Invisible UV serialization of difficult surfaces

The application of fluorescent materials in stamps has a long history. Security stamp-pad inks are still widely used in passports or in taxation documents. The carrier is always paper in these applications.

For brand protection, quality control, and authentication purposes there is a need for secure marking of plastics in a fast and cost-efficient way. However, stamping of difficult, non-porous surfaces like Polyurethane or other plastics is surely a great challenge.

Luminochem’s team of scientists solved this problem and we have developed a solution to mark these challenging surfaces. Our philosophy is to supply tailor-made solutions so when our partners have different requests, we always provide the best-fit systems available.

Fields of application

• On almost any surface: paper, plastic (even on Polyurethane!), metal, wood, etc…
• Brand Protection
• Quality control
• Product protection via direct marking

Application technology

• Manual application, simple stamping process
• Industrial application is also possible
• Difficult–to–print surfaces can be marked (non-porous plastics)
• Invisible or colored UV fluorescent prints
• Authentication with a UV torch

Security features
