Digital BW, The Print

Hi Everyone -

My problem is that with every curve set I get a weird inversion in my
stepwedge around the 70% point, this causes images to have a solarized
look, as 70% grey prints _darker_ than 85%, so there's a weird light
point in what should be shadow areas. (My config - 1280, nomorecarts
CIS, MIS VM ink in 4 oz bottles, mac OSX using photoshop7 (but have
checked with os9 and PS6, same results)) 

So far I've tried all the Roark and Boley curves with minimal success,
and I'm getting really frustrated. Have spoken with Bob at MIS who
swears it isn't an ink problem (though he's investigating right now)
but I'm also pretty sure it isn't a printer or workflow problem since
I was getting great prints before using VM carts. Purge patterns look
pretty much normal, I am _certain_ that I have the ink positions
correct, certain that I am printing on the right side of the paper,
and certain that I am using the same settings that gave me good
results with MIS VM carts before switching to CIS. I'm pretty sure
that I can rule out software issues, as my system hasn't changed since
I was printing with carts.

There was a message from a guy named Kevin in response to my first
plea saying that he was having similar problems with an MIS CFS system
and the VM ink - I'm guessing that since he bought the ink around the
same time I did, and since he's using a different delivery system,
maybe it really _is_ the ink. That would sure make life easier if it
were true. Beyond that - does anyone have any thoughts of what might
be going on?
