I don't know about VDB, but cyanotype is damaged by alkali -- ie.,
"buffering." I believe that in long-term storage the environment matters,
not just what is actually touching the print. (The wood of the drawer, the
interleaving sheets, etc. are all mentioned as risks.) Will you have
separate storage for cyano and VDB? Will you never forget & put that
exeter board in the wrong drawer? I find that once it's out of the pack,
or gets recycled, hard to remember, which board is buff & which not.
I once tried to reduce a palladium print by HEAVY doses of acid. It
didn't. I don't think I tested VDB, has anybody? Cyano loves acid... gum
I think OK if the pigments are archival. In any event for what it's worth
(if anything), I store gum, VDB and cyano separately -- and wonder if
anyone on list can comment about virtues of buffered mat boards. I seem to
recall mention that it was relatively irrelevant.
