Hi everyone!
I recently decided I wanted to do some art projects and decided on Palladium Prints. However I found it very difficult to find information on how to produce the best possible black and white digital negatives to do these Palladium prints, as a photoshop girl you can imagine I am a bit of a control freak and want to be able to reproduce in the final print what I see on the screen, that is the same ammount of contrast, gradients and dynamic range. Hopefully someone can point me in the right direction.

Hi Aurore,
The other replies that mention the HP 3200 process are on the right track. HP used to have a .pdf available on how to do it. Here's a quote someone posted from the HP info: “The process described here was performed with the goal of creating feasible negatives for monochrome and color alternative process such as platinum/palladium, carbon, cyanotype, gum, carbro, multicolor carbon, and tri-color gum” and then “From a technical point of view, what is inside this preset is a green ink separation that has been linearized in terms of ultraviolet light opacity. The advantage of having this linearization is that when printing a linear ramp of green ink values with this paper preset, the result will be a negative with a near-linear response in any alternative process based on UV light. In certain cases, some calibration may provide additional improvements. However, the tools needed to perform this calibration are part of the standard printer software and hardware."

http://www.dimagemaker.com/2010/08/14/hp-supports-platinum-printing-and-other-alternative-processes/As you can see, the trick is to get an inkjet transparency that lets UV (not visible light) through in a linear way. As the other articles referred to by posters indicate, this is quite a challenge because you can't tell by looking at the transparency as you can for standard silver printing.
I've looked around for the original info from HP but the links just go to a general page on the HP site so they may not have it up anymore. Whatever you do, you're going to either need to get an HP3200 and the preset they created (which I recall reading worked extremely well) or you're going to have to duplicate the work that Moyo did using another printer and inkset.
To be contrarian, I went to a show at MOMA several years ago and they had side by side comparisons of 2 wonderful images taken on B&W negatives. There were 3 prints of each, a silver halide one, an inkjet one and a platinum one. To my amazement, here was no obvious "magic" to the platinum print. They all looked good, probably because they began with a technically excellent negative and were printed by someone who knew what they were doing. I will be so bold as to suggest that you invest the same amount of time, focus and energy in becoming a master of digital imaging and printing as you would to master the platinum process. If you spend that many hours/days/weeks learning to control tonality in the digital environment, you will get the look you want.
