Digital BW, The Print

Paul I have not seen an issue with dimensional stability. You should not be
cutting your matte, backer, substrate, etc too close to the size of the
opening. Just like laying a tile floor, you need to allow for a bit of
growth and shrinkage. 

 

I don't think that OBA in a closed environment is going to show that much
change over time of several years, even up to 50. No data here to quote but
just a feel.  I'd be much more concerned with interaction between the
coating, internal paper make up, and inks and sprays, before I'd worry too
much about out gassing of the foam either. The more closed you make your
system, the more you need to figure out all the possible interaction that
can internally take place; beyond my knowledge of conservation to be sure. 

 

I forget if it was this list or Wide Format, but someone posted a link to
the Library of Congress site about archival framing. ???   I may be missing
a bit or a byte on  that memory. 

 

 

Happy new year!   may your printer never clog, your memory not need an up
grade : )  and your ink always land where you want it ; )

I've wondered about whether there might be outgassing of the foam and
differential expansion between the foam core and matte print.

If there is differential expansion, due for example to humidity changes,
I think the print might show more waviness if it is just mounted with a
couple of tapes at the top.
