ABSTRACT:
Colors look differently when observed under sunlight and room light. At least three chromatic colors and additional chromatic colors differing in hue from said three colors are used in combination. The additional colors are those which have a spectral reflectance which smoothens waviness in the spectral reflectance curve of the nearly achromatic color produced by the combination of the three chromatic colors. As the result, the combination of the colors gives rise to a color which has almost uniform spectral reflectance over the entire region of wavelengths. Thus it is possible to obtain printing which is less vulnerable to change in color under different light sources.
