    摘要: The present invention provides a color image processing system for processing drawings at high speed while reproducing color tone with fidelity. The color image processing system includes a digital processor that performs a raster operation on multigradation image data and generates an output image represented by a first plurality of color components. The system also includes a processor which separates the output image data into a second plurality of color components and stores the separated data in a memory. The system includes a reverse color separator which transforms the stored image data back into image data represented by the first plurality of color components and supplies this transformed image data to the digital processor. In a preferred embodiment, the digital processor performs an under color removal/black generation conversion to separate the output image data resulting from the raster operation into cyan, magenta, yellow and black color components. The reverse color separator performs a reverse under color removal/black generation conversion to restore the stored image data to a cyan, magenta, yellow format suitable for use by the digital processor.
