Laser marking equipment can be categorized into etching and dot matrix types based on their marking forms. Most laser marking devices in the market are etching types, whereas Marken's laser marking equipment utilizes a novel dot matrix technology — dot matrix retention technology. Line-type laser machines etch out the complete path of the characters to be marked, while dot matrix laser machines only etch out some important trajectory points of the characters. Consequently, in the same energy condition, the new dot matrix laser marking machine prints faster.
