Re: Dry-mounting gum prints

Most galleries/collectors will prefer museum board. There is perfectly
"archival" foam core, but it is the exception. That makes folks
"nervous" with foam core.

My complaint with foam core is that it often "depresses" under a dry
mount print.

If you vat gelatin size your papers you may (I have) problems with the
prints slowly (over years) un-mounting. I "assume" that the gelatin
sized paper is too "slick" for a good long term dry mounting. I didn't
see that on papers I brush sized on one side. My gum/mount experience,
both good and bad, is quite limited. I tend to corner mount.
