The invention relates to a method for printing on traffic signs, which comprises the following steps: a pattern (3) of a traffic sign to be produced, which pattern is available in digital form, is read in by means of a read-in device (2) and the pattern (3) transferred to a printer (1); a hot-embossing foil (11) which is coated with a hot-setting adhesive is imprinted with the read-in pattern (3) by means of the printer (1), preferably as a mirror-image; the imprinted hot-embossing foil (11) is transferred to a laminating device (4) by means of a film guide (6), after which the laminating device (4) is used to apply the imprinted hot-embossing foil (11) by heat lamination to a reflective film (51) which has preferably been applied by heat lamination to the front side (52) of a traffic sign blank (5). Heat lamination is preferably carried out using hot-embossing dies (41) or hot-embossing rolls (42), either in points or across a surface area.
