PRINTING PLATE FOR REVERSED RELIEF OFFSET PRINTING, METHOD OF FABRICATING THE SAME, AND METHODS OF FABRICATING SUBSTRATE AND DISPLAY DEVICE
Abstract:
A printing plate for reversed relief offset printing ensures the prevention of the internal omission of a desired pattern without increasing the depths of depressions of the plate. The printing plate comprises a base material having depressions and a non-depressed part on a surface thereof, and ink repellent layers that cover inner surfaces of the depressions, respectively. The depressions of the base material whose inner surfaces are respectively covered with the ink repellent layers have a plan shape that defines a desired pattern. The non-depressed part of the base material is formed in such a way that a part of an ink film corresponding to the non-depressed part can be transferred to the printing plate in a process of reversed relief offset printing. The parts of the ink film corresponding to the depressions are not transferred to the printing plate due to the repelling action of the ink repellent layers.
