The problem doesn’t come from the measure instrument (eyeOne). Because when I measure black from my elder Epson photo 950 on the same photo quality paper, I get L=15 (instead of 22) on the R800.
OK, that makes sense. Good to have a point of comparison.
You can see by eye on the printing that the R800 black of is a lot lighter then on the 950.
Following your suggestion I’ve tried to print on gloss photo paper, and this time, I got black with L=3 !
wow, OK, that’s a difference.
So it seems that Epson wants to sell it’s photo paper if you know what I mean…
The problem is that I don’t print photos and I must absolutely use matte paper. Don’t you have a trick to get better colors even on matte paper?
well… The only thing that comes to mind for that printer, using the RGB-based drivers is to try choosing different media types and see if any of them put down more ink. It might screw up your linearity but you are profiling so that helps…
Or you could drive it with a RIP and see if CMYK control over the printer gives you access to more ink. If you are OS 10 you could also try setting up a GIMP-print driver and see if the CMYK control it affords gives you better density. The screening might bite though. I’m waiting for v5 which is supposed to be much better at that.
I suppose you could also try different matte papers as well. This helps illustrate one reason why Epson has two blacks for some of the other printers…
