  • Patent number: 9469123
    Abstract: An inkjet printing apparatus and an inkjet printing method capable of suppressing generation of bronze phenomenon regardless of the color gamut are provided. For this purpose, in multipass printing, more pixels permitted to print by at least one type of achromatic color ink than pixels permitted to print by chromatic color ink in the last print scan to a unit region are set. Accordingly, it becomes possible to apply achromatic color ink having a high bronze phenomenon reduction effect on the topmost layer of the print medium, and thereby generation of bronze phenomenon can be suppressed without any hue shift.
