Abstract
The present invention is directed to a web fed rotary printing press which can perform a printing plate change on the fly, while preventing the printing plate from touching an associated moving blanket cylinder. In accordance with exemplary embodiments, a nip roller is used to securely press the printing plate toward the plate cylinder during printing plate replacement, such that only a small gap exists between the stopped plate cylinder and the moving blanket cylinder. As such, the entire printing unit need not be modified to account for ink train cylinder movement.
