<p><P>PROBLEM TO BE SOLVED: To deal with a truth discriminable printed matter formed by parallel line pattern printing lines, in which pictures with latent images are embedded. <P>SOLUTION: In this truth discriminable printed matter, a pattern is formed on a base material by means of parallel line pattern printing lines. The pattern is classified in a region, in which patterns with latent images are not employed, and a region, in which patterns with latent images are employed. The region, in which the patterns with latent images are not employed, consists of solid lines. In the pattern with a latent image, in the width of the parallel line pattern printing line, the printing line with the predetermined width is composed of printing lines, in which the pattern with a latent image is formed under the condition that the printing line, in which the pattern with the latent image is formed, is arranged being shifted from the solid line in the region, in which no latent image is applied. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
