QTR-Quadtone RIP

When you print a target for either QTR linearization or Create-ICC you
must select "No Color Management"  (previous versions said "Save As 
Source").
Without color management the source target embedded profile is not used
so its not important.   (It is important that you don't convert it in 
any way.   The
K values should be 0,5,10,...90,95,100).

The resultant ICC is not "for GG2.2" or anything else.   It's just a 
function of the
output driver.   The idea of CM is to be able to convert any source 
profile into
the output printing profile.

The Gray Matte ICC profile is a generic ICC that matches the standard 
linearization
that QTR uses.  So it's a pretty good match to any QTR generated curve. 
   I think
it's probably fairly good with the piezo K7 profiles but they were 
created by piezo
and potentially are slightly different in linearization.
