Paper Abstract

Gamut mapping algorithms were tested in a transparency-to- newsprint workflow, using features derived from studies of empirical mappings in high-quality color reproductions. The experiment compared different methods of determining the achromatic convergence point in simulations lightness-chroma compression, and compared linear compression against a non- linear distance-weighted compression. Algorithms whose convergence points were dependent on the lightness and chroma of the cusp and of the color being mapping performed better than those with fixed convergence points. The models using non-linear compression were strongly preferred over one using linear compression.
