Security Technologies

Semi-Covert Counterfeit Protection

Thermochromic and luminescent inks as well as microtexts represent only a selection from our portfolio of semi-covert security features.

Advantages of Semi-Covert Anti-Counterfeiting Features

  • Can be integrated inconspicuously into the label design
  • Verifiable without complex technical tools
  • Insiders (brand owners, customs, caregivers if necessary) can easily recognize counterfeits
  • Usually do not require special approval (no design change subject to notification)
  • Can be integrated into labels for all types of products

Professional anti-counterfeiting strategies combine different technologies (open, semi-covert, covert) for best possible security and verification by different audiences.

Thermochromic Inks

Thermochromic inks change from colored to transparent when a defined temperature range is exceeded. The effect is reversible. For example, a color print becomes transparent when rubbed, or invisible lettering only appears under cold conditions. Our latest generation thermochromic inks are BPA-free!

Luminescent Colors

Luminescent inks are transparent and only become visible and glow under UV light. Luminescent inks are available in different colors.

Microtexts

Microtexts can hardly be seen with the naked eye. Microtexts are easy to communicate and easy to check using a magnifying glass.
