摘要： An image processing apparatus prints an image using a plurality of color materials and a colorless material. A memory stores information indicating a plurality of dot placements which include different dot placements of the colorless material, and correspond to an amount of the colorless material. Color material amount data indicating amounts of the plurality of color materials and the amount of the colorless material is input for each pixel. A dot placement of the colorless material is determined from the plurality of dot placements based on the amount of the colorless material indicated by the input color material amount data, so that coloring of specular reflection light on each pixel becomes closer to an achromatic color.

摘要： An image processing apparatus for printing an image using a plurality of color materials and a colorless material includes a memory which stores information indicating a plurality of dot placements which include different dot placements of the colorless material and correspond to an amount of the colorless material, and an inputting unit configured to input color material amount data indicating amounts of the plurality of color materials and the amount of the colorless material for each pixel. In addition, a first determiner is configured to determine a dot placement of the colorless material from the plurality of dot placements based on the amount of the colorless material indicated by the input color material amount data, so that coloring of specular reflection light on the pixel becomes closer to an achromatic color. A printing unit is configured to print the colorless material on the color materials subsequent to the color materials having been printed, based on the determined dot placement.

摘要： 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.
摘要翻译：本发明通过根据彩色油墨的点布局选择性地使用无色油墨来增强形成的图像表面的光泽均匀性。点布局单元为彩色墨水数据的各种颜色设置彩色点布局。根据彩色墨水数据，无色点布局单元根据无色点布局表为无色墨水设置无色点布局。根据有色和无色点布局形成图像。在无色点布局表中，当根据着色点布局计算出的镜面光泽度高时，无色点布局被设置为将具有低折射率的无色墨叠加在具有高折射率的着色墨上。相反，当镜面光泽度低时，无色点布局被设置为将具有高折射率的无色墨叠加在具有低折射率的着色墨上。
