Spine-Crossing Security Feature for Secure Booklets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security features for secure booklets, such as passports, are vulnerable to counterfeiting and lack distinctiveness for easy detection by security personnel, as they can be easily replicated using conventional printers and do not provide sufficient anti-counterfeiting measures.
Innovation Solution
A security feature that combines pre-printed and variable printed portions across the spine of the booklet, utilizing different printing techniques and registration systems, making it difficult for conventional printers to reproduce and allowing security personnel to discern authenticity through precise alignment and ink bleeding into stitching threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional printers are used to print security features, then printing cost and ease of manufacture are improved, but anti-counterfeiting capability and security are worsened
Solution Approach 1:
The security feature is divided into two distinct segments: a pre-printed portion applied during booklet manufacturing and a variable data portion printed later during personalization. This segmentation allows each portion to use optimized printing methods while collectively providing high security. The pre-printed portion uses security-specific printing while the variable portion uses standard printing, resolving the contradiction between security and ease of manufacture.
Solution Approach 2:
The pre-printed security feature is applied in advance during booklet manufacturing before the booklet is personalized. This preliminary action establishes a security baseline that cannot be replicated by conventional printers alone, as the pre-printed portion requires specialized printing equipment and techniques that are not available in standard personalization systems.
2Reliability
If static security features like holograms are used, then anti-counterfeiting capability is improved, but adaptability and difficulty of theft are worsened
Solution Approach 1:
The security feature transitions from a static hologram to a dynamic combination of pre-printed and variable data portions. The variable data portion changes for each booklet during personalization, making each security feature unique and adaptable. This dynamic approach maintains high anti-counterfeiting capability while significantly improving adaptability and preventing theft, as each stolen booklet cannot be replicated without access to the variable data printing system.
3Difficulty of detecting and measuring
If printing across the spine is implemented, then security feature detectability is improved, but manufacturing complexity and precision requirements are worsened
Solution Approach 1:
The printing process is segmented into two stages: pre-printing during booklet manufacturing and variable data printing during personalization. This segmentation allows the pre-printed portion to be applied without requiring precise registration across the spine, as the variable data portion is printed later and aligned to the pre-printed features. This resolves the manufacturing precision challenge while maintaining detectability.

AI summary
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.
