European patent for laser marking technique

A European patent has been granted to DataLase for the new pigment that forms the basis of the company's laser marking products for primary and secondary packaging " the Packmark and Casemark flexo and tape.

The DataLase process features the patented pigment, which undergoes a colour change reaction from white to black to form a positive image once exposed to a computer-controlled low-power CO2 laser.

The process requires no inks, ribbons or other consumables, making it simpler, cheaper and more environmentally friendly than traditional printing techniques.

The laser-based print engine is efficient, with almost 100% production uptime. The lifetime of the laser is over 30,000 hours and, compared to thermal printers, it requires little maintenance and no replacing of print heads due to wear and tear.

Steve Kelly, CEO of DataLase, said: "The significance of the DataLase process has been recognised with this patent. We will continue to expand on our extensive patent application program with the aim to further establish our unique approach in applying colour change know-how to solve practical manufacturing problems."
