QTR-Quadtone RIP

Hi David. As you have had no reply, I'll make a suggestion. No
guarantee comes with it;) Why don't you simply try an overall ink
limit of 100% with 0% boost. Limit your yellow ink to 25% and copy
it's curve from the K ink. Call both of them 100% density.Go ahead and
print a scale and see what it looks like. Since you are actually
wanting a transparency, the usual d'max issues probably won't apply
here. You're just trying to get maximum transmission density so the
more ink the better. The issue you might have is the dot spread on
your transparency material if there is too much ink going down. Look
at it with a loop or magnifier to see if you have nice crisp dots. 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.

Regards
Duane
