That was why Epson introduced 6 color printing with the 5000: to offer smoother proofing than the 3000. Of course the output of Offset presses are less smooth than either due to the halftone dots... The fixed-proofer goal of exactly matching the gamut of the output device in the proofing device is brittle and problematic. Attaining good dithering and accurate color matching from a larger gamut system has numerous advantages, low cost being high on the list. C.
