QTR-Quadtone RIP

Hi Tom,

First, are you confident in your monitor calibration?  Second, you say that you "assigned" 
gg2.2.  Did you really perform an assign or a conversion?  There are very few cases when 
you would want to do an assign - especially with a RAW file should have entered PS with 
an embedded ICC profile (probably some form or RGB).  When I have had problems like 
that with Piezo products, it was usually a profile problem.  If your printing from PS, select 
"no color management" and within QTR select the correct curve.  (I assume you have 
installed the EEM curve for NK7).  Third, are you confident of your monitor calibration?  If 
you are not profiling your printers output with QTR's QTR create ICC, then you are not 
running a closed loop system, and you will be VERY dependent on your monitor.  I highly 
recommend reading through the archives about using a spectrophotometer or a 
densitometer for creating B&W ICC profiles with QTR create ICC.

Good luck!

Josh
