    Cyanotype over pt/pd

    Hello All, Was hoping for some help on this. I've made some cyanotype over pt/pd prints this evening and have run into yellow highlight staining. The paper isn't washing back to white in the highlights. This is unlike what happened with a straight cyanotype test, which cleared back to paper white. What could be the cause of this? Is there a remedy or any way of avoiding this in future?

    Cheers,
    Gareth

    I've never done cyanotype over pt/pd before. I'd like to see what it looks like... My first thought is maybe there's a reaction between what is left from the pd/pt printing and the cyanotype chemicals. Looking up some old threads, it looks like there could be some reaction. But FAC is really soluble in water, so I don't know what it would stick to the paper like that. Is it completely staining and not washing out at all? (I'm looking at this: http://www.apug.org/forums/forum42/4...palladium.html which may or may not help out all that much)
