    Yes, this sounds promising. Perhaps instead of etching w/ acid, this step could be replaced by electroplating.

    Would this theoretically work?

    and about the plating: can one achieve greys (not-white, not-black) with this? except when using a printing screen (or is it grid?? sorry don't know the english word for the little dots).
    Mr. PP,

    Don't be so quick to jump. Gum can be printed on glass and metal!

    see my next post. it probably can, but without sizing/ subcoats? i doubt that.

    But you didn't say that to begin with did you?

    Anyway with the proper substrate applied to glass, metal or wood gum layers can be printed.

    OK, so I've had some recent thoughts on this.

    Another alternative method for "metal prints" would be to use steel bluing, like in guns. I think the best way to do this would be too make a pigmentless carbon transfer to a polished piece of metal (just like a Woodburytype) and then apply whatever method to tint the uncovered areas, whether it be electro-plating, patina, bluing, rust, and so on.

    Different metals and different treatments could produce a wide range of looks.

    From 1899, British Journal of Photography, Vol. 46, pg. 411:

    METALLIC PHOTOGRAPHS:

    It is about two years since we referred to the charming method of photographic printing which the Metallic Photo Printing Syndicate, of New Southgate, was formed to work and exploit. The results could not fail to excite admiration. The image, in brilliant pulverulent silver or gold, is transfered to a surface of polished mahogany, previously made black, and is subsequently treated and varnished in such a manner that the destructive agency of the most powerful acids has no effect on the picture, which may therefore be looked upon as possessing the elements of permanency in the highest degree.

    The process since its first introduction has been considerably improved in its working details by Mr. F. Ahrle, the managing director of the Company, and the latest specimens shown us possess a depth and richness of image which could scarcely be improved upon. Besides portraits, the process is well adapted for the reproduction of pictures, advertising plaques (sheets of ferrotype here constituting the support), and other purposes. Mr. Ahrle tells us that, given suitable negatives, the best possible results are easily and inexpensively produced at his works.

    Nothing could have a richer decorative effect in the house than a large portrait or reproduction of a picture with the image in bright silver or gold on a massive, highly polished ebony black support. Besides the element of permanence, these pictures have every good photographic quality, detail and gradation, light and shadow being perfectly rendered. We urderatand that these metallic photographs (in which the only fault we can find is their awkward name) are shortly to be brought very prominently to the notice of the public.


    I'm not sure if that last line ever came true... but I'd love to see one.

    Chris ,

    I had been posted a thread about electroplating silver print with platin or titanium 1 or 2 years ago.
