Paper for Kallitype or Pd/Pt print

[Andrew O'Neill]

I had success with Rising Stonehenge for Kallitype printing. I also use it for carbon transfer printing. It's cheap, too.

Another thumbs up for Rising Stonehenge!

I have a question about Stonehenge paper - do you pretreat it with acid?

I just received a fresh batch of it from B&S, and it gave a grainy, blotchy kallitype. I used the same procedure that gives beautiful results with Arches Platine and COT 320.

Thanks,

Mark

Yes, for Pt/Pd I acidify with 3% oxalic acid for 5 min and drip dry.

I've never had to pretreat Stonehenge in an acid bath but you can try it... or try putting a few drops of oxalic acid in the sensitizer before you coat.

Thanks, Denny and Andrew. I tried both methods tonight. 1 drop of citric acid (I don't have any oxalic) per 1 mL of kallitype sensitizer didn't work for me. Soaking the paper in 3% citric acid this morning then hanging to dry all day gave an improvement, but still a little residual blotchiness - maybe I didn't soak it long enough. Using the sensitizer with added citric acid on the acidified paper worked great.

It looks like this paper will work for me, I won't have to donate it to my wife's watercolor efforts!
