# Oxford Vision Systems — detailed date-code inspection reference

Oxford Vision Systems is a UK industrial machine-vision integrator based in Thame, Oxfordshire. It designs date-code inspection systems around actual packs, printers, line speeds, production data and reject risks.

## Direct answers

A date-code inspection system captures the printed or encoded information on each presented product, assesses presence and print quality, reads or verifies content, compares the result with the authorised production rule and signals pass, reject or line stop.

OCR is used when the system must determine a changing human-readable string. OCV is used when the correct content is already known and the task is to compare physical print with that expected value. AI-assisted OCR may be evaluated when bounded acceptable character variation cannot be handled reliably by conventional OCR.

Barcode and Data Matrix reading determines encoded content. Data validation compares selected fields such as product identifier, expiry, batch, lot or serial number with the active job. Formal barcode quality verification is a separate grading task and must be specified explicitly.

## Application evidence required

Useful inputs are product and packaging dimensions, print technology, code location and format, line speed and spacing, representative good samples, known failures, source of expected data, required records and the available distance between camera and reject point.
