Abstract

Each document (W1) is provided with a security feature in the form of a foil component (2) which is permanently attached to the document and cannot be changed without destroying it. Before the foil components are applied to the documents, they are provided with machine-readable image information which is variable from one foil component to another (3a, 4a). Once the foil component has been applied, the documents are passed through a reading device which reads the variable image information (3a, 4a) and controls a printer which applies a copy of this variable image information to the document outside the foil component. This can be in particular a combination of characters (7a) which is printed as part of a serial number (6a).

Claims

1. Process for the production of documents (W1, W2) with a security feature in the form of a foil component (2), which is permanently attached to the document and cannot be changed without being destroyed, characterised by the following steps:

giving the foil component (2) visible machine-readable image information which varies from one foil component to another (3a, 4a;

3b, 4b) and a non-variable image section (5), applying said foil component (2) to the document (W1, W2) passing the documents (W1, W2) through a reading device once the foil component (2) has been applied, and applying via a printer controlled by said reading device a copy (7a, 7b;

8a, 8b) of said visible variable image information to the document outside the foil component (2).

2. Document according to claim 1, characterised by the fact that the variable image information contains a combination of characters (3a, 3b), in particular a sequence of letters and/or figures.

3. Document according to claim 2, characterised by the fact that the combination of characters read (3a, 3b) is applied as part of a serial number (6a, 6b) to the document, preferably a note of value.

4. Document according to claim 1, characterised by the fact that the variable image information also contains a figure (4a, 4b).

5. Process according to claim 1, characterised by the fact that said copy (7a, 7b;

8a, 8b) of the variable image information is applied to the same or to a different scale.

6. Process according to claim 1, characterised by the fact that the printer used is a non-impact printer, such as an inkjet printer.

7. Document with a security feature in the form of a foil component (2) which is permanently attached to the document and cannot be changed without being destroyed, characterised by the fact that the foil component (2) comprises visible machine-readable image information (3a, 4a;

3b, 4b) which is variable from one document to another (W1, W2) and also a non-variable image section (5) and that said variable image information is printed on the document again outside the foil component (2), this being in the form of a copy (7a, 8a;

7b, 8b) to the same or to a different scale.

8. Document according to claim 7, characterised by the fact that said non-variable image section is in the form of a hologram.
