Laser Etching
The first example below shows the advantages obtained with Multicolored DPM and the Multi Acquisition Setting mode.
The second example shows codes produced using the laser etching process on metal surfaces that do not have evident
machining flaws, however, these examples are characterized by reflectance dependent on the direction of illumination.
