Patent ID: 7168868

Claim:
A 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 is set; and control means for notifying a user that the black-and-white printing mode is to be changed 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 the color copy-forgery-inhibited pattern is set, wherein 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 a black-and-white copy-forgery-inhibited pattern is set, the control means generates a black-and-white copy-forgery-inhibited pattern image based on a setting of the black-and-white copy-forgery-inhibited pattern so as to print the generated black-and-white copy-forgery-inhibited pattern image and a black-and-white converted manuscript data without notifying the user; wherein the apparatus prestores concentration parameters for generating the copy-forgery-inhibited pattern image in the case that the black-and-white copy-forgery inhibited pattern is set, and the control means replaces concentration parameters with the prestored concentration parameters for generating the copy-forgery-inhibited pattern image in the case that the black-and-white copy-forgery inhibited pattern is set and generates a black-and-white binarized copy-forgery-inhibited pattern image using the replaced concentration parameters after the notification 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.
