<P>PROBLEM TO BE SOLVED: To provide a specific image configuration in which an image observable under normal visible light is changed to a completely different image when the image is observed under a specific condition and a latent image printed matter which can be formed by the specific image configuration, in the field of precious printed matters such as bank notes, passports, securities, identification, cards and traffic tickets which are security printed matters requiring forgery preventing effects. <P>SOLUTION: In the latent image printed matter, images are formed by complicatedly combining image elements having different area ratios. The respective image elements are observed to have the same color under diffusely-reflected light and observed not to have the same color under a specific condition. Thus, the latent image printed matter has a so-called change effect, in which a first image is visually recognized under diffusely-reflected light and the visually-recognized image is changed to a second image which is a different image having no correlation with the first image when observed under a specific condition different from diffusely-reflected light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
