If you're editing in Gray Gamma 2.2, just use my curve for printing; probably no point in making your own. You can tweak the curve if you find it needs it, but if your system is calibrated you'll probably find my curve works well for the vast majority of shots. Be sure to apply the curve only to a printing copy and save it as such -- like with QTR in the name. Don't flatten and then proceed to edit the file with the curve on it.
You could have the curve on a layer, but I prefer to just apply the curve to a final saved working file, save a speical printing copy to the Desktop, drag and drop that into QTR, and then drag the QTR printing copy to the trash to avoid confusion.

Hi Paul,That helps a lot. I haven't finished creating my profiles for Hot Press Bright and have been using the curves for Exhibition Velvet instead and I'm getting some very fine prints after applying the GG22-QTR curve Would I see a 'better' result if I create my own curves ?PaulPaul________________________________________________On Wed, May 28, 2014 at 2:43 PM, Paul Roark roark.paul@...

QTR prints with a very linear (straight-line) Lab-L. Gray Gamma 2.2 compresses the deep shadow tones. See the graph at http://www.paulroark.com/BW-Info/Lab-L-QTR-v-GrayGamma-2-2.jpgMany soft proof (In PS: View>Proof Setup>Custom [insert ICC in "Device to Simulate"]) their images on the monitor by using an ICC. The QTR download has some canned ICCs (Lab L simulation only) and Create ICC-RGB can make a custom one that also includes the color information.I use another technique. I like to keep my files in the rather universal Gray Gamma 2.2, so I edit in that space. Then for QTR I apply a curve that adjusts the values. I believe my curve can be found at http://www.paulroark.com/BW-Info/Roark-QTR-ACV.zip . Or in most of my Profile zip files.Hope this helps.PaulOn Wed, May 28, 2014 at 9:46 AM, 'Lutsky, Berel' berel.lutsky@... [QuadtoneRIP] <QuadtoneRIP@yahoogroups.com> wrote:
I believe that there is a step-by-step for this on the northlight website, but you can get very close to a BW soft proof by editing in Gray gamma 2.2, on a calibrated monitor, this will give a good indication of the tonality, shadow detail etc. it will not show you any effects of toning -
