Abstract

An image printing apparatus (100) can print an image in which graininess is suppressed while using a color material of light blue. To achieve this, the color material of light blue satisfies the following condition. L B ¥ L C L C > 0 and L B ¥ L M L B > 0 Here, L C represents a difference in lightness between cyan ink and a blank area, L M represents a difference in lightness between magenta ink and the blank area, and L B represents a difference in lightness between light blue ink and the blank area. Further, the color material of light blue satisfies the following condition. h c + h C + M h c / 2 ¤ h B ¤ h M h M h C + M / 2 Here, h C represents a hue of the cyan ink, h M represents a hue of the magenta ink, h (C+M) represents a hue of the image printed with the cyan ink and the magenta ink in the same amount, and h B represents a hue of the light blue ink.
