Re: Satista question

Yes Loris,

After development you need to wash the print with running water before clearing and sometimes, according tp the water pH you get different color result.
If you don't wash carefully you may have some bleeding.

OK, I just made my first try:

10 drops AFO + 1 drop Li2[PdCl4] with 4% AgNO3 developer on Weston Paper.

1. I guess thin papers like Weston aren't suitable for this process; they become wavy and this even development difficult.

2. Quite a lot printout (but not complete); probably because I used a lot of Pd..

3. This paper definitely doesn't like a second development pass - it bleeds incredibly in the second past.

Philippe, not I understand the point in your warning: one should be careful in both development and first wash -> because of possible bleeding problems.

4. Development was uneven.

5. I like the color and Dmax with the above stated coating solution.

6. It's a messy process.


1. Use thick, dimensionally stable papers.

2. Do the development in just one pass and do it as slow as you can. (That is for even development with good Dmax)

Will share more information as soon as I have time to make another experiment.

Best regards,

Thanks Philippe. But, to what should I pay attention? I plan to use 2%
Citric Acid as wash water before toning - that's what I do with my POP
Pd, Vandyke and Argyrotype prints...

You need some pd or pt to get image but you can go down to 1 drop pt ot
pd for a 8x10 print. First washing after development is very treacky, be
very carefull.

Thanks Marek. I'll have to use Pd then, since I have very little (>10ml) Pt solution. If 1 drop of Li2[PdCl4] per 25-30 drops of 20% AFO

is enough for a print with good Dmax that's fine for me... (I don't care much about the color right now -> will tone the image with Gold/Thiourea

What are the effects of playing with solution strenghts? For instance, can I use 40% AFO for faster printing times? Should I also change the 4% AgNO3 solution strength accordingly? Will using a stronger sensitizer give me better/stronger Dmax? How is Satista Dmax compared to POP (or
DOP) Palladium prints? What can you say about the characteristic curve
of the paper? I guess it will need digital negatives with less drastic
curves adjustment -> due to lack of print-out...

Thanks again,

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. Marek

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,
