The present disclosure describes an apparatus and method for receiving a red (R), green (G), and blue (B) color separation signal from an appropriate source such as a photo electronic scanner; acting on the RGB signal so as to convert the RGB signal to a cyan (C), magenta (M), yellow (Y), and black (K) signal in readable form for use by an appropriate four color printing device, the CMYK signal having approximately the same color ratio as the RGB signal and outputting said CMYK signal to the four color printing device such that the printed image will have approximately the same color ratio as the original RGB image.
