Hardner Formula(s) For TF-5

[tgtaylor]

Anyone aware of formula's for hardeners that can be used with TF-5 fix? I have some prints that I would like to sepia tone and would like to use TF-5 instead of buying another fixer w/hardening.

Thanks,

I have some sealed fixer that came with my kodak fixer. You can have it.

Thanks but TF-5 is an alkaline fix and I’m not sure if the Kodak hardener is compatible. There are formulas for hardeners in the Darkroom Cookbook for the Kodak type and I ran across another on PF’s website that may be suitable for an alkaline fix but I don’t have the 2 main I ingredients which, although inexpensive, I would have to order. Since the Kodak Rapid Fix if inexpensive, perhaps the best alternative of mixing it myself would be to buy a small package of the KRF with hardener to use with toning.

You can't add hardener to TF-5

You shouldn't use a hardener before toning, Kodak used to recommend a bath to soften the emulsion slightly before toning when a hardening fixers had been used.

Why on earth do you want a hardener for toning? Doesn't make sense to me.

Ian: Why do you say that? I'm not doubting you as I don't know.

Drew: Toner (Sepia) softens the emulsion and is recommended when fixing after toning.

Hardening can be patchy which normally doesn't matter but can lead to uneven toning. I did some serious commercial research into toners in the 70's &80's and never used a hardening fixer.

If you have used a hardener a pre-soak in a mild Sodium Carbonate solution 2-5% is recommended. followed by a short wash..

Ian,

I will be toning with PF's Sepia sulphide toner 221. According to PF, "the sulfide bath will soften the emulsion of the print. Therefore, it is advisable to harden the print before it is dried. You may fix the toned print in a fixer with hardener (Cat No. 03-0146) for 30 minutes, with a 10 minute wash to follow." That fixer uses ammonium thiosulphate but also acetic acid and TF-5 doesn't use acetic acid.

A Sulphide sepia toner won't be a problem, just be careful as you should be anyway even with a hardener.

I don't us PF but some of their suggestions go against the norm, such as not using an acid stop bath with TF-4 & 5 despite the fact that the originator suggests youbshould.

Thanks,

Here is what Kodak has to say:

Fixing
Improper fixing is probably the major cause of stains in
toned prints. Use two-bath fixing for best results.
Note: We do not recommend using a hardening fixer for
prints that you intend to tone, because it will make the paper
emulsion less receptive to the toner solution. Use a
non-hardening fixer, such as KODAK PROFESSIONAL
Rapid Fixer Part A only. With some toners, use of a liquid
hardener, such as KODAK Liquid Hardener (CAT 146
4239), is required after toning. (See the instructions for
specific toners under Using KODAK Packaged Toners and
Using Mixed Toner.
