Re: Gum on Azo?

Dear Swami,

AZO is a single weight paper and would probably be difficult to work with as a substrate for gum. Also the dried print would need to be flattened in a dry mount press before coating with gum and each additional gum coat would probably require re-flattening sice the paper is so thin and prone to curl.

If you are printing 8x10 negatives you will need to purchase larger sheets in 8x10 to coat gum on. The next size up from 8x10 these days in AZO is 20x24 if I remember correctly.

So you may want to consider another silver gelatin paper or perhaps Centennial POP for their heavier weight paper base.

Subject: Gum on Azo?

I have a project where the sharpness of the prints is paramount, and my
intention is to shoot 8x10 (I have a 480mm Ronar in a Prontor
Professional 3 shutter I have been itching to use) and contact print
those. I was thinking of trying Azo, or another manufactured paper,
reasoning that that would best retain the sharpness I'm looking for. The
only potential problem is that I would like to do a single-gum layer on
top of the prints. Would Azo hold up in the washing, or is there
something about the paper that is incompatible? If not Azo, is there a
manufactured paper someone could recommend for a project like this?

Thanks.
