Here is the linearization off the spreadsheet for Hahnemuhle Photo Rag White 305gm paper I made with the K7 Selenium. The 21 gray step-wedge looks good too in Gamma Gray 2.2.
The QTR Curve Graph shows the dark Cyan to almost max out, with the Matte Black barely shown there. Is this normal, or should I alter the Matte Black (up) and pull back down on the Cyan? I don't know where the cool selenium color comes in at, the Matte Black or the Cyan shade? I will assume Matte Black for this paper too, although I don't see a big difference between the PK & MK ink?
Also, in the conversion from RGB into Gamma Gray 2.2 in CS6, there is also something it sometimes asks about some "Working Gray - Dot Gain 20%" or something? Local commercial lab uses that "Dot Gain 20%" in their black & whites off their 9900 through PS when I asked them. Where do you put the "Perceptual, Relative, etc." (4 settings possible) settings too in the conversion? Leave "Black Point Compensation" checked or not?
Fwiw, I have to uninstall "Adobe Flash" to upload images here for some reason. Otherwise I get red exclamation mark in the pop-up uploader for any images loaded. Might help anyone else having this issue.
