Processes Color Removal / Material Removal

Color Removal / Material Removal

Marking by removing color and material is used especially in coated materials and anodized aluminum as well as in fittings, packaging materials and labels. The existing color, coating and surface layers are partially removed and the base material becomes visible.

The layers to be removed absorb the laser light, the material heats up and vaporizes at relevant places. Since the surface layer and protruding base material have different colors or the base material is often also back-lit, the marking becomes clear and visible. 

Since the final markings are very rich in contrast, this laser marking procedure is mainly used in the automobile industry for the day/night design, in the marking of the most varied control elements and keyboards as well as in the packaging industry. 

Suitable laser systems:

• Fiber laser marker
• Laser marker for Day-Night-Design (color removal)
• CO2 laser marker
