Description

  The present invention relates to an anti-counterfeit sheet, and more particularly, to a technique that enables authenticity determination by using a separation line at the time of use.

  In the past, counterfeit crimes have frequently occurred in securities such as prepaid cards, various entrance tickets, gift certificates and stock certificates because they are widely distributed and can be exchanged relatively easily. In particular, in recent years, counterfeit products that cannot be easily distinguished from genuine products are relatively easy due to the improvement and popularization of copying, reading, and duplication using electronic devices such as color copiers, scanners, and color printers. Manufacture is becoming possible, and countermeasures against counterfeiting are required.

  Of the prepaid cards, various admission tickets, gift certificates, stock certificates, and other securities such as those mentioned above, the admission ticket is provided with a separation line such as a perforation that can be separated into two. Many are separated into two parts by separation lines. Thus, Patent Document 1 discloses a ticket that enables authenticity determination using the fact that it is separated into two in this way. In the ticket disclosed in Patent Document 1, a colored paper layer having the same shape as the blank paper layer is sandwiched between two blank paper layers, and these are stuck to each other, and the ticket is attached to each of the two blank paper layers. When separated into two by the formed half cut, the colored paper layer breaks with the separation of the blank paper layer, and the colored paper layer is exposed on the separation end face to enable authenticity determination.
