QTR-Quadtone RIP

How do I look at the linearization values for the K7 inks?  I can pull
down the QuadR2400-K7 Printing Model but when I open the ink
descriptor file I don't see any profiles for R2400_K7.  Is this a
proprietary thing?  I'd like to do a little linearization of my own. 
I've been printing with the 2400 K7 curves along with a profile I made
for the paper I'm using but I'm not too impressed so far.  Very smooth
but not enough snap.  Not as nice as the Epson ABW in my opinion.  A
lot more expensive too.

Thanks,
