QTR-Quadtone RIP

I apparently was making a mound out of a molehill...I have a reasonable understanding of 
QTR profiling now.  Pretty simple now that I have created my first profiles.    I was 
confused by reading the scattered documentations, which to my mind makes this more 
complicated than it really is.

I hope someone will answer a few more questions.  I did not get any answers to previous 
questions...apparently they were just too stupid!!!  Sorry if my questions were/are foolish.

I am using OSX.  Here are my questions.

1.  There is a droplet, DropQuadProfile.  Current version does not seem to function on 
Leopard.  Do I need to use this?  What I have been doing is simply editing the text file, 
putting in the appropriate profile folder, and running the terminal script to reinstall the 
profile.  Appears to work fine. Am I missing something?

2.  My assumption on linearization is that if I make some changes, ie add a toner curve, 
that I need to print the modified curve/step wedge  without any linearization values in the 
installed text file.  Is this correct?  I assume I would not get a correct linearization if the 
modified curve has any linearization text.  Please confirm that I am correct.  Once I have 
read the 21 step, I simply paste in the linearization values, right?...and reinstall to have a 
linearized curve.

3. I am still wondering what .quad files are?  They are in the Cone Ink areas.   Just curious. 
I would like to look at the text values, but have not found a way to view these curves.


Thanks for your patience with me.
