The problem can also be worse if very high sugar concentrations are used in the glop; the gelatine layer is almost 'softer' then and more prone to washing away in development. I have also had more issues with thin, highly pigmented tissue, rather than thick tissues with low pigment concentrations, I have assumed being due to less gelatine being needed for the highly-pigmented case and so the highlight layer is very thin.


Best regards,

I was just thinking about that. So if instead of using B&S's tissue (which is great to start with, but thin and very concentrated in pigment AFAIK) I made my own glop, thicker and with less pigment, would that help?

The fact is that my highlights are REALLY bad sometimes, so I cannot really blame it completely on the tissue. I can't imagine B&S selling a tissue which yields such bad results for reasonably processed prints.

But, trying to rule out all other factors, I tried acidic mating bath, double hardened substrate gelatin, even fixed out silver photo paper. The highlights are still being washed off. So I will try brewing my own glop next.
