UniColor®:  Laser transfer marking on the glass surface


The patent-registered boraident laser marking technology UniColor® generates a vitreous layer of nanoparticles on the glass surface. For this process, an argentiferous donor medium will be brought in contact to the glass surface and during a laser-induced process a high-contrast marking gets created on the glass material.


Properties of the marking

The laser marking technology UniColor® allows the creation a marking with the following properties:  

The laser marking technology UniColor® allows the creation a marking with the following properties: 

  • chemical and physical resistant like the glass substrate itself
  • thermal resistant up to Tg
  • resistant against UV radiation
  • no detracting of the glass stability (no inserting of strains or cracks)
  • forgery-proof
  • restrained, aesthetic, machine readable coloring
