The targeted removal of layers of material or roughening of the surface is known as engraving. A contrast to the rest of the surface is created by changing the texture of specific areas.
Almost all materials can be engraved provided the right type of laser technology is used. A range of different effects can be created on the various different materials. The engraving depth and surface quality can be defined extremely accurately with the right laser parameters.
Unlike marking by annealing, laser engraving is not sensitive to increases in the temperature of the material and is therefore extremely secure. An engraved mark can only be removed by cutting it out of the material.
