[Alt-photo] choice of paper for Pt and gum over Pt prints - was Re: Re: Replacement paper for Arches Aquarelle

[Jean Daubas]

Hi all

At the beginning of the month, there was some discussion on our list about the choice of papers used for Platinum/palladium printing.
So, I think it could be of interest for you to know about the choice of substrate paper used for the Platinum and gum over platinum prints included in the new  Imogen Cunningham publication by 21st Editions.
It is Rives BFK and you will find an interesting review by David Chow of his visit of “21st editions” at London Art Fair 2014.
It is here on his blog “The Art of Platinum Printing”:

Happy to share with you, hope you enjoy,

Alternative cheers from France,

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.
