One of our customers recently came to us with a specific requirement: they wanted to have our Cryptoglyph technology on their products but did not trust their suppliers to do so. At the same time, their bottle filling lines were already equipped with laser marking technologies. We, therefore, decided to use the existing hardware to engrave the Cryptoglyph directly onto the plastic bottles. To achieve this result, we had obviously to make a series of adjustments. One was to decrease the laser power to a level such that the marking was then invisible but still instantly detectable by our dedicated smartphone app. This new development greatly extends the use case scenarios for the Cryptoglyph.
