Platinum/palladium prints are individually make by hand coating the freshly mixed metallic salt solution onto watercolor paper. First, the metallic solutions are mixed in a small beaker or shot glass, typically 16 drops each of Ferric Oxalate and Sodium Chloropalladite to which is added a “few” drops of Sodium Platinum “Na2” and a drop of Tween, a spreading factor. The mixed solution, is rapidly poured onto the humidified paper and rapidly, but smoothly painted over the paper surface to receive the contact print. I use a watercolor brush, but it can also be done with glass push rod or other techniques. The UV sensitive coating is spread just beyond the dimensions of the negative. The UV light exposure followed by the developer cause the metals to precipitate into the paper leaving the image under the negative and a black irregular border between the negative edge and the end of the brush strokes. If the coating lies inside the negative edge, the image will end abruptly with brush stroke irregularity without the black. These vagaries in the edge lend the renown hand-crafted unique character to the prints. It is, of course, possible to simulate the signature platinum edge with making techniques in image processing software such as photoshop but only with a great deal of bother will each images edge be individually unique.
