Glass, one of the most widely used substrates in cosmetics and perfumes, is one of the materials in which laser marking is of excellent quality and which is also considered as one of the hardest. In addition to this, Macsa ID has developed a system that allows a QR code plus 2 lines of text to be marked on a base of laser reactive ink.
The reactive ink base generates a black label as a reaction to the heat which then allows a clear and quality contrast to be made. Thanks to a patented system, the permanence and durability of the reactive layer against scratches and/or external agents is guaranteed.
With this system, which achieves high marking speeds, the possibility arises of marking variable or promotional codes (QR codes to be read with a smartphone) on substrates (glass) that previously required a machine vision system in order to be read later on. Moreover, the IP54 protection of the system prevents the glass debris produced from the marking from entering the laser or damaging the lens.
