Patent ID: 7474439

Claim:
A printing control apparatus, which generates printing image and transmits the printing data to a printing apparatus, said printing control apparatus comprising: first judging means for judging whether a black-and-white printing mode is set; second judging means for judging whether a color copy-forgery-inhibited pattern or a black-and-white copy-forgery-inhibited pattern is set; and copy-forgery-inhibited pattern image generating means for generating a binary black-and-white copy-forgery-inhibited pattern image in the case that the first judging means judges that a black-and-white printing mode is set and the second judging means judges that a color copy-forgery-inhibited pattern is set, wherein the binary black-and-white copy-forgery-inhibited pattern image is expressed in binary representation of a black density of 0% and a black density of 100%, and wherein the binary black-and-white copy-forgery-inhibited pattern image generated in the case that the first judging means judges that the black-and-white printing mode is set and the second judging means judges that the color copy-forgery-inhibited pattern is set is the same as a binary black-and-white copy-forgery-inhibited pattern image generated in the case that the second judging means judges that the black-and-white copy-forgery-inhibited pattern is set.
