Digital BW, The Print

Hi,

After starting out with UT2 inks in a 1280, I recently purchased a
2200.  I really like the way QTR looks on matte papers, but on
"glossy" (prem. glossy, semigloss, and luster) papers, there is always
a brownish tint.  Though the UT2 prints I made on semigloss had major
bronzing, they were much more "neutral" (i.e., black and gray).

Using the sliders in QTR hasn't really helped much, as even with the
cool settings it seems that the print really isn't neutral.

So - my questions are these:

 - is there some way to get non-brownish prints on RC papers with QTR
and the 2200 (UC inks?

 - if I want to try the UT7 inks in the 2200, do I need to buy all 7,
or is there a way to get a minimal set (like PK, LK, and ???) just to
try it out before I buy the refillable cartridges and ink?

Thanks in advance,
Eric
