QTR-Quadtone RIP

The issue with the K7 inks is that you don't have an easy starting place with
the Cone curves (QTR profiles).  So to make new ones, you need to start from
scratch as opposed to just re-linearizing them.   In practice there's almost no
good reason to bother.

If you do want to do some customization the most useful thing to do is make
a custom grayscale ICC profile.  This gives you all the color management
features in Photoshop -- softproofing and a print profile.  In fact
the print profile
gives you very similar functionality as the QTR profile re-linearizing
-- but better.
Because the ColorManagementSystem can then match the embedded file
profile with the driver/ink setup.   See Amadou's Level 2 for this.

(as has been said before, starting at Level 4 will almost certainly give worse
results than starting at Level 1 and progressing.)  I think you really
need to have
the visual understanding about why you are customizing.
