Hi Tom,

The UT2 inkset is really two sets of inks.  There's black (which is a bit warm),
2 warm grays and 2 cool grays.  Then Y is usually a sepia ink but sometimes its
replaced with light gray (probably warmish).   So for the profiles the grays
are usually K, M, LM and possibly Y.  Then use the toner section to do a set
of cool grays that you mix in.   When you get down to it there are a lot of
combinations of how you can use the inks.   I highly recommend starting with
the existing profiles.  See how the profiles are structured and how the generated 
curves look.   In fact if you just want different papers you can probably just
re-linearize existing ones rather than starting from scratch.
