Abstract: Thermally developing a 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: (1 ) imaging a photo curable layer by ablating the mask layer to create the relief pattern; (2) laminating an oxygen barrier membrane atop the ablated mask layer; (3) exposing the printing blank to actinic radiation through the oxygen barrier membrane and ablated mask layer to selectively crosslink and cure portions of the photocurable layer, thereby creating the relief pattern; (4) removing the oxygen barrier membrane from atop the ablated mask layer; and (5) thermally developing the printing blank to remove the ablated mask layer and uncured portions of the photo curable layer and reveal the relief pattern.

Abstract: A method of thermally developing a 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 the laser ablatable mask layer to create the relief pattern on the surface of the at least one photocurable 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 one or more sources of actinic radiation 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 mask layer, thereby creating the relief pattern; (4) removing the oxygen barrier membrane from the top of the laser ablated mask layer; 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 barrier membrane produces printing dots having desired characteristics. The method can also be used with an analog platemaking process that uses a negative instead of an ablatable mask layer, or, in the alternative, the negative itself can be used as the oxygen barrier layer.

Abstract: A method of thermally developing a photocurable printing blank to produce a relief image comprising a plurality of relief dots is provided. The photocurable printing blank comprises a backing layer having at least one photocurable layer disposed thereon. The method includes the steps of (1) laminating an oxygen barrier membrane to a top of the photocurable layer; (2) placing a negative of the desired relief image on top of the oxygen barrier membrane; (3) exposing the printing blank to actinic radiation through the oxygen barrier and negative to crosslink and cure portions of the at least one photocurable layer, creating the relief pattern; (4) removing the oxygen barrier membrane and negative from the top of the at least one photocurable layer; and (5) developing the printing blank to reveal the relief image. The presence of the oxygen barrier membrane produces dots having desired characteristics. The negative itself can be used as the oxygen barrier layer.
