RE: Ware/Malde-Ziatype-DOP palladium,was RE: "New" Paper for Pt/Pd (and other iron processes, too)
I wasn't making it up! From Dick Sullivan's article, The Ziatype Compared to the Ware-Malde Process found at http://www.bostick-sullivan.com/techart.php: "The lithium salt, unlike the rest tended to produce an almost blue black image throughout a wide humidity range. Originally I was not particularly looking for a POP process, but the apparent hygroscopicity of this material pointed me in that direction. My thoughts on this were that if I could find a corresponding "brown" producing component that could be mixed with the lithium palladium salt, we might have a system for POP printing that was largely independent of humidity." Am I completely reading this wrong, or does this say that ziatype isn't as humidity-dependent as other palladium processes?
