Digital BW, The Print

I've just installed new cartridges and CIS with UT inks in my Epson 
1160. A nozzle check showed magenta was not printing along with some 
gaps in the other inks position. Made 2-3 head cleaning cyles without 
success, so I waited some 24 hours.

After 24 hours, nozzle check showed magenta still not printing, so I 
just raised the two ink cartridges some 1/8 inch and re-seated them 
firmly. A nozzle check confirmed magenta was printing and two head 
cleaning cycles later everything was printing smoothly.

Afterwards, I bring in an image on the screen, do some basic 
ajustments and applied Paul's UT11-N1 curve. The image then took a 
high contrast look without any mid-tones. But much to my amazement, 
the image was printed exactly as it appeared on the screen.

I then made another print without the UT curves being applied, and 
bingo, a nice print!!!

As recommended by Paul, I used "No Color Adjustment" (in the driver 
color management box) and Adobe RGB (1998) (Edit, Color Settings).

Now how do I get the UT curves to work ?
Cheers,
Andre
