Don, I don't know of any way to be sure a curve is right without printing it
with whichever alt process you are using. Also, it's important to include a
step tablet that has also had the curve applied so that you can see how the
tones print. Tweaking is usually needed, and the step tablet shows where
it's needed. You didn't say what process you are using. I went through
this for Van Dyke, starting with Dan's platinum/palladium curve also, and
had to adjust it three times. Good luck. Grace
