QTR-Quadtone RIP

Hello Jeff.
 Actualy, if everything is calibrated and profiled properly, and you
use the ICC profile for softproofing, it probably doesn't matter what
you use as the working space. You are visually adjusting the file for
what the output will be anyway. The point of the softproof is to be
WYSIWYG onscreen. Since Roy used Lab as the basis for linearization of
the printer curves, it isn't a surprise that it might print ok
directly from Gray Lab. The match should be as good as the printers
linearization is.

 Why do you use perceptual intent with B&W since nothing can possibly
be out of gamut? (Not  a criticism, just curious.)

Regards
Duane
