Abstract
A printer device and a picture printing method is disclosed, in which, if the gradation for cyan is to be represented, an ink C′ of low concentration is superimposed to represent the low gradation area. This cyan ink is used in combination with a high-concentration blue ink B and a high-concentration green ink G to represent a high gradation area. In representing the high gradation area, the emitting proportions of the high-concentration blue ink B and the high-concentration green ink G are changed to enable the color hue in the high gradation area to be varied delicately to improve color reproducibility.
