Re: a few questions - Fabriano EW and palladium
Well I don't understand what these specks would be from, though...there are
not dense spots on my negative.
But because they are yellow, it would be easy to assume that it's a clearing
problem. However, all borders and highlights are perfectly cleared.

With Palladium and PotOx, I was NEVER able to adequatly clear regardless
of the level of pre-treatment in an acidifying bath. Your problrm sounds
like it might be a clearing issue.

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!
