Re: Canson Fonteney and gum printing

Hello Cor,
Fontenay is a sold as a 'hybrid' surfaced paper, one side somewhat
smooth the other side rough. I allways print on the smooth side.
I'm using fontenay quit often, also in my workshops. I buy 50-100 sheets
at once so my batch might be a bit older than yours and I don't know if
it has changed. I allways preshrink and gelatin/glyoxal size. Take care
the preshrinking water is not too hot (keep it under 40 degrees C)
otherwise the factury sizing comes of as a slimy substance. This also
happens when you keep it in the water overnight.

What you discribe sounds like a form of abrasion or a problem with the
internal sizing. I think a hardened gelatin size will solve your problem.

Can't say that I like that effect.
