QTR-Quadtone RIP

Hi there,

   I'm new around (and to printing B&W) but after trying to have some
B&W prints on a Epson R270 I gave up. The metamerism was awaful and no
matter how I was adjusting the color balance there still was a color
cast. Now, after reading the articles of Clayton Jones about B&W
printing I wanted to try Black Only (BO) printing, but I think on an
Epson R270 there isn't the option "Black only" (there is the
"grayscale" option but I think it is not the same). Clayton Jones
mentioned that if the "Black only" option is absent I still can use a
RIP software to have a BO print.
    So my questions is:
    Can I use QTR with Epson R270 (for BO I guess I'll have to make a
custom curve using only the black ink). I saw in the supported printer
list the Epson R220 but I'm not sure about compatibility between R270
and R220.
   
   Thanks

I did, with very very good results for glossy and semyglossy Epson papers:

The curves:

I tried ont he heavyweight paper, but results are not too much
interesting, black ink is going to an awful green cast under some
types of light.

There are the curves for R380 by Carl, see in the newsgroup files.
