Gamut mapping using an analytical color gamut representation

In this study, gamut mapping between real print processes was investigated. The processes were supposed to have equal lightness ranges, hence no lightness mapping applied. Several chroma mapping methods modifying and not modifying lightness were systematically evaluated. Pure clipping of chroma resulted as the best technique when lightness was left untouched. However, a few images required adjustments of lightness in order to retain higher chroma. These investigations were used to gain practical experience with a new, analytical color gamut representation recently published. The new representation method displayed no kind of anomalies and hence proved to be fully practical.
