FLEXOGRAPHY PRINTING PLATE, ITS MANUFACTURE AND LAMINATED BOARD USED FOR ITS MANUFACTURE

摘要

The present invention relates to flexographic printing plates, methods of their production and laminates for use in their production. A flexographic printing plate comprises a layer of a grindable elastomer (1) having a thickness up to 1000 microns firmly bonded to a support layer (3). A layer of photopolymerised elastomeric material (5) is firmly bonded onto the face of the support layer (3) away from the grindable elastomer (1). The photopolymerised material (5) is produced by exposure of a photopolymerisable liquid to actinic radiation. The support layer (3) may be omitted, and anchor layer(s) (2, 4) may be included. The plate may be ground to uniform thickness.
