Abstract

Copier color mapping is the color modeling and mapping from the scanner RGB color space to the printer device color space. It may be aimed for exact/closest color matching or for preference color matching from the source hardcopy to the reproduced hardcopy. It is not simply the linking of a scanner color characterization and a printer color characterization. Unlike other cross-color reproduction systems in which both the source color space and the destination color space are well-defined, copy source types are not controllable in general; thus, the source color space (e.g. the black and white points, color gamut, and the scanner response to the source) cannot be well-defined. Thus no exact color characterization can be made for general copy. A trade-off for the balance of overall copy reproduction or a fuzzy characterization is important for the color characterization. In this paper, we present a method for scanner characterization preserving the neutral balance, a method to characterize scanners with controllable extrapolation, selecting a gamut mapping method for optimized system color reproduction, and overall characterization methods for different source types and different print modes for the trade-off for overall copy color reproduction is achieved.
