I could probably do them on my machine if I could find suitably sized 
carbide bits, which are both hard to find in those sizes, and expen$ive 
at over a twenty a copy.  But slowly I expect as the spindle speed is 
only 2500 rpm max for the micromill.  I think most machines for cutting 
pcb's will have 20,000 rpm and up spindles & liquid or forced air 
cooling.  I believe there is a convertor program that can take a 
png/gif/tiff image and make gcode to be fed to emc out of it, I've used a 
similar one to carve fawncy nameplates out of door kicker brass sheet 
myself.  That one takes a line of text, and a path to a truetype font 
plus a filename as the input arguments, and generates a gcode output file 
in 'filename'
