QTR-Quadtone RIP

I didn't investigate this...I simply used un-filtered white light.

Conceptually, it would make sense to use a lower-contrast filtration. Even when using the gray inks, there's still areas of ink surrounded by areas of clear film. I would think a hard filtration would emphasize this and a soft filtration would minimize it.

If that's the case, you could make yourself a Grade 0 profile and a Grade 5 profile for different visual effects in the print, while the overall tonal distributions would remain unchanged.

I may conduct that experiment myself sometime in the future (whenever that is.)
