Digital BW, The Print

hello,
  I'm owner of an R1800 (same driver etc  as R800) and with specific's curves made wirg QTR I finally succed by having quite good (at least for me ;-)  ) BW prints WITHOUT any other colors
   
  I Check it under big magnification with binocular on the neutral curves I did . of course with the warm curves or sepia I added very few yellow or red...
   
  the R1800 /R800 have B&W abilities only with QTR , I never succed before using this RIP to get real B&W prints - it was allaways some "greenish" or other colors on certain grays (green closed to 40% and magenta around 70% gray scale) 
   
  Check on the files and try the curves !!!
  BTW please give me your comments, 
  bye from France

          From my experience printing, or rather, attempting to print BW with 
an R800, I believe the red and blue inks are used. At least that is 
what I suspicion happens. I never made any color prints on the 
printer and the red and blue carts ran out of ink just as fast as 
the others. I don't think it was just cleaning cycles that used all 
the red and blue because I always had my printer powered on except 
when I was traveling.

FWIW, I never got a single decent BW print from the printer so I 
sold it to someone that prints only color. He loves it.
