     I have used QTR and like it very much! (thanks Roy!!!). 

     But, I tried to "re-linearize" once before and it gave very strange results. I printed a 
21 step scale with based on one of the files that came with the software, read it with 
my eye one and put in the data to the curve file and ran it. Then I did it the preceeding 
again, substituting the new info for the "linearize" function at the end of the curve file, 
and the result was just crazy. The curve was unusable (weird tone progressions all 
over the place)

    Since then I've always begun from a "clean" curve file (namely one of the files that 
come with the software) and I linearize *only once*. If a curve gets weird (from 
strange readings near the black end of the scale for instance) I start over(which is kind 
of a pain, but not terrible).

    Is this the right way to do things???  Can I get the new software (I have an 1160) run 
a step scale with a curve I already use and then read and re-linearize that? Or am I 
right to begin with a fresh curve file every time?

TIA

ps. Roy, thanks again. Your efforts have been a tremendous contribution to the Mac 
-Quad printing community.
