Abstract
Tickets for concerts, conventions, sports, and like events, have a security feature to assist in preventing counterfeiting. A stretchable security thread is disposed in a piece of paper stock extending so that it intersects, with portions lying on either side of, a line of separation in the piece of paper stock (and/or is parallel to the length of the ticket). The line of separation typically is a perforation. The security thread is a stretchable material, such as polyester, and may have microprinting. When the ticket is detached at the line of separation, the security thread does not initially separate but rather stretches to provide a visual (and tactile) indication between the separated portions of the paper stock before it breaks. Such tickets are produced from a web of material having the security threads, which web is printed, and then cut into sheets for delivery to a customer who then can apply variable printing. If making perforations, care is taken not to make a perforation gap at the intersection of a security thread with a line of separation.
