How do you engrvae on brass and make the lettering dark (filled in) and not just an outline?

I am trying to engrave on brass. The lettering needs to be filled in and dark but all I am getting is an outline. Any thoughts?

Good luck. Co2 lasers are pretty much for natural materials. Most metals reflect over 90% of the power and ‘sink’ the heat that’s generated away from the cut.

The only option I know is coatings like Laser Bond 100.

If you’ve got a dark outline you’re almost there. Some lettering can be ‘filled’ and you may be very close to a solution.

If you’d like to share some pictures or some more information you can drag and drop images into a reply.
