Abstract
A system that selectively converts color values for objects within a document based on color profiles, wherein a color profile defines a conversion for color values between a source color space and a destination color space. During operation, the system determines whether an object-level color profile exists for an object in a document. If so, the system determines whether an object-level flag for the object is set to honor the object-level color profile. If so, the system uses the object-level color profile and an output color profile to convert color values for the object in the document.
