PROBLEM TO BE SOLVED: To maintain high color reproducibility of ink over a long period of time when the ink of a special color (e.g. red) with excellent color development properties is used in addition to inks of three primary colors of subtractive color mixture. SOLUTION: At least either (e.g. yellow ink) of the inks of two, between which a red hue angle is sandwiched, of the three primary colors is imparted in a superposed state to an area wherein the red ink is imparted onto a recording medium. Thus, since the yellow ink with good weatherability is also imparted in a superposed state to an area on the recording medium, where only the red ink with lower weatherability is to be originally imparted, the weatherability can be enhanced while the color development properties are maintained in a high level.
