The outline of the design or layout is followed by the laser beam, this does not cut through the material but scores the surface.

This process is mostly used in two ways :

To mark parts where the need is to produce a serial or part number to a product in the most cost effective way.

To highlight engraved areas of a design or layout on wood, paper and card particularly where there is a lot of detail to a design that needs to have more contrast to the rest of the engraving.
