    Plat/Pal printing bleeding!

    Hi
    When I develop Platinum/Paladium prints, my prints tend to have smeared water marks “bleeding” from the edge of my prints(8x10) toward the outside when it dry. I used B/S platinotype paper.
    Has anyone seen this or run into this problem? What causes the problem and how do you get rid of it? Thanks for your help.Tri Tran

    This is a common problem wih platinotype. The best solution is to use a different paper. I have never found a fully reliable way to prevent this from happening. Thorough clearing and a long wash seem to be important factors, but even then, this paper will still bleed loose metal occasionally. You really notice it when you have masked borders. COT 320 is the best fix, with the added benefit that you prints will look better at the same time.
    I just want to feel nostalgic like I used to.

    I have also seen it happen with Bergger COT 320 on occasion. I have no idea what caused it then. I have been working with Arches Platine for a little while.

    Interesting. I have never had it happen with COT. Always a gremlin lurking around!

    I have some negs that I might try with COT because they aren't working out well on Arches Platine. Hope it doesn't happen again. Maybe it was the conditions I was printing in at the time (less than ideal humidity and it was early February). Of course, I was making prints for our camera club show at the time. I got them made, but it took a couple of tries.

    Yep, have seen it with VDB and Ziatypes using Platinotype also. Figured it was just something I had done wrong. Since then have moved away from Platinotype and over to Arches Platine/COT320. Dang nice paper.

    I've had the bleeding issue with COT on occaision. Never with Platine, though. Platinotype is good for lining bird cages. :-P

    You might try image side down processing and clearing. This will require additional care in handling your prints and smooth bottom trays. I would also recommend that you try and rotate your prints in the print washer. If you are using a water rinse after your developer, you may also try going directly to your first clearing bath.

    Reducing your coating volume has also worked with some papers. Here you must check for good blacks and enough solution to prevent over working your coating solution.

    I've had this problem on and off for some time, especially with Platinotype but occasionally with Platine. I've had good success by letting the print drain for a few minutes (in the wash tray at an angle) after the final wash and then placing face up on a clean surface and drying with a hair dryer until the surface is free of surface water. Then I let it dry naturally overnight. This has pretty much cured this problem for me.

    I''ve heard others speak badly of Platinotype as well. I had a cheap source and got 50 sheets recently and haven't had any trouble. However, I have not had the chance to try the COT or Platine and have some of both on order. What kind of results should I expect as opposed to the Cranes?
