For another data point, Eboni (original) on Canson Rag produced a dmax of 16.31 on a test I found, the same as the v. 1.1. These were both with the 1400.
What printer are you using?
I looked at a few tests of Epson Hot Press with the 1400 and found the following Lab L numbers for the 100% black: 13.83 - 13.9 (original Eboni), 14.3 (Eb. v.1.1).
My original impression of Eboni v.1.1 was that it actually produced a slightly better dmax than the original on at least some of the papers I often use. The above tests don't show that, but they do indicate that the results in terms of dmax ought to be close. The major difference I noticed was that the dilute v.1.1 produced a distinctly warmer image than the original on Epson Hot Press.

I printed some Canson rag in October using an Epson 1400. The dmax ranged from 17.33 (Epson driver) to 16.21 (QTR). These were same day measures, dried with a hair drier. I expect they got higher overnight. While batches of ink do vary, and the dmax also varies depending on how dry or "cured" it is, a dmax of 19.5 seems very low. Assuming the print was dry, I'd say there is something wrong. You might want to contact MIS.PaulOn Fri, Jan 29, 2016 at 3:26 PM, phlg@...

The tests are made on Canson Photo Rag. I have just printed the K ramp with QTR in calibration mode.
With the old Eboni, the better LAB L* value is around 15.5.
With the Eboni v1.1, the better LAB L* value is around 19.5.
The nozzles were ok, I purged the lines, made some tests on different printers, different lines and cartridges, but nothing to do.
I have also tried some dilutions with the same proportions I usually use, and the results are really lighter.
Do you think it's a bad blend ? Until now I never had this kind of problem.
