Abstract
A method of identifying color mismatches for objects having different rendering intents within a print job prior to printing, includes identifying all objects within the print job, each object's type, rendering intent and all source colors associated with it; for each object in the print job, transforming each object's source colors using a prototypical color transformation; identifying sets of transformed objects having source colors that match within a first tolerance; transforming all transformed objects using a target printer's color space; identifying any of the transformed objects in each set that do not match within a second tolerance level; identifying any object types within the group of mismatched objects having at least two different rendering intents; selecting one of the rendering intents in accordance with a predetermined criterion; and assigning the selected rendering intent to at least one other instance of that object type.
