Joao,

You have received some good suggestions, but we are "guessing" at your
problem. Perhaps if you give more details (the proportional of the
ingredients in your formula, what does the print looks "ok" means, highlight
ok? shadow ok? etc), it will be easier for us to help.

With alternative processes sometimes the logic runs differently from standard
silver paper. For example, with gum and the same mix, I can coat ***very
slightly*** thicker (by feel) to get a deeper tone, but if I coat a little
more thicker, then I get a much lighter tone because the exposure cannot
reach the base and so the image wash out too easily.
