Color gamut data creating device for image forming apparatus creating color gamut data to indicate distribution range of measurement points projected on each target plane
A color gamut data creating device includes a target plane determining unit. The measurement points are defined in a color space. The color space has an achromatic axis and an axis perpendicular to the achromatic axis. The target plane determining unit further determines a plurality of target planes. Each target plane has a fixed hue angle and including the chromatic axis. A difference between a maximum saturation at a hue angle of each target plane and a maximum saturation at a hue angle of another target plane that is adjacent to the each target plane is lower than a prescribed value. The locating unit that projects, on each target plane, those measurement points that are within a prescribed range relative to the subject target plane. The color gamut creating unit creates color gamut data indicative of a distribution range of the measurement points projected on each target plane.
