Laser engraving is a specific technology using the laser ray for surface alterations mainly on metal, metal plated, or wooden items such as pens, mugs, thermos flasks, knives, etc. During the engraving, small surface layer of the material (layer’s depth can be as small as few hundredths of millimetres) evaporates. The coloration and contrast of the final inscription depends on the source material of the engraved item. On a stainless items, the inscriptions are less visible, more decent thanks to the coloration of the very close original colour of the item. Laser engraving offers impressive, precise and long-lasting inscriptions on promotional items.
