That was the contention of the two companies which preferred gold 
sputtering of the wax masters, Edison and Western Electric/World 
Broadcasting System.  But finely powdered graphite has the consistancy 
of talcum powder, so it really might not make that much difference.  It 
is a factor only in wax mastering, not lacquer,
