Abstract

Computer systems can be used to interconnect many different types of color devices: monitors, printers, film and video recorders. Techniques based on CIE standards provide a degree of “device independence” to color reproduction in these systems. However, reproducing tristimulus values, pixel by pixel, will not result in acceptable color reproduction for images or related color sets. Differences in gamut and appearance characteristics make an additional transformation step essential, a step we call gamut mapping. While this model has proven useful for color reproduction across media [11], there are still research problems left to be solved before it can be fully realized. This paper will discuss these issues and also some of the inherent limitations of this approach to color reproduction.
