The production process is for a document having a carrier layer (20) and a covering layer (26) Some regions (34) are free of coating. A laser wavelength it identified to bring in the coated regions. The carrier layer with opposite first and second (24) main surfaces is prepared. The absorbent covering layer (26) is applied, followed by a mask (28) defining the coating-free regions. Laser radiation is then applied. |
