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.
Claims10
A process for reproducing highlight color copies of full color source images from hardcopy versions of said source images that are of unknown color fidelity;
- said process comprising the steps of
- embedding a digital machine readable full color specification for at least a portion of a source image in a hardcopy version of said image;
- scanning said hardcopy version of image to produce a digital representation thereof, including said digital full color representation;
- processing said digital representation of said image to recover said full color specification;
- indexing into a plurality of different full-color to highlight-color transforms in accordance with said full color specification to select at least one of said color transforms for rendering a highlight color copy of said image;
- and
- printing said highlight color copy.
