Digital BW, The Print

Wondering if there are any avid Epson 7600 users that have gone 
through the process of of profiling and working with the PK inks with 
QTR.  I'm just getting started, and would like a mentor to talk 
through some of the basics.

Printed the 100StepWedge using Premium Luster photo paper and UC-NoK-
EPhotoPaper-Neutral profiles.  Noticed 1 is slightly less
than "white", and 95-100 came out of the printer wet with no
discernable change in tonality.  Would Ink Limiting reduce this over
inking tendency?
