Abstract

Following imagewise exposure of a sandwiched photopolymer layer, the outer layers between which the photopolymer is interposed are separated in a manner that leaves some photopolymer on each of the separated layers. The photopolymer remaining on one layer contains the raised pattern that will carry ink, and may be subjected to further exposure to actinic radiation in order to complete the curing process without the need for washing; the photopolymer remaining on the other layer can be removed and reused. As a result, waste is minimized or eliminated.
