yet another question about viradongreenspun.com : LUSENET : B&W Photo - Printing & Finishing : One Thread
i had success using a sodium sulfite solution to stop viradon and prevent post-toning, but i've lost the post-it note with mixing proportions. it was something simple, like 8 tablespoons per gallon or something like that. can someone repost it?
also, a previous poster mentioned going straight from fixer into viradon? is this possible? i'd think putting a fixer-soaked print into viradon would cause a huge mess.

Eight tablespoons per gallon should do it. Don't go directly from the fixer to the toner. Rinse the print in water first to prevent nasty foam and toxic gas.
I have an old Agfa photo-lab book from 1942, and it mentions Viradon, so it's an old toner indeed!

Agfa's recommendation is 10% i.e. 100 grams per litre of water. I have heard of people using 20% solutions with no trouble.
