I'm surprised that you got lower contrast but wouldn't have been surprised 
if you saw no difference. The measured dMax difference someone else 
mentioned of 1.67 with Eboni vs 1.58 with Epson MK is a difference of only 
.09 log units, which is less than a third of a stop.

FWIW when I switched from Epson MK to Eboni I didn't notice any difference 
in dMax - both seemed perfectly adequate  to me using EEM and PFA- and so 
obviously I didn't see a need for different curves when using Eboni. 
However, I didn't make any measurements or make a side-by-side comparison. 
The principal difference that I saw, and the reason for the switch, was that 
Eboni has a somewhat cooler look.

Subject: [Digital BW] Re: Ultratone vs. Epson K3 Inks


Earlier this morning I ran a Eboni cart on my 2200 using QTR with the
profiles for UC MK and the Eboni print looked lighter and less
contrasty than the same print made with MK. So I'm wondering what
kind of adjustments need to be made to the profiles to take advantage
of the greater dmax that Eboni offers -- are we talking completely
new profiles? Also, would the difference be noticeable enough to make
it worthwhile. Another thought, if Eboni has a significantly better
dmax than the new black for Piezo K7 inkset, then why couldn't one
just substitute Eboni for that black?
