Abstract
Digital machine readable full color specifications of full color source images are embedded in the printed hardcopy versions of those images; typically through the use of a self-clocking glyph code to minimize the visual impact of the embedded data. This color specification then can be recovered from a hardcopy version of the original source image, even if the hardcopy is monochromatic. Thus, a digital highlight color copier can use this color specification to index into a plurality of different full-color to highlight-color transformse to select the transform or transorms that are most appropriate for rendering a highlight color copy of the source image.
