Enhancing the SGCK Colour Gamut Mapping Algorithm
  DOI :  10.2352/CGIV.2004.2.1.art00104  Published OnlineJanuary 2004

The SGCK gamut mapping algorithm suggested by CIE TC8-03 has been enhanced by introducing a two-step procedure. Firstly, SGCK is used for gamut mapping the image onto a convex hull representation of the reproduction gamut. The resulting image is then further mapped onto a more realistic representation of the reproduction gamut using hue-angle preserving minimum ΔE*ab clipping. Panel testing with fifteen test persons, six different test images, and two different printers shows that this technique gives significantly better results than SGCK.
