METHOD AND DEVICE FOR MARKING A LICENSE PLATE FOR A VEHICLE TWICE, AND LICENSE PLATE DESIGNED TO BE SUITABLE FOR MARKING TWICE

摘要

The invention relates to a license plate (2) for a vehicle, having a front face (3) with a first surface (6), a rear face (4) with a second surface (7), and a coating (5) with a third surface (8). The first surface (6) has a first degree of sensitivity, the second surface (7) has a second degree of sensitivity, and the third surface (8) has a third degree of sensitivity with respect to a laser beam (12). The first and the third degree of sensitivity is each greater than the second degree of sensitivity, and a lower intensity of the laser beam (12) is required for marking the first surface (6) and the third surface (8) using the laser beam (12) than for marking the second surface (7) using the laser beam (12).
