Digital BW, The Print

I am not aware of any ink set that can provide low metamerism inks via the OEM driver, which mixes all light grays from full saturation colors, but it might be possible, if those full colors are replaced with low saturation replacements. I was under the impression that Joe Holmes Small Gamut Ink patent eliminated that possibility for other inksets. But perhaps if they don't offer a full range of tonality, it could be possible.   Similarly, I am not aware of a driver that could do that with OEM inks, without suffering the same graininess that the later 2000 OEM driver suffered, due to blending light grays from black dots. In the case if the 2200, the dots would have been less obvious from the dark gray ink that was available. But until the 2400 provided a second gray the problem would remain.
