ABSTRACT:
A color image recording apparatus such as a color printer records a color image based on color image data supplied from an external source such as a host computer. The color image recording apparatus includes a memory for storing an image color change pattern as a function of a recording position, a central processing unit for calculating an image color at a recording position according to the function, and a color image recorder for recording a color image on a recording medium in the calculated image color at the recording position. The memory may store a color change pattern on a background free of color image data, and the central processing unit may calculate a background color based on the color change pattern on the background which is stored in the memory.
