Stephen, is this manipulation specific to Ilfoflex (not easily available!) or could it work with Crystal Archive, be it Type I or II? I'm still interested in this process. Could you provide more detailed information?
the other papers are a lot harder to control the contrast and colour with, they also have chemical issues with consistency and some papers get an odd mottle though them. The Ilfoflex is by far the most stable and consistent for Ra-4 reversal and with its high gloss using the same base as Ilfochrome it has a very similar feel.
I strongly feel the only way forward for ilfochrome in analog is Ilfoflex reversal.
