Abstract

According to one example, there is provided a visual security feature. The visual security feature comprises a security feature printed on a media. The security feature includes a security code printed on the media, and a holographic image is embossed on the printed security feature.

Claims

1. A visual security feature comprising:

a media;

a security feature formed on the media, the security feature comprising a field of printed ink surrounding a security code, the security code defined by an absence of the printed ink inside the field; and

a holographic image embossed in printed ink of the field of the printed security feature.

2. The visual security feature of claim 1, wherein the printed ink of the security feature comprises dried electro-photographic ink, and wherein the holographic image is embossed directly on the printed ink.

3. The visual security feature of claim 1, wherein the security feature includes a unique or substantially unique security code printed in a text size of 1 point or less.

4. The visual security feature of claim 1, wherein the security feature includes a unique or substantially unique security code.

5. The visual security feature of claim 1, wherein the field is a rectangular field centered on the security code.

6. The visual security feature of claim 1, wherein the field is a rectangular frame surrounding and enclosing a rectangular area.

7. The visual security feature of claim 1, wherein the security code comprises a bar code.

8. A system for generating visual security features comprising:

a printing module comprising a rotatable photo imaging plate, a laser imaging unit and a developer;

a controller to control the printing module to form a security feature on a media, the security feature comprising a field of material patterned and formed by the printing module, the security feature surrounding a security code formed on the media, the security code defined by an absence of the printed material inside the field;

a holographic imaging module for embossing a holographic image in the printed material of the field.

9. The system of claim 8, wherein the security feature comprises a unique or substantially unique security code in a text size of 1 point or less.

10. The system of claim 8, wherein the controller is to operate the printing module to form the security feature comprising the field centered on a unique or substantially unique security code.

11. The system of claim 8, wherein the printing module is to form the security feature using a thermo-plastic ink on which a holographic image is directly hot embossable.

12. The system of claim 8, wherein the controller is to operate the printing module to print a series of security features, each security feature comprising a unique security code.

13. The system of claim 8, comprising a media path through which a media on which is printed a security feature is fed to the holographic imaging module.

14. The system of claim 8, wherein the printing module prints security features on a series of adhesive labels, each security feature being unique.

15. A method of generating a visual security feature on a media comprising:

with a printing system having a media path, printing a security feature using a thermoplastic ink on a media in the media path; and

hot embossing the ink of the security feature to form a holographic image in the thermoplastic ink.

16. The method of claim 15, wherein the holographic image is formed in and over a field of printed material comprising the ink so as to surround and be readily visible around a security code contained within the field of printed material.

17. The method of claim 15, the security code comprising both a text string and a machine-readable barcode, the security code defined by an absence of the printed material inside the field.

18. The method of claim 15, further comprising:

heating the ink of the printed security feature to above a softening point; and

embossing a holographic image on the heated ink of the printed security feature with a holographic master stamp or roller.

19. The method of claim 15, further comprising:

generating a series of printed security features on the media, each having a unique security code; and

embossing a holographic image on each of the printed security features.

20. The method of claim 15, wherein the holographic image is embossed directly on the thermoplastic ink.
