I have been formulating plans as I read more about papers and chemistry to try and resurrect this paper. So this evening I endeavored to try my new Eco4812 developer at a 1+10 concentration and try different development times as Wolfgang Moersch says this can improve contrast. I also mixed a 1% solution of Benzotriazole in alcohol which I would then add in successive amounts as I ran experiments to control the fogging.
As a reminder here was a print as developed in Universal PQ.
Note the border is gray and the low contrast. So with the new experiments I started with a a couple of test strips.
This was really exciting as the paper was snow white in the borders. This meant the …
