The Malde-Ware method, otherwise known as Print-Out Platinum-Palladium Printing, or the Ammonium Print-out was invented in the 1980s by Pradip Malde and Dr. Mike Ware. Their method related to the original ‘print-out’ platinum process of Giuseppe Pizzighelli from 1887, employs a better-behaved iron sensitizer. Ammonium ferric oxalate is substituted for the notoriously unstable ferric oxalate. Further, ammonium salts of platinum and palladium are used rather than potassium salts yielding a higher degree of chemical solubility while also producing more hydroscopic surface when applied. The concentration of noble metals is much higher in Malde-Ware than competing Pt/Pd methods allowing for less solution to be applied to the paper, yet producing higher dMax, better acuity, and smoother tonality.
You get a bottle containing 100ml of Malde-Ware Methodology 1a Sensitizer pre-mixed 1;1 with a 50/50 ratio of Platinum/Palladium.
This chemistry is compatible with Malde-Ware Printing Out Process platinum and palladium printing. It is reagent quality of exceptional purity.
