Digital BW, The Print

I downloaded QuadToneRIP yesterday and have been making wonderfully
detailed prints with it. 

For those of you who have not used it, it is a heck of a program!  It
is easy to use and will significantly improve your print quality.

However I immediately hit a significant road block and have not
figured a way out yet.  I am using the UT inkset with Epson 1160 in
Windows XP Home Edition but no matter what I select for curves, all my
prints are coming out with warm tone.

Here are my settings: 

1160 printer driver
Printing model: Quad1160
Media Type: Matte Paper
Resolution: 1440 Super, Speed: Better
Dither: Ordered
Curves UT-EEnhMatte-cool, UT-EEnhMatte-cool, Blend: 50%
Ink Limit Adjustment: -10
Gamma Adjustment: -10
(The latter 2 settings are because my image is on the dark side and I
want a lighter print.)

Course I have checked the nozzles and they are printing perfectly.

Any ideas?

Much appreciated,
