Zero-Error Label Production: High-Speed OCR & Barcode Inspection System
High-Speed OCR & Barcode Verification Problem Statement: In the mass production of product labels, ensuring that the printed human-readable text (OCR) matches the machine-readable barcode is critical. Manual inspection on high-speed reel-to-reel machines is impossible, leading to risks of mixed data, missing prints, or unreadable codes reaching the end customer. The Challenge: The client needed a system capable of inspecting every single label on a moving roll. The challenge involved not just reading the data, but performing a Dual Validation Cross-check—verifying that the alphanumeric string (OCR) perfectly matches the decoded Barcode data in real-time, while also controlling the machine’s motor to stop immediately upon detecting a defect. ...
