You'd get a better result using a laser.
I thought of that, but I also figured that the conical nature of the
hole left behind from a bit would catch the light better than a
roughened surface etched by a laser. I do have access to a laser
cutter, but I pay an hourly fee to use it. Rastering several square
inches costs me more than lunch money. It's cheap to cut things out
with vector cuts, but rastering (for letters, logos, etc) can easily
double the bill because of the number of passes it takes to sweep over
the area.
I had one project recently where the cut time was 3 minutes, but the
text on the item took 7 additional minutes.
