Abstract: A method of producing a relief image printing element from a photocurable printing blank. The method includes the steps of a) providing a photocurable printing blank, the photocurable printing blank comprising (i) a backing or support layer; and (ii) one or more photocurable layers disposed on the backing or support layer. The one or more photocurable layers comprise a photocurable composition comprising (1) a binder; (2) one or more monomers; (3) a photoinitiator; and (4) an additive. The one or more photocurable layers are selectively imaged by exposing the layers to actinic radiation to selectively crosslink and cure portions of the one or more photocurable layers, and then developed to remove uncured portions of the one or more photocurable layers and reveal the relief image therein. The relief image comprises a plurality of relief printing dots, including relief printing dots that have a rounded top and relief printing dots that have a flat top.

Abstract: A method of controlling surface roughness of a flexographic printing element during thermal processing is provided. An imaged and exposed relief image printing element is thermally developed to remove the portions of at least one layer of photopoiymer that are not crosslinked and cured by a) heating the at least one layer of photopoiymer to a sufficient temperature to soften uncured portions of the at least one layer of photopoiymer; b) causing contact between the at least one layer of photopoiymer and a blotting material, wherein when the blotting material contacts the at least one layer of photopoiymer, the softened uncured photopoiymer portions of the at least one layer of photopoiymer are absorbed into the blotting material; and c) separating the blotting material from the at least one layer of photopoiymer. Thereafter, a smooth material is inserted between the surface of the at least one layer of photopoiymer and the blotting material, in the alternative, after the flexographic printing element is removed from the thermal processor, a polymeric film is laminated onto the relief image printing element using heat and pressure. Based thereon, the average surface roughness of the relief surface of the- flexographic printing element can be reduced.

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.
