Welcome to the group, Steve.

There is also a forum devoted just to QTR that might help.  See

Could be.

I'm not sure what the 7600/9600 usually get.  I'm using a 35 limit on a desktop unit that I was profiling yesterday.  A low ink limit is not necessarily bad.

It may have no effect on it.  With the printer I was working with yesterday the dmax was very good at a black limit of 35.  I'd guess that is about the same as gamut for color. 

Good luck with QTR.  It's a very handy tool.
