Thread: TF-4 fixer question

    TF-4 fixer question

    Hi,
    I am using TF-4 as a fixer for my prints. They claim that hypo clearing is not necessary. Is this correct? or should one still clear with hypo remover?

    Depends on how many prints I'm doing. If it's just a few, I wash a little longer. If it's a big session, I use Permawash to reduce my wash time even further, since I don't have a lot of wash space.

    I'd do a residual fixer test to see if it's necessary with your practices. Last time I tested it without Permawash, it showed the fixer was gone in about 10 min in my 16x20 Versalab washer using Polymax. I still wash for 30 min, though, mostly out of superstition.

    I'm doing three other things right now but you don't need HCA because TF-4 converts to the end product of fixing directly where traditional fixers that need HCA do not. Standard fixer converts silver to a compound that is difficult to wash out and then HCA converts that compound to a compound that is easier to wash out. Sorry I don't have the compunds themselves but that is why they say you don't need to use HCA.
