Peter,

Matte board takes a gold foil image very well. The process isn't very involved:

1) Create a die from camera-ready artwork. The dies are usually made from magnesium, using an acid etching process. Usually, professionally done (outsourced).

2) Attach the die to the heat platen of a hot stamping machine. Heat to approx. 200 degrees. Gold generally needs less heat than other colors.

3) Place matte board in position.

4) Place gold foil between the die and the matte board, either by placing a roll of foil in an auto-advance mechanism, or by manually placing a piece on the matte board.

5) Print, by pulling the handle or pressing the footswitch of a pneumatically-operated machine.
