QTR-Quadtone RIP

Hello,

I am trying to use the Quadtone Rip, but the prints are coming out way
too dark. In the print dialog I selected No Color Management. The
prints looked the same when I selected Printer Manages Color. I'm on a
Mac with OS X.4.1 and am printing out of Photoshop. I'm not sure which
version of the Rip I'm using (I've had it for several years) and don't
know where to find out, but I don't think that's the issue. I think
I'm just selecting the wrong settings.

Thanks,

Avebon
