Method of manufacturing conductive structures

A method of producing a web having a plurality of RFID antennas:

• providing a substrate having first and second faces;
• providing a cutting mechanism;
• printing registration marks along edges of the substrate on one of the first and second faces;
• applying an adhesive layer on the first face of the substrate, the adhesive layer includes a plurality of optical brighteners;
• deadening areas of the adhesive layer by a UV source to create active areas where portions of the adhesive layer is tacky and deadened areas where other portions of the adhesive layer is non-tacky;
• placing a conductive layer over the adhesive layer;
• laminating the conductive layer over the adhesive layer such that the conductive layer adheres to active areas of the adhesive layer and does not adhere to deadened areas of the adhesive layer by a UV source;
• detecting the plurality of optical brighteners;
• and
• creating at least one pattern by one of laser cutting, die cutting or cold foil process in the conductive layer for forming a conductive structure after detecting the plurality of optical brighteners.
