Abstract

Existing device independent color representations are based on standards established for identifying single colors viewed on a neutral background or quantifying small differences between similar colors. However, when reproducing images or illustrations, the relationship between colors is often more important than the fidelity of individual colors. Furthermore, clients often choose to adapt their output to individual device limitations to get the best reproduction for each medium. The process of maintaining the appearance of an image while mapping the colors to fit the gamut of the target device is called gamut mapping. This paper describes nonlinear adjustment of the image colors in lightness to control the dynamic range, and in chroma to bring overly saturated colors inside the target gamut. The authors perform calculations in the CIE L*a*b* color space. Benefits and limitations of this approach are described.
