Hi Cor,
thank you for your quick help! To give you a short overview of the scenario: I am new in the field of platinum/palladium printing. I did the first test with Arches Aquarell paper and -surprisingly - it was not too bad. But I have the feeling that the coating could be better with the use of a surfactant. As far as I am informed one can also expect an increase in Dmax (and a lot of problems as well). I asked our chemists ( I am working at the University Hospital of Vienna / Occup. Med. Dep) and they gave me Triton X-100 which they don´t need anymore. Unfortunately I am a physician which means that I don´t understand chemistry at all. So I appreciate your help very much and will start with NP20.
Do you apply a surfactant???
Best regards
Christian

.as mentioned before by me; take a look at NP40
