I have your Eboni-6 pdf, will study it again. The screen shot shows Win 7 and CS4, whereas I'm still in XP and a humble version of Elements ...
... I went to my QTR and pulled down the paper choices, and there was my Premier Art FineArt 205. I'd forgotten that many of your profiles are included in QTR. Got a very nice test print first try.
I see what you mean about this setup having smoother light tones, as against the R1800/3MK. This profile had "BO" in the name. Does this mean I'm printing only with the K cart and none of the other five?
I looked at a 21 step scale in a test print the next to last frame was indistinguishable from the very last frame (black). However there was clear delineation of all the steps at the lighter end, which speak for good highlight detail.
