Plate material that is photosensitive and upon exposure, its compounds polymerize to form a tough, abrasion resistant surface which becomes the inking media.
A specialized plastic with photosensitive coating which is masked and photoetched to create tactile graphics. Used primarily for A.D.A. signage requiring tactile copy and Braille.
A light sensitive high molecular weight compound consisting of up to millions of repeated linked units. Photopolymer material is used to make printing plates via negatives and computer generated images.
a light-sensitive polymer or plastic used either as a coating for litho plates or as a relief printing plate in its own right for letterpress or flexo, in which case it may have the non-image areas developed away by a solution of alcohol.
Material systems which change from a liquid to a solid state upon application of light (actinic) radiation. Light sources can be a laser or lamp, but related radiation-curable materials may be made solid by application of microwave or heat-based radiation sources. Photopolymers are typically complex mixtures of compounds rather than consisting of a single component.
A specialized plastic with a photosensitive coating that is masked and photo-etched to create tactile graphics. Used primarily for ADA signage that requires tactile copy and Braille.
Polymer that is sensitive to U.V. light. Used in temporary etched plates. Known then as Photopolymer Plates. Also one of the chemistries used in stencil emulsions. I.e. SBQ Photopolymer
