Hi James, The RGB and CMYK color spaces each contain colors that the other one cannot represent. But I do not think that is your problem. Computer monitors and printers and projectors vary wildly in the colors they produce. The easiest way to diagnose what device is contributing most to the color mismatch is to compare your Chimera image printed from two color printers, and on two or more different monitors. If the problem really is RGB versus CMYK color representations you might look at the figure in the middle of the following page: http://dx.sheridan.com/advisor/cmyk_color.html It shows the boundary in color space of the colors that can be reproduced by an RGB monitor and in CMYK printing. It suggests that the RGB monitor saturated blues and greens are outside the range of the CMYK gamut. Tom
