Graduations can be done on metal surfaces by means of engraving where specific depth is required along with accuracy and durability. Engraved markings are usually preferable where final surface coatings such as paints and inks need to be filled in the depth for a good visibility.

The engraved lines with the numbers representing the dimensions in required units, in a desired consistency are the usual form of marking on a scale or a graduated collar. Sometimes high-precision graduations are directly engraved in plastic molding dies, by which the required markings will be directly impregnated on the surface of the plastic.
Graduation marking application is widely used in many applications like:
