Inspect the identity before it moves on

Industrial vision verification systems.

Verify codes, characters, labels and product identity in real time, with controlled rejection and a clear inspection record.

Traceability verification

Confirm that the physical product carries the right digital identity.

Printing or applying a code does not prove it is present, readable or correct. Vision verification closes that gap by reading the product after marking or labelling and comparing the result with the expected data.

The inspection can provide a simple pass or fail, a decoded value, a quality measure, an image record or a combination of results. It can also control a reject device and confirm that the failed product was removed from production.

Inspection capability

Read, compare, grade and reject.

The inspection task should be defined precisely. Reading a code, verifying its data and formally grading print quality are related but different requirements.

1D barcode inspection

Read linear codes, confirm the expected symbology and data, and check that the code is present in the defined area.

2D code verification

Decode Data Matrix and QR codes, parse required data elements and compare them with the production record.

OCR & OCV

Read variable characters or verify printed text against an expected string, format, pattern or approved reference.

Code quality assessment

Measure appropriate code-quality characteristics using a defined setup when formal verification or grading is required.

Database comparison

Compare the observed identity with the active order, approved item, allocated serial or connected data source.

Reject integration

Trigger the appropriate reject, track the failed item and confirm its removal with fail-safe monitoring where required.

Closed-loop inspection

A clear decision for every inspected product.

Good inspection architecture manages the product from trigger to confirmed disposition, including the uncertain conditions between them.

Acquire

Trigger the image at the right position with controlled optics, lighting and product presentation.

Decode

Locate the target, read its content and calculate the configured inspection results.

Compare

Check the result against the expected product, order, serial, pattern or quality threshold.

Act

Pass, reject, stop, alert or record the product according to agreed exception logic.

Designed for the line Optics, lighting, motion and handling matter as much as the inspection software.

Image quality first

Reliable verification starts before the camera.

Blur, glare, low contrast, label movement, print variation and inconsistent presentation can make a capable algorithm unreliable. We design the imaging condition and the production response together.

Reading vs verification

Specify the result you actually need.

This distinction affects the camera, optics, software, calibration, installation and acceptance test.

Presence checkConfirms that a code-like feature appears in the expected region. It does not necessarily prove that the content is readable or correct.

Code readingDecodes the symbol and returns its data when the installed system can read it under production conditions.

Content verificationCompares decoded data with the expected order, item, batch, serial or database record.

Quality gradingMeasures defined print-quality characteristics under a controlled verification method and reports the appropriate grade or metrics.

System validationDemonstrates the complete installed inspection and rejection process against agreed application-specific acceptance criteria.

Have a code, label or print-quality challenge?

Send representative samples and details of the production speed, code, substrate, position and acceptance requirement. We can define a suitable verification route.
