I think I see the confusion.  You don't save the curves in
the Curves command.  The idea is to save the main file
with the curve adjustment in effect.  So you change the 
curve layer and finish, then you do a Save As for the whole file.
This is where you find the Raw format.  The raw format  of
the file shows what happens to all possible 256 gray values
during the printing process.

The idea is to get "quadraster" into the middle of the filter
pipeline.  The pstoraster being a shell script on my system
made that very easy.  I think there's two possibilities to make
this work.  First, it may be possible to configure the PPD
so that CUPS inserts quadraster into the pipefile, but that
may involve a new file type name.  Second would be to make
a new program (c code or shell script) that calls the two
programs with a pipe in between.
