Abstract

A rotary printing press includes a laser beam imaging device to enable a rotary printing member to be prepared while it is located in the printing press. This arrangement has particular advantages when it is used with a lithographic or a gravure printing press and especially when used as a proofing press for color lithography or color gravure.
