<p><P>PROBLEM TO BE SOLVED: To provide an intaglio printing plate for a machine plate, in which patterns having dimensions and shapes different from one another are formed by a reversing printing method so as to manufacture a liquid crystal color filter with a high nominal grade. <P>SOLUTION: The intaglio printing plate 100 for a machine plate with plate depth different from one another in every pattern is formed by repeating the formation of a photosensitive layer on a machine plate-based base material 11, a pattern-wise exposure and a development treatment by a plurality of times. Concretely, the first photosensitive layer 21 is formed on a machine plate-based base material 11. The first photosensitive layer 21 is pattern-wise exposed and developingly treated in order to form a first intaglio printing plate 20 having an opening part 22 for an alignment mark and an opening part 23 for a frame pattern formed thereon. Next, the second photosensitive layer 31 is formed on the first intaglio printing plate 20. The second photosensitive layer 31 is pattern-wise exposed and developingly treated in order to form a second intaglio printing plate 30 having an opening part 32 for the alignment mark, an opening part 33 for the frame pattern and an opening part 34 for a pixel pattern on the first intaglio printing plate 20, resulting in producing the intaglio printing plate 100 for the machine plate with plate depth different from one another in every pattern. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
