Abstract
A method for object based color matching when printing color documents. Objects are anything that can be drawn, and include text, rectangle, oval, region, polygon, and PixMaps. Color matching is performed on each object in a page prior to rendering the object into a pixel map. This is accomplished by setting up multiple concurrent color matching sessions that have different rendering intents. Depending upon the object type, a color matching session with a particular rendering intent is used to perform color matching on the object.
