Digital BW, The Print

I usually sit in the background and learn from all the good discussion
here.  As a result of this, I've just started experimenting with Jon
Cone's neutral K7 inks.  Like a recent poster, I've been getting
better prints with EEM, which I use as a proofing paper, over the HPR
which I prefer to use.  In my case, I find the HPR prints somewhat too
dark, and in some cases the prints are actually wavy in the inked
area.  Does this mean (as I suspect) that the canned QTR K7 profile
isn't working for my printer, and that I need to work on ink limits? 
Is this likely solely an ink limits thing, or could linearization be a
factor too?  All this is pretty new to me (I was using ABW and K3 inks
before), and the new settings are just a little befuddling.

Thanks in advance,
