a printing unit is intended virtually to eliminate the printing of waste when the unit is being set to a state suitable for a production run. The object of the invention is achieved in that one or more ink-conducting cylinders are assigned an engageable and disengageable inking-reducing unit, said inking- reducing unit removing from the ink-conducting cylinder approximately the same part of the ink and damping- solution film that would otherwise have been removed by the paper as it passes through.
