Security Paper Inspection System
Comprehensive Inspection for Secure & Defect-Free Security Paper
The Security Paper Inspection System from Lucid Imaging is a high-precision, vision-based solution designed for security paper and banknote paper manufacturing. It ensures early detection of defects and reliable verification of embedded security features protecting quality, security, and compliance from the very first stage.
Solution Overview
Advanced Multi-Mode Inspection for Secure Paper Integrity
Security paper forms the foundation of banknotes and identity documents, where defects or inconsistencies can compromise security and downstream processes. The Security Paper Inspection System performs comprehensive front-side and back-side inspection, detecting both high-contrast and low-contrast defects that are difficult to identify manually.
With optional transmissive inspection for watermarks, security threads, and electrotypes, and invisible UV inspection for security fibers and covert elements, the system ensures that every sheet or web meets strict quality and security standards before printing begins.
Where This Solution Is Used
The system is engineered for flexible deployment across security paper workflows:
- Inline on paper production lines for continuous monitoring
- On rewinders, to verify quality before slitting or dispatch
- On sheeters, for inspection of cut security paper sheets
- As a standalone offline system, for sampling, audits, or investigations
This flexibility allows inspection without disrupting existing production setups.
