Controlled imaging
Purpose-designed lighting, camera position and product presentation improve repeatability.
OCR, OCV & variable print verification
Date-code inspection and automatic rejection
Verify that the right code is present, legible and correct before the product leaves the line. Failed packs are positively tracked and rejected.
Representative engineered production applicationThe inspection result is only useful when the right product leaves the line.
Variable print is time-sensitive and product-specific. The inspection recipe can check date presence, format, position and expected content for inkjet, laser or thermal-transfer codes. OCR reads the printed characters; OCV compares them with an expected value or pattern.
Good imaging depends on controlled presentation, lighting and focus. We develop the inspection and reject station together so the decision remains linked to the correct product even where the printer, camera and reject point are separated along the conveyor.
How our integration works →Typical pass / fail criteria
Decisions the reject system can act on.
The final inspection capability depends on the selected equipment, product presentation and agreed acceptance criteria. Sample trials are used where practical.
✓Use-by date
✓Best-before date
✓Batch or lot code
✓Missing or incomplete print
✓Incorrect code format
✓Print position and contrast
Engineered as one sequence
From detection signal to independently confirmed removal.
Recipe logic
Expected date, format and code rules are managed with the product setup.
Automatic removal
Failed packs are tracked to a suitable reject device with optional verification.

What is the difference between OCR and OCV?+
OCR reads characters and returns data; OCV compares the observed print with an expected character or string. The right approach depends on the control objective.
Can the system check changing dates?+
Yes. Expected values can be recipe-based, entered by an authorised operator or provided through an agreed production interface.
Can it inspect inkjet and laser codes?+
Yes. Trials confirm the best camera, lens, lighting and image settings for the substrate and print method.
