The 3-MK workflow is not as smooth as the UTR2. In fact, it's not quite as smooth as the 1400 Black Only mode printing, but they are close. What some of us have noticed is that the noise in the process seems to be additive with noise in the image. I suppose that is normal for noise in any system, but it sometimes seems to result in an unexpected level relative to, for example, what we we see in the 21-step test strips.
I can't say for sure that the sample images you posted are "normal" for the 3-MK workflow or not. If the nozzle check was fine, then they probably are.
I find with the 1400 that I now use for most 11x14 prints is that I use a blend of profiles that combines Eboni-6 (or "Eboni-5" in the current inkset I use) with Black Only. Using a 50-50 blend of the profiles in QTR with the sliders seems to tame the roughness as well as bring the warmth of the dilute Eboni approach down to what I find pleasing. At the same time, it retains the 100% carbon aspect that I favor.
I'm told, by the way, that MIS now has carts for the 1800 that do not have the sponges in them that interacted with Eboni-6, but I have not seen these. They are apparently similar to the 1400 carts. I think I bought my latest 1800 carts from www.Inkjetcarts.us, but I don't use that printer now.
The inkset I'm now using is written up at http://www.paulroark.com/BW-Info/Eb1400.pdf It's basically Eboni-6, inclusing the Eboni BO option, with one position for HP's Z3100 neutral PK. With my 1400, one position is enough for smooth glossy and toned matte prints. On the 1800, I doubt one position would be smooth.
I have 1600 dpi scans of several printing modes on the last page of the above PDF.
