<P>PROBLEM TO BE SOLVED: To provide a print having a visible image and a latent image in which a latent image different from a visible image appears when the print is copied by a color copier. <P>SOLUTION: In the print, a plurality of first half-tone areas and second half-tone areas are arranged on a base material to form visible images and latent images thereon. The print is formed of color materials which are changed from the first color to the second color when copying any one of first and second dot parts in each first half-tone area and second dot parts in the second half-tone area by a color copier. The other area in which the above-described material is not formed in the first half-tone area is formed of a color material of the first color. In the print, the visible images observed under the normal light and the latent images appearing on the print appear as images completely different from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
