itigal negatives for gum bichromate

[robertson parkman]

The existing curves for plat/pall result in a negative that is too thin for my gum bichromate pictures. I get better pictures ( more contrast) without any curves.. Does anyone have a bichromate curve for Photoshop? Thanks

That is difficult to understand. Negatives for Pt./Pd. printing are usually much to heavy and contrasty for gum negatives.

What printer are you using? It may be that the inks of your printer do not have much transmission density in UV.
