PROBLEM TO BE SOLVED: To provide a print printed with a forgery preventive image which has a background and a latent image and can suppress visual recognition of the latent image as well as possible.SOLUTION: A print is printed with a forgery preventive image 2 which includes a background 5 composed of uniform-pitch dots or parallel lines, latent images 6 and 7 composed of dots or parallel lines with the phase or angle deviated from the background 5 and a camouflage image 8 which forms image regions 18, 19a and 19b different in density from the region 15 where the background 5 is formed and is composed of dots and parallel lines. Since the camouflage image 8 is conspicuous and attracts the attention of observers well, visual recognition of the latent images 6 and 7 is made difficult, leading to the most possible suppression of visual recognition of the latent images 6 and 7 and improvement of effects of authenticity discrimination and forgery prevention. |
