Method and device for marking value labels

The method according to one of the preceding claims,

• characterized in that
• the motif is a bar.

The method according to one of the preceding claims,

• characterized in that
• the motif is a wavy line.

The method according to one of the preceding claims,

• characterized in that
• the high-energy radiation is generated by a light source that generates a directed beam that is guided over the surface that is to be irradiated along a trajectory corresponding to the motif that is to be created.

The method according to one of the preceding claims,

• characterized in that
• the high-energy radiation is generated by a light source that generates a continuous beam.

The method according to one of the preceding claims,

• characterized in that
• the motif is repeated in a pattern, whereby the pattern is applied so densely that at least two motifs are applied at least partially onto the surface of the value label containing a luminescent substance.

The method according to one of the preceding claims,

• characterized in that
• the value label is applied onto a surface that does not contain any luminescent substance, and the entire surface is irradiated with high-energy electromagnetic waves at the time of the first use of the value label.

A device for marking a value label that is intended for one-time use and that has a surface containing a luminescent substance,

• characterized in that
• the device comprises a radiation unit with which the surface of the value label containing a luminescent substance can be irradiated with high-energy radiation that is capable of creating a motif of limited luminescence on the surface of the value label containing a luminescent substance.
