Digital BW, The Print

Hi.
Just installed UT-FSN ink on a 1160. The curves I found for this 
inkset was those from Paul for the FS. Are there any curves 
separeted fot the FSN? Printing with the FS graysscale curve,no 
color adjustment,gamma 2.2 space (I'm in a PC)and printe color 
space "same as profile" ,on EAM gives me a good 21 step ramp from 0 
to 100 %,but the small one from 95 to 100% prints solid black...
Any hints?
Thanks,
 André Vallejo
