Patent ID: 8141970

Claim:
A method of decorating an uneven surface of an object which is dimensionally stable by a printing operation, wherein the object to be decorated and a digitally and contactlessly operating printing head are moved relative to each other during the printing operation and the printing head is actuated by a control device for dispensing ink, comprising the steps: creating a control program for controlling the printing head in dependence on the height profile of the uneven surface to be decorated of the object; detecting the relative position of the surface to be decorated of the object relative to the printing head; actuating the digital printing head with the created control program; and wherein prior to the decoration operation a desired ink layer thickness is established in dependence on the location of the uneven surface to be decorated of the object and the control program is created in dependence on the predetermined height profile of the surface to be decorated and the desired ink layer thickness, wherein the digital printing head is controlled with the created control program in response to the topography of the uneven surface to be decorated to produce the predetermined desired ink layer thickness in dependence on the location on the surface to be decorated of the object.
