Very few papers are much good for pure platinum prints. I use Herschel and Buxton, but I'm wondering if there are more out there. I know that there are plenty that work for palladium prints (with or without acid preparation) - COT320, Platine, et cetera. What I'm interested in is papers that work well if you have no palladium in your coating - i.e. when you use just ferric Oxalate and Potassium Chloroplatinite.

Thanks in advance,
Ian.
