QTR-Quadtone RIP

Thanks so much Duane. That's the clearest, most straightforward
explaination of ink limit and density that I've seen, and it goes a
long way to helping me with this project. I've just gotten some sample
transparency sheets from two sources, so I'll try a few different
methods/colors for each.   

Regards, David.

> It might be helpful to just think of the limit as being the quantity
or volume of an ink that is put onto the paper or transparency, with
100% being the maximum you can put down, and the density as being the
maximum darkness of each ink. As you mentioned wanting the grainy or
dotty look since your use requires it, and given that you are Not
making reflective prints but . . . I think you want the maximum limit,
ie: 100% for both inks, at least initially. Density can be ignored . .
. at every point. You want both ink colors to be used over the entire
curve--not partitioned. Just call one color ink the K channel and use
the "duplicate the K curve" option for the other. You wouldn't have to
mess with changing the limit unless there was so much ink being
deposited that it runs or won't dry . . . .

an orange shade being best, though one would think yellow would be
suitable), to simply mix the shade you need directly from bulk ink and
only use a one channel curve from QTR from that point on.
