Coding with laser reactive ink on glass

laser-coding-macsa-perfum

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.

laser-coding-macsa-perfum-02The 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.

Laser marking on aluminum

 

 

There are many reasons why the products are coded, thanks to Macsa ID laser equipment, almost all substrates may be marked with guarantees of permanence and contrast.

This is the case of aluminum valves. A 2D Datamatrix code marking was performed on them to control traceability.

System to mark aluminum cans with 2D QR codes

 

 

 

 

 

In aluminium cans, the marking quality is extremely important because this code must be read by smartphone applications. The F-9050 UHS PULSED laser adapts to beverage high-speed production lines and guarantees high definition, contrast and the legibility of the code.
