Judy:

    You might consider applying a very thin coating of silicone oil to
    the surface of a plate and then applying molten wax to the surface
    of the plate to make a positive replica of the plate. You could then
    make a lost wax casting of the wax replica in brass. The brass
    replica could be placed on the surface of annealed fine silver
    sheet, sandwiched between copper sheets and rolled through your
    rolling mill to reproduce the initial surface of the printing plate
    onto the fine silver. If you wish to have a positive image result on
    the fine silver, you'll have to make a wax replica from the brass
    casting and make a second casting from brass to use as the rolling
    plate. 

    You could also get a positive image from the pringting plate by just
    making the wax replica of the plate surface and casting this in fine
    silver, sterling silver or gold. 

    My recollection is that these engraved pringting plates were made
    from a zinc alloy or aluminum and are very soft. I do not believe
    that the printing plate itself is suitable for running through your
    rolling mill in order to transfer the image to another metal. 

Good luck;
Howard Siegel.
