摘要：
An image processing apparatus configured to generate image data for forming an image using a plurality of color materials of similar colors and of different densities includes a gradation changing unit configured to conduct a gradation changing process for changing gradation of C, M, Y, and K signals of an image and a color separation unit configured to conduct a color separation process for separating color component data for a dark color material into color component data for a dark color material and color component data for a light color material. The gradation changing unit is configured to conduct the gradation changing process before the color separation unit conducts the color separation process.
