Abstract
A device includes a setting section that sets a single-color amount limit and an ink total amount limit, an upper half outline constructing section, a lower half outline constructing section, a restricting outline constructing section, and a color space converter. The upper half outline points are points at which one or more color components are 0% and that satisfy the single-color amount limit and the ink total amount limit. The lower half outline points are points at which one or more color components satisfy the single-color amount limit and that satisfy the ink total amount limit. The restricting outline points satisfy the single-color amount limit and the ink total amount limit, and are connected to the upper or lower half outline points which satisfy the single-color amount limit and the ink total amount limit. The color space converter converts the constructed outline points into another color space.
