Terry, could you explain a little on this? Did you mean you never found the
need to add glyoxal or formaldehyde to the gum solution, or did you mean that
you never needed to size your paper (with glyoxal or formaldehyde) for gum
prints?
The context seems to suggest the former, but if it is the latter I would be
very interested to know if you size your paper at all (esp. for multiple
printing). If not, what kind of paper do you use?
Thanks a lot in advnance!
