Abstract [en]

The underline idea of grey component replacement (GCR) is to replace a mixture of primary colors (cyan, magenta, and yellow) by a black. Current algorithms of GCR are mainly based on the concept of equal-tone-value-reduction or mixing equal amount (tone value) of primary colors generating gray, which in turn can be represented by the same amount of black. As the colors used are usually non-ideal, such a replacement can result in remarkable color deviation.    

We proposed an algorithm of maximal GCR based on color matching, i.e. the black is introduced in a way that preserves the color (before and after GCR). In the algorithm, the primary with smallest tonal value is set to be zero (tone value) while the other two are reduced according to the color matching calculations. To achieve a real color matching of print, dot gain effects have been considered in the calculation. The proposed algorithm has been tested successfully for FM halftoning using an electrophotographic printer.
