Laser marking machines can not print color.
Laser marking is the use of a laser beam to mark permanent surfaces on a variety of different materials. The effect of marking is to expose deep substances by evaporation of surface substances, or to "engraving" traces by chemical or physical changes of surface substances caused by light energy, or to burn off some substances by light energy to show the desired etching. Pattern, text. So the printed content is monochrome, not colored.
However, if a color laser marking machine is used, a color pattern can be printed at one time. However, because the technology is not very mature or has suffered a lot of limitations, it is also unacceptable to most manufacturers in terms of price. Because a color laser marking machine can buy several laser marking machines.
