ABSTRACT:
If an ink for a particular color (for example, red) having an excellent color developing characteristic is used in addition to inks for three primary colors of subtractive color mixture, the high color reproducibility is to be maintained for a long period. To accomplish this, at least one (for example, a yellow ink) of the inks of two colors between which the hue angle of red, included in the three primary colors, is sandwiched is applied to an area of a printing medium to which a red ink is applied so that the inks overlap each other. Thus, the yellow ink, having a high weatherability, is applied to an area on the printing medium to which only the red ink, having a low weatherability, is otherwise applied. It is therefore possible to improve the weatherability while maintaining the color developing characteristic at a high level.
