Cermak help...not taking to metal

I ha e a ton of metal bracelets that need to be finished and am struggling with Cermak. 80 watt ruida, lightburn software… My text won’t stay and is looking Chinese. Parameters of bracelet are…0.5x1.6. I did 30% speed, 100% power…
Sprayed, dried and words still come off… Any suggestions?

What metal type? What steps did you do to prep the metal first?

You are going to need more power and lower speed. I’d try 50% per and 75 speed

It’s like a anodized aluminum… Uncoated, cleaned with alcohol.

We actually went with galvanized spray paint because we ran out of Ceremark and it worked great.

Post up some pictures please.
