How archival would......
How archival would a fibre print be after the following:
3 min fix
rinse 3 min
HCA 3 min 20 deg.
Wash in tray with Kodak syphon 15 mins
I know this is a long way from what is recommended for proper treatment of FB prints, but I'm just curious.
Is this OK for work prints?
Does anyone have any idea what sort of lifespan they would have?
I have piles of FB work prints and contact sheets from the early 1970's for advertising and material from the old family company (bicycle manufacturing of all things - but there's some great shots) - I can't believe they received full archival treatment? and they look fine 30 odd years on.
Processing for Permanence
It's hard to tell what results you will get since you do not list the type of fix you plan to use.
With rapid fix at the "film strength," three minutes is too long!
With conventional fixers, three minutes is not enough.
You can use a rapid fix at "film strength" for one minute and get a good fix. However, the capacity is greatly reduced. I use two weaker fixing baths (rapid fix at "paper strength") for 1.5-2 minutes each. This isn't long. Often, I wash and dry after the first bath and only second fix the "keepers" later, in a "toning session."
The wash is your main weakness here. 15 minutes won't do for permanence. However, it will do for work prints you don't plan on keeping for long. And, you can always complete the processing later by soaking, second fixing, hypo-clearing and washing as described below. Just don't expect them to last a long time if you don't... And, don't sell them as art prints to anyone!
It's not clear from your question if you are addressing your own work or want to ensure permanence for the old family pics. If your concern is to preserve old prints, you can simply re-fix and re-wash them (even tone them if you like).
Simply soak for five minutes and run them through an "archival" process.
My work-flow for fixing (based on lots of research and personal preference) is:
1. Place wet print in a rapid fix mixed "print strength" for 2 minutes (this would be Ilford Hypam or Kodak Rapid Fix 1:9 or equivalent).
2. Transfer print to second fix for 2 minutes (same stuff). The capacity for fixing like this is about 25-30 8x10s per liter (each bath being a liter for 2 liters total). After capacity is reached, mix a new second fix and make the old second fix your first fix. This cycle can be repeated three or four times before mixing both baths fresh. Usually I just use fresh for both. Fixer at this dilution is cheap.
3. (optional) Transfer print directly to selenium toning bath. Tone to desired image change/density increase
4. Transfer print to a hypo-clearing bath. Agitate in this bath for 10 minutes (yep, I know its longer that Kodak's recommendation but there is some science to back up the longer time, and it certainly won't hurt).
5. Wash in archival washer for one hour.
6. Squeegee and dry, face up, on screens.
This should result in very well-processed prints.
Hope this helps,
It's all guesswork unless you test. For me, I'm finding that even with HCA, 15 minutes with a Kodak syphon would not be long enough, at least when washing multiple prints. I'm using Formulary's residual hypo test. Presumably there are similar products availble from UK suppliers.
I'm in the processing of ditching the syphon for some other (undetermined as yet) kit.
If someone has an archival washer lying around they'd like to sell...
What happened to the experiments some years ago that showed too much washing was bad?
Is your goal just to shorten your processing time? If so, maybe you should look at using Photo Formulary's TF-4 fixer. For fiber, the fix time is only 60 seconds (but I err on the side of caution, and use a two-bath system with the paper in each bath for 45-60 seconds), and you don't need an HCA step. After the fix I rinse the prints for a few minutes then store them in a tray of water until the end of the session, when I wash all the prints at once.

Water quality should play a large roll in washing effectiveness. All water is not the same. Hard water will not wash as quickly as softer (low mineral content) water. I would not generalize on someone else's washing results unless you are using the same water.
I found that 30 mins soak (4-5 changes of water) after 5 mins in HCA worked well. I suspect you may be surprised how long a print will last after 15 mins in running water; but as others have said, for how long is impossible to say. In practice, I wash for 1 hour with 6 changes of water.
However, the major problem that occurs to me is that you will be putting insufficiently washed prints on screens, in storage boxes and elsewhere and so potentially contaminating subsequent fine prints.
Good luck, Bob.

As well, they state that when using a HCA agent, 5 minutes wash running water, 10 minutes HCA, and then 5 minutes wash is sufficient for an archival fiber print. The print is fixed at a point, from then on you are just letting it soak in fixer that you will have to wash longer to get out. I've never had any reason to doubt them - after all they are the well paid scientists.
If they're just work prints, then don't they only need to last for the night or a few days?

There is one over-riding criteria for 'archival' or 'optimal'
which has not been mentioned. That criteria concerns the
fixer's silver level. Archival or optimal, that degree of clean
begins with the fixer. Very low levels of silver must be
maintained and the usual way to do it and achieve
any reasonable mileage from the fixer is to use
I'm able to achieve archival or optimal results from one
fix by using the fixer very dilute, one-shot. Dan
