QTR-Quadtone RIP

Thanks Tom. I realize this is a fairly specific application and not
one that's very common. 

Even though I'm still not sure what density does, I did create a QTR
curve that upped K to 80% limit, halved the LK density and limit and
turned off the LLK. I'm happy to report that this got me closer to the
results I'm after--I got a print with more in the midtones the lights,
and darks were not so bunched up. 

I'll keep tweaking both my QTR curves (now I'm not so nervous about
upping the K) and curves applied to the images in Photoshop till I hit
 on what I need. 

Also, the R2400, fine printer that it is, does not allow K only
printing. The closest it has is an Advanced B/W mode, but it gives you
no control of the ink set and also this mode prints at a lot higher
output resolution than what I need (which is 720 DPI). So it looks
like QTR is the answer!

Best, d. 

PS -- and still wanting laypersons' explaination of density. I guess
I'm a bit dense myself here.
