    Let me first point out a small irritation I feel: whereas the term "Kallitype" is a generic name of an iron salt process, "Ziatype" is a commercial term, a trademark for a combination of methods of the print-out pd/pt process which were composed by Richard Sullivan with the help of others. I would prefer to speak of print-out palladium here instead of using a trademark.

    Second, print-out pd/pt needs quite low-contrast negatives, in fact, it works best with a negative which also prints well as a salt print. Kallitypes allow to print a far greater range of densities. Also, as Nze points out, with the respective toner they tend to be indistinguishable from pt/pd prints. The downside is rather long and delicate processing, with a nagging awareness that some silver which might compromise long-term stability might still be lurking somwhere in the print.

    Hi Lukas I am quite surprise. I need longer DR neragtive for my ziatype and albumen print than for traditional palladium and kalitype; I can easily print a 2.6DR negative in POP palladium process where with kalitype I better be on the DR2

    Yes, Nze, that's what I mean, too. Longer DR = low contrast. I'd even say that the best neg for print-out palladium without contrast agent is closer to 3.

    Oh god, yes, I just realize I somehow got a twist in my mind. print-out processes are low-contrast and need a high-contrastr neg, oc course. Sorry for this, and thanks for the correction.
