Abstract
A method of selectively exposing a liquid photopolymer printing blank to actinic radiation to create a relief image printing plate. The printing blank is produced by (i) placing a photographic negative on a bottom glass platen and placing a coverfilm over the negative, (ii) disposing a layer of liquid photopolymer on top of the coverfilm and negative, and (iii) placing a backing sheet over the liquid photopolymer layer. The method includes the steps of scanning a light bar across an upper surface of the liquid photopolymer printing blank through the backing sheet to cure the layer of liquid photopolymer in selected areas, creating islands of cured polymer adjacent to the backing sheet, and imaging the photopolymer through the bottom of the liquid photopolymer printing blank to crosslink and cure selective portions of the liquid photopolymer and create a relief image therein. The relief image is created on the cured islands.
