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.

Abstract: A method of controlling surface roughness of a flexographic printing element during thermal processing is provided. The relief image printing element of the invention comprises a photopolymer that has been selectively imagewise exposed to actinic radiation to selectively crosslink and cure portions of the photopolymer. The method generally comprises removing uncrosslinked and uncured portions of the photopolymer by heating the photopolymer and contacting it with a blotting material. The photopolymer is then contacted under heat and pressure with a smooth material, e.g., a laminated polymeric film, which smooth material is removed resulting in a relief image printing element with reduced surface roughness.

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.

The method can also be used with an analog platemaking process that uses a negative instead of an ablatable mask layer.
