Abstract
Official abstract text for this publication.
A generation unit is configured to generate a black color material data and the plurality of pieces of chromatic color material data, for a color positioned at a surface of a dark portion in a color gamut that can be reproduced using a black color material and the plurality of chromatic color materials, in such a way as to arrange dots of the black color material and respective dots of the plurality of chromatic color materials exclusively on a recording medium and set a rate of the arranged dots of the black color material to be greater as the color positioned at the surface is closer to black.
