dichromate free copper photogravure

[Wayne]

Another process being done without the traditional dichromate. Still waiting for someone to lead the way for me and perfect dichromate-free bromoil

Ah... DAS.

I've started playing a bit with ferric gelatin again, but dichromate-free bromoil is definitely going to be challenging!

As i understand it, and my understanding is limited by the fact I've never done bromoil, among other things, is that the challenge is clearing the stain from DAS. I posted about a clearing bath for DAS-based gum diazo here https://www.photrio.com/forum/threads/bromoil-and-dichromate-replacement.146602/#post-2356533
but don't know how applicable that might be to bromoil
