RE: a few questions - Fabriano EW and palladium
I haven't used this paper but I have tried to acidify other papers and I am
guessing that what you see are fibers or places that were still alkaline,
i.e. uneven acidification.
Only guessing here...
CHEERS!

Subject: a few questions - Fabriano EW and palladium
Hi all...
I have a few questions re using Fabriano EW with palladium. My previous
experience with using this paper for argyrotypes was generally very good.
I acidify with a 2-3% oxalic acid bath for at least 5 minutes, until no more
bubbles can be seen.
I coat with FO #1 and palladium, using no contrast agent. The digital
negatives I use have sufficient density for achieving a good print. Printing
on Platine in this manner has been successful, yielding a long-range print
tonality with good detail and color. I use an ammoniumm citrate developer,
rinse and then clear with a citric acid first bath, and successive HCA baths
followed by a water wash.
I just started working with Fabriano EW for palladium work, and the tonal
results so far are decent, however there is some yellow-gold speckling in
several .dark areas of the print. At first I thought it was a coating
problem due to sizing, and added a touch of Tween 20 to the solution, but
the yellow speckles still showed up.
Here's a scan of the problem:

Has anyone seen this before? I'd love some feedback on this...
Thanks!
