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.
