QTR-Quadtone RIP

Hi Roy

I see that IJC/OPM only has blending via TIFF alpha channel for the PC
(i.e. not the Mac). As a PC user, I guess that wouldn't be a concern
for me. However, as a dual platform application I could see it would
be a problem for implementation within QuadtoneRIP. Too bad.

I think we can already do density based split-tone by creating an
appropriate split curve and blending it with another (non-split)
curve. More flexibility in the current curve blending scheme would
permit the creation of images that are not currently possible with QTR. 

See below...

I'm not sure what you mean here. Do you mean 3 curve pairs
(highlights, mid, shadows) and 3 blends (one for each pair)?

Well, it would be consistent with what QTR users currently do and make
it easier to do density based split toning. I'd like to do more with QTR.

Thanks for responding promptly, even if it wasn't what I wanted to hear.
