Abstract

Method of influencing ink-trapping behavior of ink-conducting components of a printing unit in a rotary printing press includes disconnecting at a clutch location an inking-unit drive coming from printing-unit cylinders, directly imaging a printing form on a printing-form cylinder within the rotary printing press, and reestablishing the drive connection between the inking unit and the printing-unit cylinders at the clutch location after completing the direct imaging of the printing form; and device for performing the method.
