Previously I've used the traditional 2-bath 1+9 dilution approach for fibre base printing for the most part. Reviewing more recent ILFORD pdfs I see they're still recommending their 1+4 single bath fix for printing; however at a capacity of 10sh 8"x10" per litre this means a lot of fix used per print due to silver accumulation rather than fixer capacity; although I understand the ILFORD sequence is partly based around the idea that a shorter contact time means less fixer to wash out of the paper, in conjunction with a clearing bath.
The HYPAM documentation (which should hold for other rapid fixers of similar type) appears to give a fixer capacity of 5ml per 8"x10" FB sheet. Multiplied to a working solution this would suggest 1+199 dilution, i.e. 5ml fix concentrate + 995ml water. Obviously this technique has greater practical application for making larger prints with a single tray method, e.g. 20"x24", or 30ml fix + 1970ml water.
I've read references on APUG from 5 years ago, some associated with my own postings on fixers but nothing more recent. Is anyone here familiar with using fixers at high dilution?
