I've heard very different opinions as to archivability of dry mounting fiber base prints, even in pervious threads I've read in this forum. I currently dry mount all my Fuji Crystal archive paper color prints and prefer the print to be perfectly flat. I'm just now starting to get nice fine black and white prints on FB from my darkroom that I would like to frame. Does dry mounting FB paper really affect it's archivability? What about spray mounting and other "archival adheisives" if there is such a thing? I know that photo corner mounts are the safest, but I (and I'm sure alot of other's too) prefer the print to be prefectly and completely flat under the glass.
