Abstract
A color image processing system having an under color removal (UCR) function is provided. A mode set switch is preferably provided to set the UCR function to be operative or inoperative selectively. An UCR rate setting unit is preferably provided so as to varyingly set the UCR to be applied to color image data. Data of four color components, including cyan, magenta, yellow and black, are processed. In the preferred embodiment, the three color components other than black are processed and printed first, and, then, a black component image is printed at the end.
