Abstract
Density range division of component dyes of a color hard copy which is obtained by the combination of quantized color image signals is performed so that the lightness of the gray scale of the color hard copy is equally divided in accordance with the level number of the quantized color image signals. The density range division is also characterized in that the lightness of the component dyes of the color hard copy is equally divided in accordance with the level number of the quantized color image signals.
