Re: Another Ziatype question

Ok, things become clear now... Thank you very much for reminding Clay's
article!

What do you think about including a trace amnt. of 1% oxalic acid into
sensitizer? (for instance: 1 drop = 0.05ml to 1ml sensitizer)

It seems that PH of paper and/or developer/washing water is very important
in Pt/Pd printing... It seems that I have to seriously study this issue.

Thanks,
Loris.

Loris and Christian,

Although I've never used Whatman HP, Clay Harmon writes in his article about
Gum over Platinum, that Whatman HP should be treated to a 1.5% oxalic soak
to prepare for palladium printing. I assume that may hold true for ziatype
printing as well with that paper.
