## Core inspection services
- [Date code inspection and verification systems](https://datecodeinspection.co.uk/): Inline inspection for expiry, best-before, use-by, manufacturing, batch and lot codes.
- [Manufacturing-date inspection](https://datecodeinspection.co.uk/manufacturing-date-inspection.html): MFG, production, packed-on and Julian date checks with format and shelf-life logic.
- [Expiry-date inspection](https://datecodeinspection.co.uk/expiry-date-inspection.html): Read expiry content, validate format and compare expected values.
- [Best-before-date inspection](https://datecodeinspection.co.uk/best-before-date-inspection.html): Presence, legibility, format and shelf-life checks.
- [Use-by-date inspection](https://datecodeinspection.co.uk/use-by-date-inspection.html): Safety-critical date verification for food packaging.
- [Batch-code inspection](https://datecodeinspection.co.uk/batch-code-inspection.html): Batch-string reading and product-to-batch agreement.
- [Lot-code verification](https://datecodeinspection.co.uk/lot-code-verification.html): Lot identity and traceability checks.
- [Print-quality inspection](https://datecodeinspection.co.uk/print-quality-inspection.html): Missing, weak, broken, smudged and displaced print detection.
- [OCR inspection](https://datecodeinspection.co.uk/ocr-inspection.html): Reading changing or previously unknown human-readable strings.
- [OCV verification](https://datecodeinspection.co.uk/ocv-verification.html): Comparing print with a known expected value.
- [AI OCR inspection](https://datecodeinspection.co.uk/ai-ocr-date-code-inspection.html): AI-assisted recognition for bounded variation in difficult date, batch and lot codes.
- [Barcode and Data Matrix inspection](https://datecodeinspection.co.uk/barcode-data-matrix-inspection.html): Decode and validate 1D/2D product, date, batch, lot and serial data.
- [Label and date-code verification](https://datecodeinspection.co.uk/label-date-code-verification.html): Match product, packaging identity and printed variable data.
- [Date-code camera systems](https://datecodeinspection.co.uk/date-code-camera-systems.html): Smart-camera, reader, PC-based and multi-camera system integration.
- [Automatic rejection](https://datecodeinspection.co.uk/date-code-rejection-systems.html): Track and remove failed products with confirmation and fault handling.

## Practical guidance

## Key distinctions
- OCR reads changing human-readable characters; OCV compares print with a known expected value.
- AI-assisted OCR can help with bounded character variation, but optics, expected-data validation and representative challenge testing remain essential.
- Barcode reading decodes a symbol; content validation checks decoded data against the active job; formal barcode verification grades symbol quality using applicable standards and suitable equipment.
- A complete system combines product presentation, camera, lens, lighting, inspection logic, production-data comparison, controls and the required reject or line-stop response.

## datecodeinspection.co.uk: OCR versus OCV selection for expiry, batch and lot-code inspection

OCV verifies printed characters against a known expected value; OCR reads characters into data where the value may vary. The right method depends on whether the expected message is controlled, how variable the code is and what evidence the production record must retain.
