[Alt-photo] Re: Replacement paper for Arches Aquarelle

[Christina Anderson]

Gareth,
I experienced this with Aquarelle with no clearing. Some of the papers have spots of clear gelatin, looking like it is heavier in some places or something. We discussed this on the list over 10 years ago when Katharine Thayer was alive, funny enough! So I won't say "search the archives" :)
I was in grad school doing gum printing and noticed this weird spotty thing happening with Aquarelle so I held it up to the window and photographed it. The spots were invisible when the paper was dry so what I would say is don't worry about your process causing it; it is manufacturer-produced.
I put the spotty paper pic on p. 125 of my gum book in the Gum Wall of Shame :)
Now whether that would scare me from using it for Pt/pd I have to say it might...
I use either Bergger Cot320 or Arches Platine for pt/pd (also Crane's Cover and Weston but both are cream colored) but since both are expensive papers I usually recommend others to the students starting out with pt/pd.

> Hi All, I've been having some clearing issues with Arches Aquarelle for a while now when platinum printing. I'm having to clear first in hydrocholoric and then EDTA to remove the remaining ferric. This is causing a discouloured mottling in the paper which is only evident while the print is wet and translucent or held up to light once it's dried. You can't observe it when the paper is dried otherwise. I was wondering whether anybody out there knows of a paper with similar characteristics I might change to that might fare better.
