ABSTRACT:
A four channel color display processor is described using separated cyan, magenta, yellow, and black color descriptions for color components. Each color component is then modified to enable use with a color monitor utilizing red, green, and blue phosphors. Colors are corrected prior to presentation to the color monitor, to eliminate the non-idealities of the color monitor, printing inks, or both. This invention allows the representation of colors shown in the color display to more accurately reflect the actual printed output.
