I believe Tom Moore wrote a tutorial for the QTRGui for Windows users.

So, if you're using different ink limits for different inks, say a limit of 60 for K and a limit 
of 80 for LC, how would you calculate the adjusted Gray Value?

Also, another question:  in the UT7 inkset, I find that LK is not being used in the QTR 
profiles.  Does that affect the Overlap percentage (which seems to be 16% in the profiles 
I've looked at)?  In other words, if you are using a gray lighter than LK for overlapping with 
K, might overlapping it decrease your DMax, rather than increasing it?
