Laser Marking Systems / Laser Markers
Laser labeling is the process of using a laser marking machine to put a label on a product. The label can be used for traceability, identification, or adding regulatory information. Replacing a labeler with a laser can have benefits across many aspects of production.
Using a laser marking machine rather than a standard inkjet printer for labeling will improve value with time, money, and production. Laser markers decrease production time, increase permanency of labels, and decrease use of extra materials.
Below, we will discuss the differences between laser marking and standard labeling, the characteristics of each, and the best machines to use.
Labeling and Laser Marking Characteristics
Laser markers operate differently than standard labeling systems. Ink labeling systems need extra materials to minimise damage to the product and get an intense mark. These extra materials are usually ink ribbons or thermal heads. Because of the precision of a laser, labeling with a laser marker only requires a UV laser machine.
UV lasers work by passing a standard wavelength through two crystals, which creates a thin laser with high absorption. The high absorption is not synonymous with high heat, a UV laser is gentle on materials and can independently mark without needing protective materials. Because of the high absorption rate, the marks are permanent and do not fade over time.
Inkjet labeling machines were standard, but new laser marking technology outperforms these machines.
