QTR-Quadtone RIP

Keith just to be clear, you have to remove the linearization first then generate new curve, print your wedge then put the new linearzation in, then generate your final curve set. Is that what you did? mike

Determined ink limit,etc. Selected an exisiting curve to modify to determine tone,etc. In curve creation, I modified density and limits and printed out 21 step wedge after step wedge to get a nice, evenly graduated step wedge. After many iterations,I thought I had made a good neutral curve. I pulled up an image in PS and made sure it was a greyscale tiff, gamma 2.2 image. I then opened it in QTR, selected my curve and hit print. The tone was neutral but the print was light. What did I do wrong? http://docs.yahoo.com/info/terms/
