Abstract

This invention enhances gloss uniformity of a formed image surface by selectively using colorless inks according to dot layouts of colored inks. A dot-layout unit sets colored dot layouts for respective colors of colored ink data. A colorless-dot-layout unit sets a colorless dot layout for one colorless ink with reference to a colorless dot layout table according to the colored ink data. An image is formed according to the colored and colorless dot layouts. In the colorless dot layout table, when a specular glossiness calculated according to the colored dot layouts is high, the colorless dot layout is set to superpose a colorless ink having a low refractive index on a colored ink having a high refractive index. Conversely, when the specular glossiness is low, the colorless dot layout is set to superpose a colorless ink having a high refractive index on a colored ink having a low refractive index.
