Digital BW, The Print

Paul, I do not know of anything for the 2200 that will give you the
flexibility needed. For the 7500 you might want to try the newest
version of the Evolution RIP. I'm sure we can get them to extend the
trial period long enough to get a few CMYK profiles built. You would
need to switch back to only 3 black inks though. Let me know if you
need  CMYK profiles. In the x600 printers you would be able to set
them up with MK, PK, k, lk, LC, LM, Y which would give a decent gamut
if you use Image Specialists Ultra Pro inks (I assume the same could
be said for the MIS Pro inks). Reds and purples would be where it
would show the greatest problems, with a little bit lacking in blue
and green. I tried this early on just to see what it what look like,
and it wasn't that bad. Using full CMY gave a noticable lack in cyan
and again a slight lack in red and purple.

If you can step up to a 4000 or 4800, then you can use the Evolution
or full Colorburst RIP. The Evolution is $500 for 17 inches and under,
$1000 for 24 and under, and $1500 for larger (last time I checked
prices). 1 Year of full support, and additional years are only around
$300. All upgrades are included during the year of support.
