What is RGB Color mode vs. CMYK Color mode, and which is better for color printing?
RGB (red-green-blue) are the colors of light. CMYK (cyan-magenta-yellow-black) are the colors of paints and inks. Adobe RGB (1998) is the recommended profile for Academic Technology Labs. RGB Color converts automatically at each printer for quality color. CS3 design applications in the labs default to RGB Mode, Adobe RGB (1998) regardless of whether or not they are vector or raster based.
