Abstract
An inkjet printer is used to apply an ink that is substantially opaque to actinic radiation in at least one wavelength region effective to cure the photosensitive printing plate to the edges and corners, of a printing plate after the plate has been trimmed (i.e., cut) to a suitable size and shape for mounting on a printing sleeve or cylinder. Use of inkjet printing allows for the cut surfaces of the plate to quickly and accurately be coated with a UV-opaque ink and prevents, or substantially eliminates, undesirable curing of cut surfaces of a photosensitive printing plate. The ink covers the photocurable surfaces exposed by the cutting process and prevents the cut surfaces of the printing plate from undesirably curing until proper exposure and development of the printing plate.
