Printed security feature for secure booklets
View Patent ↗A security feature for use with secure booklets, especially those having a spine, for example passports, identification booklets and other types of ID3-sized documents. In one example, the security feature is printed across the spine of the booklet onto two adjacent pages. Most conventional, commercially available printers are unable to print across the spine, and therefore would be unable to reproduce the security feature. In addition, in the case of a booklet, for example a passport, that uses a stitching thread to secure the pages together, ink from the printed image bleeds into the thread. The presence or absence of ink in the thread can then act as an indicator as to whether or not the booklet is genuine or a counterfeit. Another security feature includes registration of a pre-print portion and a variable print portion that is applied during booklet personalization to form a combined image.
