In my case, there was no Epson paper selection that provided an acceptable
media setting check. I simply guessed that VFA had the highest the ink load
and it was similar in weight to PFA so I started with it.

I then printed several media setting check images with various Color density
settings until I had bracketed the range where mottling stopped (around -20%
to -25%). I then tried printing (with Color Management turned off) a series
of 100% black squares at different color densities to see how the dmax was
affected. I found that -25% had a close enough dmax (1.60) that I chose it.

I find now that, printing with the profile I created, I can only achieve
1.57 dmax, but looking at the media setting check images again, I think I
might be able to raise the ink limit to -20% and get better dmax. I can get
1.65 dmax on PFA with QuadtoneRIP with UT7 inks which I think uses the same
matte black (Eboni).
