ABSTRACT:
A condition determination unit (102) determines a to-be-used copy-forgery-inhibited-pattern image from a first copy-forgery-inhibited-pattern image generated using a latent pattern designed as a pattern that becomes visible upon copy and a background pattern designed as a pattern that becomes invisible upon copy and a second copy-forgery-inhibited-pattern image generated using the latent pattern. A tint block image generation unit (105) generates the determined copy-forgery-inhibited-pattern image. A combining unit (106) combines the generated copy-forgery-inhibited-pattern image with a print target image. A print data processing unit (107) generates print data on the basis of the combined data and outputs the print data to a printer (108).
