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.
