Laser inscription is a method in which the industrial signage is marked by modifying the substrate with the help of an intensive laser beam.
Three variants are available: In laser annealing, colour changes are produced in the material as a result of exposure to heat and oxygen. In laser engraving, a thin layer of the material surface is removed. The third variant uses targeted colour removal of paint layers or coloured anodized layers.
Laser inscription is mainly used for subsequent additions of variable information, such as sequential numbers or barcodes.
Properties and benefits
- Lasting legibility
- Economical production, even of small series
- Variable marking/inscription possible
As an alternative without colour, with matt-glossy contrast of base material.
