QTR-Quadtone RIP

Paul, et al,

You can use the Wide Gamut RGB profile - it's based off gamma 2.2 and will give the same results as using Gray Gamma 2.2.

If you purchase and use Roy's QTR-Print-Tool, color management with QTR is definitely simplified and you'll get more accurate results than printing through Photoshop.

I don't have a link to the original thread, but it's been discussed before on the message board.
