I understand Michaels concern.
Possible one could test ones own working materials. I for one would trust my own testing, but I would love to see some real “official” published materials concerning Alkaline Fixer.
It would make me sleep better.
I know that Maco who sells a neutral fixer (which formula I do not know) say you can wash the print in 16min.
8x2 min continues rocking in a tray.
That is short.
I have not asked them how they get to this short time.
