AI Technical Summary

Technical Problem

Existing security documents with optical security elements, such as those featuring windows with light-diffusing structures, require complex and time-consuming production processes due to their delicate nature, necessitating separate substrates and multiple structured layers, which are costly and inefficient.

Method used

A three-dimensional image generation structure is integrated into a viewing section of security documents, formed on an outer surface without a separate support, using a laminating process with a laminating plate that has a high line resolution and structural depth, allowing for simple, fast, and cost-effective manufacturing.

Benefits of technology

This approach enables the production of security documents with high protection against forgery and fraud, utilizing moving images generated by light refraction, while eliminating the need for additional coatings and separate supports, thus reducing production costs and time.
