Re: Coating palladium ahead of time

Andy Schmitt

A few years ago, when I was still running the department at Peters Valley, Tillman Crane and I came across a complete Palladio kit buried in the back of the storage cabinet.
Since Tillman was giving a Palladium printing class at the time, it seemed appropriate we open it & try it. It worked delightfully. Unfortunately you couldn't really tune the base image since its pre-coated.
Tillman seemed pleased with the results so there's a bit of historical data for you.
Have a wonderful day all..

What I am about to say is not scientific proof, just examples from my experience. I sometimes get vertigo and it comes on rather quickly. My PT/PD prints are about 95% palladium and 5% platinum. A number of times, I have coated paper and suddenly had an attack of vertigo so I have had to stop work. I have exposed coated paper from between 24 to 48 hours later, but no longer than that. I haven't noticed a change in speed, contrast or fog but I have noticed that the finished prints looked warmer in color.

*****I do rehumidify the paper before exposing whether I have coated it an hour earlier or 48 hours earlier. I dev in Pot Ox at 40 C.

On another note, there was once the Palladio Company that sold PT/PD printing kits with pre-coated paper and packaged dev and clearing bath. This is how I got started. I made some decent prints with the pre-coated paper but not as nice as what I make now. So there must be a way to pre-coat and use later.

I now defer to those much more experienced in this to answer you further.

Hello everyone,

Does anyone have any experience with coating palladium and then storing the paper for later use? From what I understand it will fog if not exposed the same day, but perhaps am I wrong in thinking so? So i’ve never tried it… I’d love to be able to prepare 10 sheets at a time and not worry about having to expose them the same day.

Looking forward to your feedback!

Best wishes,
