ABSTRACT:
The present invention provides a method and system for watermarking a file which is in a PDL such as PostScript. The present invention can be used to either watermark a PDL file and then generate a watermarked PDL file or the present invention can be part of the Interpreter in a printer which takes a file in a PDL and which then generates watermarked raster images which are printed.The present invention includes an “interpreter” which generates raster images from the PDL file. The raster images are then watermarked using conventional watermarking techniques. Next the raster images are either printed (if the interpreter is part of a printer) or the raster images are combined into a new PDL file.
