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...
