Abstract: A photocurable printing blank comprises a backing layer having a photocurable layer disposed thereon, a barrier layer disposed on the photocurable layer, and a laser ablatable mask layer disposed on top of the barrier layer. The method includes the steps of (1 ) imaging the at least one photo curable layer by ablating the laser ablatable mask layer to create the relief pattern on the photocurable printing blank; (2) exposing the printing blank to actinic radiation through the barrier layer and mask layer to selectively crosslink portions of the photocurable layer, thereby creating the relief pattern; (3) developing the printing blank to remove the barrier layer, the laser ablated mask layer and uncured portions of the photo curable layer and reveal the relief pattern. The method can also be used with an analog platemaking process that uses a negative instead of an ablatable mask 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.

Abstract: A method of making a relief image printing element from a photosensitive printing blank is provided. A photosensitive printing blank with a laser ablatable layer disposed on at least one photocurable layer is ablated with a laser to create an In situ mask. The printing blank is then exposed to at least one source of actinic radiation through the in situ mask to selectively cross link and cure portions of the photocurable layer. Diffusion of air into the at least one photocurable layer Is limited during the exposing step and preferably at least one of the type, power and incident angle of illumination of the at least one source of actinic radiation is altered during the exposure step. The resulting relief image comprises a plurality of dots and a dot shape of the plurality of dots is produced that is highly resistant to print fluting for printing on corrugated board.

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 tailoring the shape of a plurality of relief dots created in a photosensitive printing blank during a digital platemaking process is provided. The photosensitive printing blank comprises a laser ablatable mask layer disposed on at least one phoiocisrahle layer which is mountab!e on a printing sleeve. The method comprises the steps of (1) placing a barrier layer on top of the laser ablatable mask layer; (2) laser ablating the laser ablatable mask layer to create an in situ negative in the laser ablatable layer; (3) exposing the at least one photocurable layer to actinic radiation through the in situ negative; (4) removing the barrier layer; and (5) developing the imaged and exposed photosensitive printing blank to reveal the relief image therein, the relief image comprising the plurality of relief dots. The presence of the barrier layer produces printing dots having desired geometric characteristics.
