In laser marking or laser engraving, an amplified beam of energised light is used to change a surface so that an image is created. The resultant laser etching is permanent and abrasion-proof. The process can be used to mark a wide range of materials including plastics, metals, glass, ceramics, cardboard, wood and much more. Laser marking can be used to print texts, numerals, images and Data Matrix codes. It can also be used to print individual and varying information from a database on products or packagings on a conveyor belt.
