Abstract

A method of developing a photocurable printing blank to produce a relief pattern comprising a plurality of relief dots having desired characteristics. The photocurable printing blank comprises a backing layer having at least one photocurable layer disposed thereon and a barrier layer disposed on the at least one photocurable layer. The method includes the steps of (1) placing a negative of a desired relief image on top of the barrier layer; (2) exposing the printing blank to actinic radiation through the barrier layer and negative to selectively crosslink and cure portions of the at least one photocurable layer, wherein the at least one photocurable layer is crosslinked and cured in the portions not covered by the negative, thereby creating the relief pattern; and (3) developing the printing blank to remove the barrier layer and uncured portions of the photocurable layer and reveal the relief pattern.
