You can output color bitmaps as CMYK, RGB, or grayscale. PostScript output typically uses the CMYK (cyan, magenta, yellow, and black) color model to print bitmaps. If you are printing color bitmaps to an RGB (red, green, and blue) or CMY (cyan, magenta, and yellow) printing device, choose RGB from the Output Color Bitmaps As list box.
RGB devices receive RGB values instead of CMYK values. CMY printing devices convert RGB to CMY (three-color model to three-color model) more easily than CMYK to CMY (four-color model to three-color model.)
