Subsurface security
C ommercial trials are expected to begin this year on a new subsurface non-aggressive laser engraving system that could provide a complete track and trace system, deterring counterfeiters of products such as those in the pharmaceutical and cosmetics sectors.
The NAGINELS consortium,- Non Aggressive Glass INternal Engraving Laser System - is a two-year international project that has been funded by the EU and is made up of six SMEs and two universities.
The laser system developed by the partners can subsurface engrave any transparent material, such as individual glass or plastic bottles that contain medicines or perfumes. It can engrave either a special 0.5 x 0.5mm, 16 x 16 data matrix, in less than one second and almost invisible to the eye, or alphanumeric characters where each one is only 3.5 microns in height. The characters are almost invisible but under certain lighting conditions they show up with a rainbow effect and can be read.
