Hi folks, I have some very old ilfochrome paper that I would like to use for carbon transfer support. I have some chemistry as well. What would be the easiest way to process the paper so I have a nice white piece of paper when I'm done? Thanks for any help.

Erik
You give it strong white light exposure and then fully process it. But then you will still have
a Ciba emulsion which is inherently a bit soft and fragile, so might be questionable for your
actual purpose.
Thanks Drew,
Do you know of a way to do it when I run out of my p30 chems? I have sulphuric and hydrochloric acid available to brew up a bleach if needed.
I think I can safely handle the emulsion as there is not much disturbance during the carbon transfer process. I think it might be a nice support for a high relief print.

p-3 pro chemistry is probably still available special order. Don't know if you'll get a residual
color cast from the paper being old, but you could just over-bleach to get this out. For
your use an ordinary strong b&w dev like Dektol might work. The fix was just non-hardening
ordinary Ilford fixer. Bleach is obviously the problem. It's mostly sulfuric acid, but with a
bunch of other nasty stuff in there too. You could order in just extra P3 bleach provided
you have a shipping location. P30 substituted sulfamic acid crystals, so was safer to ship.
