Method for generating a security feature for a value and / or security product and value and / or security product (inkjet printing)

摘要

The following method is proposed for creating a security feature 200, in particular an individualizing feature, for a valuable and / or security product 100: (a) providing a substrate 105 having surfaces 101; (b) providing at least one application element 210 having a front side 211 and a rear side 212; (c) Generating a layer of an adhesion promoter 220 on at least one of the surfaces 101 of the substrate 105 or on the back of the application element 210, so that the adhesion promoter 220 is only present in at least one adhesion region 230 delimited by one or more free areas 240 on the at least one surface 101 of the substrate 105 or on the back 212 of the application element 210, but not in the at least one free area 240; (c) Application of the respective application element 210 with its rear side 212 to the at least one surface 101 of the substrate 105 provided with the respective layer of the adhesion promoter 220 or application of the application element 210 with its rear side 212 having the adhesion promoter 220 to one of the surfaces 101 of the substrate 105 ; (d) connecting the respective application element 210 in the adhesion areas 230 to the at least one surface 101 of the substrate 105, the respective application element 210 in the free areas 240 not remaining connected to the at least one surface 101 of the substrate 105; and (e) mechanical removal of parts of the application element 210 which are not connected to the at least one surface 101 of the substrate 105. The at least one layer of the adhesion promoter 220 is generated in method step (b) by means of a digital printing method.
