  • SYSTEM AND METHOD FOR EXPOSING A DIGITAL POLYMER PLATE
    Publication number: 20150336370
    Abstract: 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.

  • Apparatus and method using a UV light collimator to expose a photopolymer plate
    Patent number: 6766740
    Abstract: A combination of components and method for collimating ultraviolet light to exposed a photopolymer plate. A polarizing filter is positioned between an ultraviolet light source and a photopolymer plate. The film or other media having the image to be transferred is likewise positioned between the ultraviolet light source and the photopolymer plate. Rays of light are filtered to allow only the passage of rays perpendicular to the outward-facing surface of the photopolymer plate.
