Low energy marking with C02 laser The laser beam moves over the applied Ciba® PERGAMARK™ coating like a pen, generating the marking information via color change. This process (referred to as stroke marking) is computer controlled, which allows for flexible labelling options. Learn more about laser basics

Laser (Light Amplicfication by Stimulated Emission of Radiation)
Ciba® PERGAMARK™ is optimized for CO2 lasers which provide serveral benefits.

• Low purchasing costs
• Low power laser
• Low running costs in use with PERGAMARK™
• Virtually zero maintenance (runs for 1000s of hours)
• Safer wavelength compared to UV lasers

Electromagnetic Spectrum
The wavelength of the CO2 laser is located in the far Infrared of the electromagnetic spectrum. The laser initiates a thermal color change reaction at the specific wavelength of 10'600 nm.
