Paul,

Now that I have found the Load Curve and Point List tabs, can you 
elaborate a little.  I amstill unclear on what to do.  Do you use 
just those two points above?  And only for the black ink or for all 
inks.  I was under the impression that printing without any 
linearization data entere was the same as printing with 0,0 and 
100,100.  I guess that is incorrect?

I have read the following description on your website and it appears 
similar in many respects, but I didn't see a reference to the above.  

"QTR, 2200, 4K+, Matte BW, Carbon & general monotone inkset curve 
profiling"

Just a little confused, but your approach does seem to elimiate 
significant iterations and give a better result, so I'd like to 
understand it.  Is this only used for Quad inks, or can it also be 
used for a color inkset like the UC inks?

Thanks, Lou Dina
