摘要

It is intended to allow by a simpler process, to print the background pattern more effectively, and pattern information, and the resolution of the resolution below the predetermined off to specify a pattern disappear undetectable at resolutions of resolution than the predetermined But by combining the hidden text information specifying the remaining pattern information specifying a detectable remaining pattern, the area to be printed respectively by the rest of the pattern and pattern disappear depending hidden text, the background pattern image including hidden and combining the original image data representing an original image of the object to be printed as a background pattern image including a first processing for generating the background pattern image information representing the hidden text represented by fingerprint image information and the copy-forgery-inhibited pattern image data, and a second process for generating a background pattern image insertion original image information representing an original image obtained by inserting pattern image including hidden in the background, by outputting to the printer a background pattern image insertion original image data, the hidden text I want to output the original image that was inserted into the background pattern image, including.
