Digital BW, The Print

Hi,
I've always left my Ultrachome matte prints for at least 12 hours before framing or sleeving.

Is there any rule of thumb about how long one really needs to leave a print before sleeving or framing?

I suppose humidity would be a factor.

(The truth is I'm dying to frame a print I did a few hours ago.)

thanks,
Richard

I've never heard of one, and if anyone has scientific data I'd love to see it.

Based on what I've seen and measured I think 24-hours is 
best--minimum. If you're a paranoid wait 96-hours, but I think 
anything beyond that would be splitting hairs.

Most definitely. With high humidity (in the 80s and 90s) I'd wait a 
lot longer, but then I wouldn't want to store my prints in those 
conditions...

Cellulose appears to act like a sponge for the glycols that cause the
out-gassing with glossy (barrier) papers.  As such, in addition to air
drying, leaving the print pressed under some plain paper over night will
soak up a fair amount of these chemicals.
