Method of making a photopolymer sleeve blank for flexographic printing

摘要

A method of making a photopolymer sleeve blank is provided which includes providing a base sleeve, applying a cushion layer over the base sleeve, and applying a first photopolymer layer over the cushion layer. The exterior-facing surface of the first photopolymer layer is exposed to a curing source, followed by the application of a second, uncured photopolymer layer over the first photopolymer layer. The first photopolymer layer is preferably ground to a predetermined thickness either before or after exposure to the curing source to provide a preferred floor dimension. The resulting photopolymer sleeve blank has a uniform floor which can be readily imaged and processed by conventional equipment used in the flexographic printing industry.
