FIELD: printing industry.
SUBSTANCE: invention relates to a method of manufacturing a protection property for the protective element, counterfeit-proof paper or data medium. The method of manufacturing a protection property for the protective element comprising a substrate which has at least one through hole and at least one marking in accurate register with this hole. The substrate, at least in the area of the manufactured marking is equipped with a marking substance modifiable by laser. During the same technological operation by exposure of laser radiation at high laser power at least one through hole is made in the substrate. By exposure of laser radiation at lower laser power at the marking area the marking substance is modified and thus at least one marking is created in accurate register with the through hole.
EFFECT: proposed protection property enhances the counterfeit protection level of the protective element.
