Determine the basic exposure for palladium printing

[sudek]

Loris,thanks much for the kind suggestions.But I think I shouldn't give up so easily after "torturing" you for such a long time.
I would post the good news when I have one.
Thanks again for all the warm-hearted help

I have also been following this thread and have found it very useful. I would like to commend Loris for his community spirit.

Hi Loris,
Sorry for the late report. I had surgery and just got back the experiment recently.
And good news finally. The exposure time is 7 mins 30 sec.
I know I could never have made it without your encouragement along and all your warm-hearted help.
Thank you so much!!!

Hope you're well now.

Happy to hear about your good results, I'm glad if I had provided the tiniest bit of help to you.

So, what's your verdict about your previous problems? How you managed to solve it in the end?

Regards,
Loris.

Hi Loris,

I'm fine now,thanks!

No doubt your help to me is enormous.I'll always be grateful for that.

It was solved by chance.Usually I would coat paper that has been exposed to air in the room for 24 hours(humidity is about 70%). Someday I was busy and didn't coat it till three days later. And the result was different. It seemed the problem was the humidity in the paper. Does it sound queer?

 

[Loris Medici]

Not at all, you need humidity to have good results with pd. I think we've talked about humidity before... (extending the coating solution with water etc. etc.)

Nice printing!

Regards,
Loris.

BTW, you may opt to add a drop of glycerin per ml of coating solution if you need to retain moisture within the paper... Try it. (Beware, that's good for Pd, not good for Pt!)

I'll have a try.
Many thanks
