Anyone know the washing procedure for Fomatone when using HCA? Can’t see it’s mentioned in the data sheet?
Tanks!

(Have searched the forum for this information, but can't find it)
 
Fomatone with hca is the same as any other paper,I wash for around an hour after hca,but I tend to be cautious,you should in theory be able to wash the paper for 20 minutes or so after using hca,Richard
 
Over washing may not be a good thing as small amounts of thiosulphate left in the paper are reported to be beneficial to the print. The best way to work out your appropriate washing time is to use the HT Hypo Test Solution.
 
Thanks to both of you.
The latest procedure from Ilford says 1 min rapid fixer and 1 min Hypam fixer, then 5 min in running water, 10 min in Washaid (HCA?) and then 5 min final wash.
That's pretty short, and I was wandering if I dare to use that procedure for other papers and chemicals?

I'm surprised that someone has found a fix time of one minute for fibre paper - that would be resin-coated sort of time I think.

EDIT: Then I looked more carefully and found that for double strength (1:4 instead of 1:9 dilution) that is indeed the Ilford time. Apparently intended to reduce the time for 'dirty' fixer by-products to be absorbed in to the paper base, and therebye reduce the washing time too.

The Ilford documentation for washing after fixing states....

Using ILFORD WASHAID reduces the washing
time thus saving time and water. Wash the prints
for 5 minutes in running water above 5oC (41oF),
drain off the excess water and immerse the prints
for 10 minutes in a dish/tray of 1 + 4 WASHAID
at18–24oC (64–75oF). Finally, wash the prints for
5 minutes in running water above 5oC (41oF).

Hi again;
Ilford saye to minutes. One minute with 1 min rapid fixer and 1 min Hypam fixer.

Fomatone MG you have in Fomatone PE/RC MG (331, 332) and you have it in Fomatone Classic (Fiber) 131, 132.

The PE/RC papers you can wash in two minutes after fixing.

The fiber papers you have to wash for 5 minutes, then HCA for at least 10 minutes and then you can have the final wash for 15-20 minutes.

Having a strong fixer (1+4) will shorten the fix time too and a quicker removal of the fix when washing.
You can also use a 2 bath fix system to improve the fix time. 2 grams/litre Ag+ ions is the absolute limit for paper fix.

best regards,

Robert

Hypam is rapid fixer. Ilford is talking about a two-bath fixing procedure in film-strength fixer. You don't have to use different rapid fixers. Two-bath fixing for 1+1 minute is sufficient to fix Ilford papers. This may not be the case with other papers. Only a test will tell.
 
Thanks a lot from all of you for your answers.
I have reached to the following conclusion.

(I was referring to the fiber paper)

I’ll use the fixing recommendations from Foma, 1, 5 min in fomafix, strength 1 + 5. But divide the time in to in two fixing bath.

  • Fix for 1,5 min (in to baths)
  • 5 min in running weather
  • 10 min in hypo, and then
  • 15 – 20 min in running wather.
Thanks again!
 


Consider a slight modification:

  • 1 min in Fix1
  • 1 min in Fix2 (less than 1 min in each risks uneven fixing)
  • 5 min in running water
  • 10 min in HCA (not hypo, hypo is fixer)
  • 20-30 min in (slow) running water

For better archival processing, you need to follow up with a toning bath (selenium, sulfide or both).
 
What agitation, if any, is recommended in the HCA solution?
 

Is that 1 minute in fix1 & 1 minute fix 2 in film strength fixer Ralph? I understood Ilford's recommendation for a single bath fix was 1 minute in film strength fix or half minute in fix1 & half minute in fix2, also at film strength.
