PROCESS FOR PREPARING WATERLESS LITHOGRAPHIC PRINTING MASTERS BY INK JET PRINTING MEANS

摘要

ABSTRACT OF THE DISCLOSUREA master is provided by depositing a silicone or othermaterial which can be rendered ink releasing on a suitable sub-strate by means of an ink jet printing apparatus, and curing thesilicone to an elastomeric ink releasing condition. Alternatively,an ink jet printing apparatus can be employed to deposit inimage configuration, a catalyst to an uncured silicone on amaster substrate, a photopolymer to a cured silicone on amaster substrate which photopolymer can be cured to combinewith the silicone, or an imaging light insensitive shadowfluid to a light sensitive curable silicone coated on a mastersubstrate whereby the background nonimaged areas can be curedand the shadow fluid and underlying silicone removed to revealthe ink accepting substrate.
