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.

Just received some pints of Eboni v1.1 ( K ). My first tests give a very low Dmax compared to the old Eboni.
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.
