For manufacturing companies who use CO2 Laser coders to print alphanumeric or 2D codes onto their products, you will know that while lasers are highly efficient, there are several factors that you need to consider in order to code your products successfully. To help you better understand these factors, Domino is pleased to offer a sequel to their Laser Basics video series, this time focused on Wavelength, titled, Domino Laser Basics: Wavelength to Substrate Matching”. This video describes the importance of understanding the relationship between the wavelength of a laser and your substrates, taking the guess work out!

This video walks the viewer through various factors that may impact code quality, much of which is dependent on key factors such as the characteristics of the material being marked. In the first series video Domino focused on the Power of Concentration, and while it remains absolutely critical, it’s equally important to understand the role the wavelength plays in achieving good marking performance.

As per Jon Hall, Senior Product Marketing Manager for Laser at Domino North America, “The wavelength of the laser must be well aligned with the absorptive characteristics of the material being marked.” In other words, how the temperature is elevated to create the required contrast in the substrate itself. Each substrate has a “hot spot” which results in the perfect code, which can only be achieved at that point where high absorption meets a specific wavelength. Do you have confidence your laser solution is delivering the best code for your substrate(s)?

While the video itself offers some technical details, both Hall and Dr. Stefan Stadler, Team Lead at the Laser Academy for Domino, also offer basic analogies for the novice manufacturer just familiarizing themselves with laser printing. For example, showing 4 different substrates – PET, Cardboard, Plythylene and Polypropylene – and highlighting that each have their own hot and cold spots. The material used by manufacturers is critical in helping to assess where that hot spot resides.

At Domino we assure a rigorous sample process of our Laser technology on your packaging, bringing with it a more scientific and technological approach. Partnering with experts in laser coding and what it means for YOUR substrates needs to be a critical part of your application. Domino takes the guess work out of the equation and delivers the right solution for your application.

We make it our business to know yours. Because supplying the technology is no longer enough…you deserve to have the experience and support and training that will maximize your investment, resulting in long-term consistent, reliable and accurate codes. This support is the Domino Difference. We invite you to find out more.
