Re: [QuadtoneRIP] Re: Prints too dark from QTR, what next?

On a related note: I am setting up for digital negatives. My photoshop default space is indeed dot gain 20%, and I have read in the 21 step wedge that is included in QTR (which is untagged), and inverted and saved it for my experiments. The saved version is still untagged. Sample values of the steps have the right percentage black using the eye dropper.

Should I have done something different? Does my default working space matter when I read untagged files? Should I have converted the step wedge to gamma 2.2 before inverting and writing it? This is of course all in the context of printing the file through QTR (windows version).

I am realizing that there is a lot I don't know about color spaces for b&w printing. Is there a book someone can recommend that gives great background for someone that wants to understand how to set up the best possible printing flow?
