PHOTOPOLYMER PRINTING FORM WITH REDUCED PROCESSING TIME

摘要

The present invention is directed to an improved method of producing photosensitive printing plate blanks comprising the steps of: a) forming a first photocurable layer on a backing sheet; b) curing the first photocurable layer with actinic radiation to create a hard floor layer throughout the first photocurable layer; and c) forming a second photocurable layer on top of the cured first photocured layer that is processible by actinic radiation to form a relief image printing element. The printing plate blank having the precured floor layer may then be delivered to a print shop customer for further processing to produce a relief image printing element.
