Digital BW, The Print

Hi All -
Just a few words about mounting -
Within my knowledge, all of the sprays have some sort of lacquer or  
shellac base. There are newer compounds for spraying, but they
mostly will behave the same way when exposed to heat. So if one is  
serious about dry mounting with a Seal or similar press,
you should never spray the print first. Aside from that, there  
probably is not a lab in NYC (where I live) that still mounts prints  
with heat.
There are some very safe cold mounting processes, and they very often  
mount on archival "gator board". For large prints there's
a chrome roller unit that squeezes the print, tissue (which is 100%  
archival) and the gater board together. For one of my clients,
  I'll regularly have glossy inkjet prints (and occasional "C"  
prints) around 60 X 48 inches mounted on 3/16 inch gator bd, which are
  then framed by the client. BTW, Gator Board comes in thicker  
versions, as well.
For small prints one can do it yourself with a paint-on solution and  
a roller, but you'll have to research for the most archival of those!

Hope this helps.
