ABSTRACT:
The publication prolog of a PostScript page description language (PDL) or other PDL file is modified to create traps within an interpreter or raster image processor (RIP). The publication prolog is modified to provide the trapping instructions to the RIP, while the script is sent unmodified to the RIP. In a preferred embodiment, modification of the publication prolog to instruct the RIP includes creating a directory of the color objects in the publication, and trapping the color objects in the publication using the directory. Thereafter, the modified publication prolog and script are sent to the RIP and trap areas are created as the publication is rendered.
