Abstract
A method of thermally developing photocurable printing blank to produce a relief pattern comprising a plurality of relief dots. The photocurable printing blank comprises a backing layer having at least one photocurable layer disposed thereon and a laser ablatable mask layer disposed on top of the at least one photocurable layer. The method includes the steps of (1) imaging the at least one photocurable layer by ablating portions of the laser ablatable mask layer; (2) laminating an oxygen barrier membrane to a top of the laser ablated mask layer; (3) exposing the printing blank to actinic radiation through the oxygen barrier membrane and mask layer to actinic radiation, thereby creating the relief pattern; (4) removing the oxygen barrier membrane; and (5) thermally developing the printing blank to remove the laser ablated mask layer and uncured portions of the photocurable layer and reveal the relief pattern. The presence of the oxygen harrier membrane produces printing dots having desired characteristics.
