发明名称 Method for creating surface texture on flexographic printing elements
摘要 A method of making a relief image printing element from a photosensitive printing blank is described. The photosensitive printing blank comprises a laser ablatable mask layer disposed on at least one photocurable layer and the laser ablatable mask layer is selectively laser ablated to create an in situ mask and uncover portions of the at least one photocurable layer. The method includes a) pushing the photosensitive printing blank through a nip formed by a textured roller and a backing roller, wherein the textured roller contacts the in situ mask and the uncovered portions of the at least one photocurable layer; and b) exposing the at least one photocurable layer to at least one source of actinic radiation through the in situ mask to selectively cross link and cure the portions of the at least one photocurable layer not covered by the in situ mask. A defined topographical pattern is transferred from the textured surface of the roller to the at least one photocurable layer.

主权项 1. A method of making a relief image printing element from a photosensitive printing blank, said photosensitive printing blank comprising a laser ablatable mask layer disposed on at least one photocurable layer, wherein the laser ablatable mask layer is selectively laser ablated to create an in situ mask and uncover portions of the at least one photocurable layer, the method comprising the steps of: a) transporting the photosensitive printing blank through a nip formed by a textured roller having a texture on an outer surface thereof and a backing roller, wherein the textured roller contacts the in situ mask and the uncovered portions of the at least one photocurable layer to transfer the texture from the textured roller to at least the uncovered portions of the at least one photocurable layer, and thereafter b) exposing the at least one photocurable layer to at least one source of actinic radiation through the in situ mask to selectively cross link and cure the portions of the at least one photocurable layer not covered by the in situ mask; wherein the texture comprises a defined topographical pattern.
