Manufacturer's Description

Toppan's Double-sided Demet Thread is an embedded security thread, which like other security threads, can have images or text within its body. What differentiates this thread from standard products is the fact that different images and colours can be observed on either side of the thread. (See the picture below left; red hearts and diamonds on one side, blue spades on the other). Not only this, but when the thread is viewed in transmission, a third image becomes visible (see picture below right: grey clubs) as well as all four images in perfect registration. Furthermore, UV properties can be added to the third image so that a banknote is only authenticated when all 4 elements can be verified.
