Our laser systems for the production of security features

Scope of application

In general, security features can be incorporated into different materials and in a wide variety of ways. In addition to special substances that are already integrated into the basic materials (e.g. banknote paper), further security features can also be added in the subsequent production steps. The aim is for some features to be visible to the naked eye or simple aids such as UV lamps, while other features are deliberately to remain secret in order to prevent counterfeiting.

Laser technology can be used to create different security features in banknotes, passports, documents and certificates, admission tickets - but also in pharmaceutical packaging.

The possibilities here range from laser cutting for viewing windows, perforating serial numbers, laser structuring of surface features to marking in special inks using UV or fibre lasers.

Depending on the requirements for the security feature, these features can vary greatly in size and type; the counterfeit protection results, among other things, from the high precision of the laser technology in combination with further processing steps in production.

The technology

• Typical applications are:
  
  • Laser perforation of banknotes, for example the denomination.
  • Laser cutting of viewing windows and geometric shapes in banknotes and documents.
  • Perforation of passports and identity documents (passport perforation).
  • Laser marking / laser marking in combination with special inks
  • Special machines - to suit your requirements
• The integration typically takes place in
  
  • Systems for the production of banknote paper and security foils
