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 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, the material printed by the printing module, the security feature surrounding a security code formed on the media, the security code defined by an absence of the material printed inside the field by the printing module;

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

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

3. The system of claim 1, wherein the controller is to operate the printing module to form the security feature comprising the field centered on a unique security code.

4. The system of claim 1, wherein the printing module is to form the security feature using a thermo-plastic ink on which a holographic image is directly hot embossable.

5. The system of claim 1, wherein the controller is to operate the printing module to print a series of security features, each security feature comprising a unique security code.

6. The system of claim 1, comprising a media path through which a media on which is printed a security feature is fed to the holographic imaging module.

7. The system of claim 1, wherein the printing module prints security features on a series of adhesive labels, each security feature being unique.

8. A method of generating a visual security feature on a media, the method comprising:

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

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

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.
