摘要
The present invention relates to an antifalsification document having an embedded secutiry thread, and to a method for producing the same. This security thread is transparent and has a printed pattern on one side and, on the opposite side, a lenticular structure coordinated with the printed pattern. Such threads change their appearance when the viewing angle changes. To produce the security threads, a transparent film impressed with the desired lenticular relief is directed to a printing apparatus in exact register via guide elements having a relief structure that is negative with respect to the film impression, and then divided in a cutting apparatus into individual threads.
