Digital BW, The Print

Paul,

I am trying to follow your workflow for printing with the UT7 inks on
the 2200, at:

http://www.inksupply.com/ut7_2200.cfm

Unfortunately, the two links at step "D" (Making the Print) are broken.

Thanks, John

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.
