<P>PROBLEM TO BE SOLVED: To obtain a favorable contrast range of a printed image and to reduce a manufacturing time by improving a method for forming a structure of photopolymerization image points on a photosensitive layer of a printing plate, particularly, a flexographic printing plate, as an image of image data comprising an image point matrix using structured exposure light from a light source. <P>SOLUTION: Each photopolymerization image point 9 is generated by individual exposure sequences 6, 8, 11 selected, in one way, according to the area density of the photopolymerization image point 9 set at positions (A, B, C, D) of the photopolymerization image point 9, and in the other way, according to image data. <P>COPYRIGHT: (C)2007,JPO&INPIT |
