Abstract
Color patches established at given intervals are calorimetrically measured to determine a relationship between color signals Y, M, C, a lightness index L*, and chromaticnesses a*, b*. The determined relationship is processed by a dual regression analysis to determine color signals to be interpolated with priority in the order in which changes in the indexes are progressively greater as a color signal changes. The color signals are then interpolated with priority in the above order, and a highly accurate color conversion table is generated.
