I tried omitting platinum form the formula for satista prints and it did not work. No image was formed with exposure times similar to what I have worked for satista process. I do not have my notes handy at the moment, but I can check later of what noble metals I have tried. I vaguely remember tryig palladium and gold as a noble metal sensitizer for the process. Platinum works the best and that is what I mostly use.
I'll get back to you later on this.

Hi all, I have a question for Satista printers (Marek M? Philippe A? ...?):
I want to try Satista prints for sake of economy -> I have little Pt and Pd on hands (which I can't obtain in Istanbul - have to import; I real PIA with current customs regulations) but I can buy AgNO3 and K[AuCl4] locally - at very low cost... Question is: Do I strictly need any Pt or Pd salt for making Satista prints (I guess they fuction as catalysts rather than image-forming substances)? Can I make good Satista prints w/o using any noble metal salt, by just using Ammonium Iron(III) Oxalate as sensitizer and AgNO3 as developer?
Thanks in advance,
