Abstract

Large area decorations of glazings, ceramic paint or the like on glass ceramic, glass, ceramic or similar meltable substrates, in particular on glass ceramic cooking plates, are applied by the new method by means of a laser beam which is widened linearly over the entire width of the area to be decorated, as it were in a zone melting method. The linear energy supply zone is advanced at a speed high enough for essentially only the decorating material to be melted on or burnt in but ensuring that the thermal conduction front does not move appreciably into the substrate material.
