If you have a 1900 you can use to test one dilution of the "Eboni" you purchases, that might be enough to see a difference. The 1900 should print much like the 1400, for which I have data.

If I make the print on a R1900, with 5 shades of gray, it's ok? To fill the cartridge on the 3800 would use a lot of ink.
I usually use another diluent, my last tests with c6b didn't work well. But I will retry, I still have some c6b.
