发明名称 SECURITY FEATURE AND METHOD FOR PRODUCING THE SAME
摘要 A method for manufacturing a security feature for a security element, a security paper or a data carrier that exhibits a substrate into which at least one through opening and at least one marking in registration with the through opening are to be introduced. The method includes the steps of providing a substrate with a laser-modifiable marking substance at least in the region of the marking to be produced and, in the same operation, introducing at least one through opening into the substrate by the action of laser radiation at higher laser power and modifying the laser-modifiable marking substance in the marking region by the action of laser radiation at a lower laser power to produce at least one marking in registration with the through opening.
