The ability of gamut mapping algorithms to handle a wide range of relative gamut volumes was evaluated. Five gamut mapping algorithms were tested on reproduction media ranging from glossy, coated paper to newsprint. Original media were photographic transparency and print, and CRT. The psychophysical results indicate that the performance of gamut mapping algorithms is not greatly dependent on gamut volume of either original or reproduction media. Those algorithms which apply a linear scaling of lightness between original and reproduction are more consistent in their performance across different image types and reproduction media. The methods which performed best tend to be those that give more emphasis to preserving lightness over chroma.
