<P>PROBLEM TO BE SOLVED: To provide a watermark generation program allowing a computer to generate a watermark to be printed by an image forming apparatus more appropriately than ever before. <P>SOLUTION: A printer driver 22d causes a Macintosh (R) 20 to execute a pre-process step of synthesizing a watermark with a document on the file thereof before Postscript data is generated and a post-process step of adding the image data of the watermark to the Postscript data after the Postscript data is generated, where the post-process step adds the image data of the watermark to the Postscript data only if the watermark has not been synthesized with the document by the pre-process step. <P>COPYRIGHT: (C)2013,JPO&INPIT |
