Abstract:
A method for producing a coated and printed glass panel, includes a) providing a glass substrate having a metal-containing coating on a first surface and a polymeric protective layer with a thickness d arranged on this metal-containing coating, b) removing the polymeric protective layer in a first region using a carbon dioxide laser, c) removing the metal-containing coating within the first region only in a second region using a solid-state laser such that an edge region is created, in which the metal-containing coating is intact and in which the polymeric protective layer was removed in step b), d) applying a ceramic ink only in the first region, e) heat treating the glass panel at >600° C., wherein the polymeric protective layer is removed on the entire first surface, in the edge region, the metal-containing coating is dissolved by the ceramic ink lying above it, and the ceramic ink is fired.
