I dont see a contradiction with this Sandy. Youve described how the image forms at a deeper level of detail than I did. For the lay public its enough to say that image is formed from the noble metal. For people who want to know more, theres a chemical process involved as youve described.
I was trying to find a form of words that meant that using platinum is a requirement to it being called a platinum print, while other metals are an additive. Personally I wouldnt consider a pure palladium print to be a platinum print with or without trace amounts of platinum. I think it would also be stretching things to call an extreme Pt

d ratio such as 1:11 a platinum print but Id rather leave it to peoples conscience than try to dictate a purity standard.
Perhaps this would be a better first sentence: A platinum print is a print made using one of several processes which uses platinum to form an image under ultraviolet light.
My instinctive answer is that platinum toned kallitypes is a more appropriate label. Im no expert on kallitypes (so would bow to your and others judgement), but if theres a fundamentally different process then to label them platinum prints would seem like an attempt to deceive.
As I said earlier in the thread, there should never be an attempt to deceive. The important thing is that our communication is pitched at the right level for the audience. That means balancing the need for full disclosure with the need to be understood and its more important to be understood than it is to reveal all the technical details.
Its the nature of our society that the rarity (and price) of raw materials is a significant influence on the market price charged for an artwork. People tend to pay more for a gold necklace than they do for a silver necklace, but in many ways silver is a more beautiful metal than gold. Similarly, in the past painters often used ultramarine (lapis lazuli) specifically because by doing so they demonstrated the wealth of their clients.
Perhaps some people do feel the need to label their palladium prints as platinum prints for this reason, although I havent seen this personally. This would sadden me because, although I dont particularly like the palladium aesthetic (thats just my taste not a value judgement), I would hope that people would call a palladium print a palladium print and allow the strength of their work to create the value.
