This marking technique uses a laser light beam with a fibre optic medium, focused on a surface. This surface is "burned," so the desired image (previously sent from a computer) is marked.
Laser's main feature is the mark's durability. It cannot be removed, since it penetrates and wears down the material. The mark takes on the colour of the bottom of the material, since this technique does not use ink.
The result of this technique is top definition of the image engraved on the medium. It has several applications, since it can mark almost any kind of material: for example, wood, metal, rubber, PVC or fabric.
