QTR-Quadtone RIP

Thanks again Roy. Good to know about the warm curves, since I didn't 
even look at them, assuming they wouldn't be all black inks. That's a 
good place to start. 

I'm printing to transparency sheets with the intent of using them to 
make photopolymer plates for etching. The usual photo aesthetic 
doesn't apply here, since what creates a good plate and print--with 
contrast and tonal range--is to start with an image where the curve 
has been compressed and flattened. And it also needs to be printed at 
720 DPI output. 

In short, it means a lot of experimenting and tweaking.

Best, David.
