Adox Art Baryta, specifically for Kallitype/pt/pd

[Finn lyle]

So after scrounging for a bit it seems that there's been a lot of talk about art baryta but no real results to be found on its performance as a paper for kallitype or pt/pd printing. I just picked up a pack to try with kallitype and was curious if anyone else has tried anything similar with this paper?

UPDATE: after trying to coat a few sheets, it looks like the gelatin overcoat is not strong enough to withstand a few passes of a Hake brush- and the paper does not absorb liquid evenly at all (it will absorb the coating though!)

I thought it is not supposed to have a gelatin top coat. Is it not true?

Thanks nmp, that link has some really valuable information, interesting that the temperature effects the coating so much. I am worried that since (if there is even one) the gelatin overcoat is so thin that there is little to nothing to absorb the sensitizer. Ill give that method a try though.

Ok...I checked the Adox page....it looks like they do have a gelatin coating that they call "undercoat" - I guess thinking once you put your own emulsion on, it will become the undercoat or a barrier before the baryta coating. In any case, perhaps if brushing is too harsh - have you considered rod coating. Hardening the gelatin might be an option to try out.

One way to make the coating more receptive might be to wet it beforehand, perhaps with some T-20 added and dry it just enough to keep some moisture around. Kind of like wetting a sponge and squeezing the excess out. Then apply the sensitizer. That might help with the uneven absorption and blotchiness.

Would gum bichromate be more suited for this paper, I wonder.

Just some thoughts....
