Type 4 – “White” or “Frosted” Etch


Also sometimes referred to as Laser Etch or Laser Engrave

This type of marking is particularly useful on highly polished or reflective parts, or on metals having a dark coating. The laser lightly disrupts the surface of the component, ablating any coating and leaving a mark that appears white or “frosted”. This type of mark is also used on pewter or silver, since it does not require wiping (which can scratch or scuff soft metals).
