Abstract
The invention relates to a process and apparatus for forming a photopolymerizable element useful as a flexographic printing plate having at least one layer of particulate material. The process includes forming a layer of a molten photopolymerizable material onto a support; and applying the particulate material onto an exterior surface of the photopolymerizable layer opposite the support within 48 hours of forming the layer of photopolymerizable material. The process optionally includes heating of the surface of the photopolymerizable layer.

A process for forming a photopolymerizable element useful as a flexographic printing plate having at least one layer of particulate material comprising:
- forming a layer from a molten photopolymerizable material onto a support;
- and
- applying the particulate material onto an exterior surface of the photopolymerizable layer opposite the support within 48 hours of forming the layer of photopolymerizable material.
A process for forming a photopolymerizable element useful as a flexographic printing plate having at least one layer of particulate material comprising:
- forming a layer from a molten photopolymerizable material onto a support;
- and
- applying the particulate material onto an exterior surface of the photopolymerizable layer opposite the support within 48 hours of forming the layer of photopolymerizable material and when the surface of photopolymerizable layer has a temperature greater than 30° C.
