1. A computer-implemented method of identifying color mismatches for objects having different rendering intents within a print job prior to printing, comprising: identifying all objects within the print job, each object's type, each object's rendering intent and all source colors associated with each object; 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 level after the prototypical transformation process; 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 to form a group of mismatched objects; and displaying the group of mismatched objects in a user interface, wherein the display includes each object in the second set, all source colors and rendering intents associated with each object and information indicating which objects will not match when printed on the target printer.
