To create watermark labels, customers provide Graphic Products with an electronic image of their desired graphic or text. Within a week, customers can receive a supply of their custom UV watermark tape. For added security, the tape can be used with tamper evident destructible tapes or tamper-evident “VOID” tapes.
An example of a potential UV watermark tape application is a counterfeit-thwarting application used by Tri-Met, Portland Oregon’s public transit provider. Tri-Met applies a special hologram tape to bus, commuter rail and street car passes. Without this device, crooks would be able to inexpensively color copy the bus passes and Tri-Met would lose $100 with each copy. As the hologram image cannot be reproduced by copiers, it is nearly impossible to counterfeit Tri-Met passes.
