Offline Sheet

Standalone Sheet Inspection for 100% Defect-Free Dispatch

The Offline Sheet Inspection System from Lucid Imaging is a precision, vision-based solution designed to verify every printed sheet before dispatch. With multi-mode imaging and intelligent defect detection, it ensures only fully compliant, defect-free sheets reach the delivery pile.

Solution Overview

Comprehensive Offline Sheet Inspection for Secure and 100% Verified Print Output

The Offline Sheet Inspection System is a standalone, sheet-fed inspection platform built for high-security and quality-critical printing environments. It combines a precision transport mechanism with advanced machine vision to inspect printed sheets comprehensively independent of the production press.

By enabling front-side, back-side, transmissive, UV, and IR inspection, the system detects a wide spectrum of visible and hidden defects. Flexible rejection options ensure defective sheets are automatically identified and segregated, delivering 100% verified output for dispatch.

Where This Solution Is Used

The system is designed for deployment outside the press line, providing final quality assurance:

This placement makes it ideal for validating high-value printed sheets without impacting production throughput.

Inspection Challenges

Key problems this Solution Solves

Customer-Reaching Defects
