Craig Smith asks is there any inexpensive way to restore graphics on
metal discs.  Both he and I are veterans of Xerox Corporation, having
worked together on a few projects.

As I recall one can put together a graphic in a mirror image on a piece
of 11" x 17" paper, in black and white or color or a combination of
both.  Once the image is acceptable it can be transferred by heat to
the disc.  This technique is used with special toners to make gold and
silver plaques, which I use often.
