SYSTEM AND METHOD FOR EXPOSING A DIGITAL POLYMER PLATE

摘要

An improved process for producing flexographic printing plates using a digital workflow is described. After creating an in-situ digital mask over the photopolymerizable layer, the photopolymerizable layer is exposed to actinic radiation through the mask layer in a reduced oxygen environment. After subsequent development, the resulting relief printing form is composed of flat topped dots with crisp edges and steep bevel angles that can be used to print directly on corrugated materials.
