ABSTRACT:
There are disclosed methods and systems for the process of on-press plate imaging, including automatic processes for plate preparation, that compensate for registration and print-length errors (plate loading is performed before imaging). As a result of these processes, the position accuracy is determined by the imaging system. The system of the present invention creates deformed images on the plates during the imaging stage, these deformed images, being such that the separations will be in register (coordinated) after printing.
