Laser marking a barcode

Achieve better readability of barcodes and text on metals

This page will show you methods of laser marking barcodes and text on metal. Achieve detailed and readable marking results on even highly reflective materials.


Different methods of laser marking metals

Laser markings on bare metal can often be difficult to read. Depending on the surface and exposure to light, the markings may reflect strongly, making them difficult for people or optical readers to read. In our example, we show you how different a laser marked barcode on metal can appear in different exposures to light.

Better readability with "cleaning function"

By using the cleaning function, the laser automatically creates a matt finish in quiet zones (non-marked zones) after engraving. This process not only roughens and consequently brightens the area around the marking, but also cleans the edges of the engraved areas. This results in a reflection-free marking that does not need to be cleaned. The cleaning function can be found within SpeedMark in the parameter "filling" with a single mouse click.
