I think your best bet would be to use a process like one of the
letraset plastic-laser bonding processes to get your gold tone. If you
are printing with a laser printer (even color), you can output the
gold layer artwork first, then melt opaque metallic gold toner into
the black, covering it over, and then run it back through your printer
for the other layers. I can't remember the name of the process (there
are at least three or four in the market in the U.S.), in French or
English, which does it, and you have your choice of a spectrum of 100
Pantone tints, including shiny metallic gold, silver, copper, green,
purple, red, blue, and matte gold, silver ('aluminum'), and a few
other metallics. They work spectacularly well - it really does look
like gold-embossing. If all you are making is a maquette, then this is
perfect. If you want production, you have to print with gold ink,
period, the effect production is too expensive and tiresome to do. If
you want 'gold' look then balance to a pantone gold, choose where you
want a pseudo-highlight to be, and do a fountain fill to from 50/50
tint/black to 100% white at that point, then fill back to 50/50
goldtint/black. It won't look like gold, but like 'metallic yellow'.
