The ICC profiles are used in the Preview window for the Print Space.  This is
where you'd use the generic Gray Matte/Photo Paper profiles I had before or
you can customize an ICC profile with QTR-Create-ICC.   This is where the
color management system controls any conversions embedded profiles.

The curves and blending that have always been in QTR are at a lower level 
and only are entered on the QuadToneRIP print dialog page.  Ideally you would
select all these driver options when making the ICC profile for above.
