QTR-Quadtone RIP

Thanks.  I learning things in leaps and bounds.  Unfortunately since
I'm trying to create curves for a 2100 I can't use yours.  However I
can use the file created by Scott Schroeder in the files section.

A couple of questions:

(i)  Did Roy ever create a way to extract the curves from a .quad
file, as it was suggested that he was going to do?

(ii) Carl - in your definition file I see that you've specified some
parameters like 

GRAY_HIGHLIGHT=4
GRAY_SHADOW=4
GRAY_OVERLAP=5
GRAY_GAMMA=1

and

TONER_HIGHLIGHT=2
TONER_SHADOW=2

Do these actually do anything when you've specified a curve?  If so,
how did you choose them?  Howard in an earlier response said that
"None of the gray curve or toner curves facilities are needed as you
can make all those adjustments with the shape of the loaded curve",
implying that they either not needed or not used.  

Sorry for all these questions, but I'm trying to limit the amount of
blind speculation and testing that I am about to do.  It pays to do a
little research and testing before starting to burn ink and paper, and
in order to minimise the loss of sanity.
