Abstract:
A process for preparing a printing plate, comprising the steps of:(a) exposing a photopolymer printing plate to a source of actinic radiation, wherein said actinic radiation causes said photopolymer to change at least one of its physical properties, thereby forming an exposed photopolymer printing plate, (b) removing a portion of said photopolymer from said exposed photopolymer printing plate by contacting said photopolymer printing plate with a developer, thereby forming a developed photopolymer printing plate, (c) rinsing said plate with an aqueous solvent to remove said developer, and (d) irradiating said developed photopolymer printing plate with deep ultraviolet radiation with a wavelength of from about 170 to about 290 nanometers.
