Metal laser marking is another method that involves the basic laser engraving process. During this process a special chemical marking compound is used. Surface depths cannot be achieved, the surface of the material is marked with permanent black marks. This process is mostly used for metal engraving but it also works well on other hard materials such as ceramic, marbles and stones.
You send us your artwork. Like laser engraving the marking process involves using filled vector fills and strokes or image files in 100% black. Best to make sure that none of the artwork is grey or any other colour for that matter.
We spray your material with the marking compound manufactured by the company Cermark. When the laser comes into contact with the compound it heats the engraved areas to a high temperature which fuses with the surface to turn them black.
The machine moves down over your drawing to mark your material. When the laser has finished, we wash the excess compound from the surface to reveal the metallic surface with the black marking! Magical!
