Platinum printing is based on the light sensitivity of ferric oxalate. Ferric oxalate is reduced to ferrous oxalate by UV-light. The ferrous oxalate then reacts with platinum(II) or palladium(II) reducing it to elemental platinum (or palladium), which builds up the image.
Platinum and Palladium Prints. A method for printing photographs in these precious metals was first patented in 1855 by William Willis, an Englishman. The permanence of silver based prints was suspect, and photographers wanted a process where the image was sure to last. Platinum is an ideal candidate, as it is very permanent.
The Platinum Printing Process. For people who collect photographs, platinum/palladium prints are known for their beauty, archival stability and unique, one-of-a-kind print statement. Made from the salts of platinum and palladium, these prints are also called “platinotypes” or “platinum” prints. Platinum and palladium are noble metals on ...
The procedure is appropriate to palladium or mixed platinum-palladium prints. In a pure platinum print the print-out is less vigorous, and special care is needed as follows. Printing in Pure 100% Platinum To achieve the best quality, the following are the cardinal points to observe: The choice of paper is critical.
Platinum/Palladium printing expert Kerik Kouklis gives us the low-down on his favorite papers for alternative process printing. Photographers who work with the historic, hand-made or otherwise alternative printing processes know that a good print requires a good paper.
Since about 1990, my printing processes of choice have been platinum/palladium (Pt/Pd), and Pt/Pd combined with gum bichromate. The Pt/Pd printing process was invented by William Willis in the 1870s and patented commercially in 1879. By the turn of the century, platinum prints were very popular, valued for their beauty and permanence.

stages to a finished print. This chapter gives you alternatives to traditional platinum/palladium chemistry and provides you with a simple sensitizer “drop chart” that is based on the type of negative you are working with, rather than the print you would like to make. I also provide the
I find it fascinating to hand craft an analog platinum print, ultimately seeing the latent image on the exposed paper pop out when I pour the developer over the image. One of the attractions of the platinum/palladium method of printing over a traditional darkroom is that the process isn’t sensitive to low levels of tungsten room light.
