Scanner negs need to be fully exposed for shadow detail, then developed to less contrast than that required for a diffusion enlarger. A condenser enlarger fills the bill or diffusion and one paper grade higher, probably #3. The problem with standardizing on 3 is it limits how much higher you can go.

I use Delta 100 developed to print on #2 with focomat ic or other condenser enlarger, scan with KM5400 original model.

Ideally for dual work flows, expose at 1/2 speed and develop 20% less. You will love these negs with full shadow detail and very fine grain. They will not look flat either.
