Engraving is a mechanical removal of shavings of material such as glass, wood, synthetic, metal or ceramic.

The engraving done in the manufacture of signs is achieved with a rotating burin machine, whereby material is removed mechanically from the surface. Colours are applied in the hollowed out areas. The hollowed out areas are larger than in etching (chemical engraving).

By using computerised engraving machines various vectorised data file formats can be used. The vector data permit a replication of the motive to be engraved without losses, something not achievable by manual engraving.

A modern method of engraving is the laser engraving. In this method the material is heated so extremely by the laser beam that it is thermally changed, causing a contrast and it is burnt or vaporised.

Engraving is suited for large series only when a greater depth of the hollowed out section is required than can be achieved by etching.

The typography displays traces of the rotating burin. In the etching process a more even, fine-corned hollowed out area results.
