Considering the one - sidedness and inaccuracy of knowledge discovery only from single - color database , an approach is proposed to discover knowledge from 1331 groups of mix - color database with partial least - square regression , based on measuring and learning 400 groups of single - color database . by this method , the mean error decreases when converting from rgb to cmyk , the precision of color matching is improved , and the automatic and general problem in color matching is further solved
