Abstract

Creating one or more printing plate segments includes exposing a printing plate segment with imaging data to form an imaged plate segment, and marking the floor of the printing plate segment or the back of the printing plate segment with one or more registration marks according to marking data. The registration marks can be within the design area defined by the imaging data marked such that the registration marks are not visible on a print made from the imaged plate segment. Printing using positioned and mounted so-marked imaged plate segments produces a print without the registration marks visible on the print. Such plate segments can be unmounted and reused with the registration marks intact.
