Abstract

Disclosed is a method for inscribing or marking surfaces (1), especially metal surfaces. In said method, the surface (1) that is to be inscribed or marked is coated with an absorption promoter (2) in a first step, whereupon a high-energy beam (4), e.g. a laser beam, which colors the surface (1) as a result of the interaction with the absorption promoter by means of a temperature increase, is applied to surface elements that re to be inscribed or colored.
