Abstract

A method for changing printing plates in rotary printing presses, including a plurality of printing units each having a plate cylinder and a dedicated drive for driving the plate cylinder independently of an associated blanket cylinder in a respective printing unit, includes moving the respective blanket cylinder at a somewhat higher circumferential speed than the associated plate cylinder while conveying one or more printing plates out of the printing unit, at least in one operating mode, during a plate changing operation. A printing press and a controller are also provided.
