Alumamark - Introduction

PROCESS

Make your mark with a Co2 laser on Alumamark.

Alumamark is a specially treated anodized aluminium sheet that changes colour when contacted with the energy of a Co2 laser. Consistent, one-step marking, without chemicals or fill. The Co2 laser creates the image within the anodized layer, resulting in smooth-surface graphics with exceptional resolution.
