ABSTRACT:
In a color image forming apparatus, a color document read by image inputting means is converted to RGB data and then to L*a*b* data. The L*a*b* data are subjected to image processing and then transformed to RGB data. Further, the RGB data are transformed to YMCK data. Image outputting means sequentially superposes color materials on a paper on the basis of the YMCK data, thereby reproducing the color document. Recognizing means recognizes a color rendering range for the L*a*b* data and a color reproducible range available with the outputting means. Data representative of the color rendering ranges of the inputting means and outputting means are stored in a data storage and supplied to the recognizing means.
