Laser Engraving
Engraving of pictures and text in plastic laminates or cards by means of a laser. In the laser engraving process the data are written by blackening (carbonising) laser-sensitive foils (PVC or sensitized PC). The depth of the laser effects can be deliberately targeted; the following technical variations are in use: nternal (layer-specific) engraving: blackening in underlying layers through transparent (non-laser-sensitive) cover foils, example Germany driving license (given name, date and place of issue, signature). Raised (tactile) engraving, example : Germany driving license (surname, date and place of birth, serial number, driving license categories).
