Abstract
A process for preparing a printing plate. In this process a photopolymer printing plate is exposed to a source of actinic radiation, and this exposure causes the photopolymer to change at least one of its physical properties. Thereafter, a portion of the photopolymer is removed. The developed printing plate is then irradiated with deep ultraviolet radiation with a wavelength of from about 170 to about 290 nanometers.

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, thereby forming a developed photopolymer printing plate, and
- (c) irradiating said developed photopolymer printing plate with deep ultraviolet radiation with a wavelength of from about 170 to about 290 nanometers.
