Digital BW, The Print

I too am getting excellent B&W results with the Epson RIP for the 2200. I have made many tests with photographs and the grey scale. 

The grey scale shows very distinct separation from 0% to 100%. Also there is good separation from 0% to 5% but none from 95% to 100%. I see no lines, dots or metamerism either under bright sunlight (it is bright virturally every day here in Southwest Florida) or under incandescant lighting. I used a magnifying glass for the viewing even though I never think of looking at a photograph of mine with a lupe or a magnifying glass. My observations were corroborated by two friends, one of whom has had many years of printing B&W's in a wet darkroom and the other has been printing B&W using an Epson 3000 with Cone inks.

The lines (lp/mm) of 1.8, 2.4 and 3.6 are distinct, clear and sharp. But, this is not true at 7.2 lp/mm.

I have settle on the color settings, density of 108% and with no profile. My guess is that with a proper profile chosen that the results could get better. I am using matte black ink, Epson's Enhanced Matte paper, Win XP and have made prints using both Qimage and PS7. Qimage may produce a touch better print but of that I am not sure yet.

I have not messed with color printing with the RIP since the regular 2200 driver does such a nice job.

  get an acceptable toned print yet (see below).

  Tricked the RIP into printing Matte Black UC at 2880x1440 dpi on EEM 
  and got unsatisfactory results (grayscale gradient not linear). Need 
  to figure out why.

  Tried printing a duotone image in an attempt to get a toned print and 
  preliminary results were unacceptable. It might be how I'm inputting 
  my profile into the RIP, but who knows since the documentation is so 
  lacking. Epson needs to put a decent manual on their site for 
  download -- sure would save a lot of trial and error time (and money).

  I have a feeling metamerism will rear its ugly head when printing a 
  toned image since metamerism is a function of the ink. The IP5 
  tintpicker avoids this, evidently, by not using certain inks -- I 
  don't think the ERIP does that, but we'll see.
