I haven't used the negs to print in the darkroom. From experimenting with a
few different curves and tweaks I discovered that the silver curve worked
best for me. Judging by the way this curve pushes tonality toward the
mid-tones I presumed it would work well with gum. I should perhaps point out
that my Metal Halide lights are quite contrasty so I seek to produce quite
flat negatives. Different lighting set-ups might need a different approach.
What I like with the Lyson inks is that I get a nice neutral neg but with
the density I need for gum printing. And I don't find the results grainy
either. Sam Wang has a curve for gum that might suit your needs.
