QTR-Quadtone RIP

Thanks Duane, I'll give that a try. I'm trying to accomplish a few 
things here: create a dot pattern, make the inks as opaque or UV 
blocking as possible, and add a second color to the matte black ink, 
both for UV blocking qualities and to make the ink adhere better on 
the transparency film. 

The only part of your directions I'm not clear about is "copy it's 
curve (yellow ink) from the K ink"? I'm not applying any custom curve 
or linearization that I know of to the K ink, so what am I 
transfering over?  

Best, David.

If not, lower the overall limit, slightly reduce the yellow limit and 
try again. Repeat until it works for you.  Hope this is of some use.
