Abstract:
In accordance with the present invention, a system and method are described for producing pure gray tones on a multi-color document output device that includes a system for operating on device independent color data having at least three color components, which color data corresponds to one or more associated electronic documents. The system and method function to extract grayscale data from such a device independent color data description, which grayscale corresponds to a rendering and a single color space. Such resultant data, inclusive of a color data portion and a grayscale portion, is thus completed in device independent form.
