Abstract
Abstract Method and apparatus for printing a color document file having page description commands including process color commands for graphic objects and bitmapped images on an accent color printer. A particular accent color and shade is assigned to each primary color and a particular accent color is assigned to all bitmapped images. A print driver responsive to the color document file and particular color assignments adds color mapping parameters to the color document file to produce a modified color document file. A raster image processor connected to the print driver and responsive to the modified color document file maps the process color commands in the color document file to a shade of a particular accent color for each graphic object, maps the process color commands for all bitmapped images to a specified accent color, and produces a plurality of full page bitmaps, one for each accent color. A print engine capable of printing a plurality of accent color s, is connected to the raster image processor for receiving the full page bitmaps and prints the accent color document. The color document file is supplied to the print driver and raster image processor for printing the accent color document.
