Abstract:
1. A method for making a relief printing plate from an imageable lithographic printing plate precursor, the method comprising the steps of: imaging the lithographic printing plate precursor to produce a lithographic printing plate having ink-receptive image areas and ink-repellent non-image areas, the ink-repellent non-image areas having both hydrophobic and oleophobic character, the ink-receptive image areas and ink-repellent non-image areas defining an image; applying a first curable composition to the lithographic printing plate, wherein the first curable composition wets ink-receptive image areas and does not wet ink-repellent non-image areas, to form a substantially uniform coating of the first curable composition on ink-receptive image areas; and curing the coating of the first curable composition to produce ink-receptive cured areas including a first cured layer, such that the ink-receptive cured areas and ink-repellent non-image areas define the image.
