Plate for digitally-imaged offset printing

摘要

A plateless process for offset lithographic printing using an inexpensive imaging system and using the surface of a lithographic printing cylinder itself as a plate substrate. The process enables production of a simple and inexpensive offset lithographic printing plate for use in an offset printing system, with the plate being produced by coating the substrate of the printing plate with a photosensitive liquid coating, and sealing the coated substrate with a release coating, coated on a protective film.
