    Paper for Ziatype

    Do any of these papers need pre-treatment before using for ziatype?

    Socorro, Platinotype, Cranes Kid, & Cot320. Recommendation appreciated too.

    Thanks!

    The last two do not. As I understand it, Platinotype is similar to COT320, but I've not used it.

    Those will all work. Some people treat Socorro with Oxalic acid for DOP palladium. And I don't think COT 320 is similar to Platinotype but is instead very similar to Arches Platine.

    COT320 and Arches Platine are both made by the same manufacturer. COT has greater texture than Platine. YOu will definitly need to treat socorro if you want a smooth print. It has a basic sizing that needs to be neutralized, when I treat it with hydrochloric acid, I can see the carbon dioxide bubbles rise from the paper. I imagine they are using some carbonate salt for archival properties. Given that this was supposed to be a paper specially made for pt printing I cant think of any reason why they do such a dumb thing.
    Cranes Platinotype needs no pre treatment, and I have no tried Cranes Kid finish so I cant help you there.
    Good luck.

    I use the Platinotype and it works well with Ziatypes. Both the bright white(think that is it) and the natural work well. I find when I print a colder image I like the bright white & with images that are more brown/sepia looking I go for the natural.

    I have used Cranes Kid finish..that's what the print was done on I sent to you Jorge...it is very thin paper (or at least what I got from Bostick and Sullivan) was.and while it might be easy to coat, it really does not work that well for Ziatypes (IMO-YMMV). COT320 and Arches Platine seem to work much better for the way my process works. Give both of these a try, think you will be happy with them...one note, the COT320 white, can be very 'White' so if you are looking for a warm tone, it might not be the best paper, there are way to many here that can give you a better idea of how these papers perform than I can. Listen to what they tell you..it is mostly from experience they speak...and hopefully you(we) can avoid some of the problems they have already encountered.

    Mike,

    Just a quick suggestion. If you have a paper that you like to print with, but it's too white for you, you can turn it into a warmer paper by tea-staining the finished print. I happen to like the color that Celestial Season's Earl Gray gives. Use very weak tea. One tea bag in 1 or 2 liters of water. Soak for a few minutes with some agitation followed by a final wash. Works great and makes your darkroom smell good, too. I don't suggest tea staining prior to printing because that caused fogging with some papers I tried.

    That is a great Idea, have you seen any problems with even stainning?

    Hence the suggestion to agitate. If you leave it in the tray and walk away for a while, you will likely get uneven staining.
