With the help of an intensive laser beam, objects can be labelled or marked. In contrast to laser printing, where a weak laser beam controls only the pigment application on the printed material, laser marking changes the inscribed material itself.
The process and the associated energy input depend on the material. Laser markings are water and smudge-proof and very durable. They can be generated quickly, automatically and individually, which is why the process is often used for numbering prototypes.
It is also possible to apply very small machine-readable markings directly to objects.
