ABSTRACT:
The present invention is directed to an image plate comprised of a stiffening layer formed from a first photocured polymeric material and a print contact layer formed from a second photocured polymeric material wherein the first photocured polymeric material is a hard photocured polymeric material and the second photocured polymeric material is formed from a soft photocured polymeric material. The image plate is assembled as a photocured pre-cut sheet of relief images comprising a first layer formed from a releasable substrate, a second layer formed from a first photocured polymer, and a third layer formed from a second photocured polymer, wherein the first photocured polymer is formed from a hard photopolymer resin and the second photocured polymer is formed from a soft photopolymer resin. The method of forming releasable image plate is also disclosed which includes selectively photocuring a first and second liquid photosensitive material to form the releasable photocured image plate via light transmitted from a first light source through an image bearing negative and light transmitted from a second light source through a blank forming negative.
