Joe - I have some hot-foil printing process rolls - metal film on plastic backing made to produce metallic writing in cards by stamping with a hot stamp with raised area to transfer metal to card etc. That MAY be able to be used in some way. Do you wear eye protection? Might increased dwell time and some means of improving insulation improve the result. PCB photo etching sounds useful. Maybe you can use materials which are not suited to normal photo processes.
