Over the last month I have been researching and testing the platinum printing technique used by master platinum printer Irving Penn. The process initially involves bonding the printing paper to aluminium, this enables the paper to maintain its dimensional stability and allow for successive multilayering of platinum/palladium chemicals. The process uses twice to three times the amount of platinum/palladium chemicals and takes at least double the time to create compared to that of a single layered platinum print.
After numerous tests and late nights i can now report the results. The singled layered scanned image shown below has a maximum density of 1.41 and the multilayerd is 1.58 , mimicking the initial test results reported previously (Click image to enlarge). To my eye the overall richness and three dimensionality of the multilayered print is significant enough to warrant further research. I intend on printing using this method in the future as for me it adds another tool to the toolbox in achieving the type of platinum prints I have always wanted to create. I will be testing with multilayering gum and cyanotype over platinum in the coming months and will post the results
