It's similar to Gold toning, you can use Platinum or Palladium, it was once common for early printing processes. I've a few formulae in early British Journal (Photographic) Almanacs and other books from the late 19th C.

Satista. It' s a developing out technic where you use very little salt (palladium or platinum) and your developer is some Ag Nitrate mixed with glycerin.
Some prints on my website

POP,Salt prints, Kalitypes, Albumen prints etc were all treated with Platinum or Palladium as well, They are also SilverPlatinum or Silver Palladium prints.

It was a very common technique.

Well, that makes sense then, but the terminology is still a bit misleading - it would make more sense (if the real answer was known) to say "Platinum-toned POP silver gelatin" or whatever. My guess from looking at the prints on display then would be that they were platinum-toned Kallitypes as I really couldn't tell the difference between them and the straight platinum prints on display.

A Platinum toned Kallitype will have very similar tonality & archival properties to a Platinum print, I thing Loris Medici goes down this route for some of his images.

Economically it's far cheaper to go down this route as far less Platinum salts are used.

I did a quick check of an 1890's BJP Almanac and there were a lot of Platinum toners listed, some by paper manufacturers, also a few companies were offering platinum prints by enlargement, which I'd guess would actually be fully toned bromide prints.

Well, I would agree with Philippe (a very competent Satista printer) that "Silver Platinum" sounds more like another term for "Satista" process, to my ears. (EDIT: In the context of Steiglitz prints that is...) See this article (by Marek Matusz) for further info.

Regards,
Loris.
