<p><P>PROBLEM TO BE SOLVED: To provide an image forming body having a latent image which is hard to duplicate or forge and has a freedom of design, in regard to the image forming body utilizing a forgery preventing technique for providing a line-pattern-shaped embossed projection part on securities or the like. <P>SOLUTION: One image forming body is constituted of a background part 7 which is formed of the line-pattern-shaped embossed projection part on a base 30 and printed halftone dots 12 of one color provided at the same pitch as the projection part, in parallel thereto, and shifted therefrom by about a 1/4 pitch, and of a latent image part 5 which is so formed in the projection part as to be shifted therefrom by about a 1/2 pitch. The other image forming body of which the image is different in a shape from the latent image part 5 constituting the above image forming body intersects this perpendicularly. In the image forming body 1 having the latent image thus constituted, the latent image part 5 "T" appears to be in the color of the halftone dots or white when viewed from above obliquely laterally, while the latent image part 5 "P" appears white or to be in the color of the dots when viewed from above obliquely longitudinally. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
