2D code inspection
Verify QR and Data Matrix codes at full production speed
Compact 2D codes carry more information in less space, but cell damage, poor contrast, reflective packs and print distortion can quickly erode performance. We inspect QR, GS1 QR, Data Matrix and GS1 DataMatrix codes in-line and act on every failed result.
Application focus
Decode, inspect and validate the data structure
The station confirms the symbol is present and decodable, then checks captured content against the required rules. Depending on the application, that may include a fixed URL, GTIN, batch, expiry date, serial number or a complete GS1 element string. Print-quality monitoring gives early warning of contamination, ribbon wear, insufficient contrast or geometric distortion.
Camera resolution and lighting are chosen from the physical code size, module size, print method, substrate and inspection distance. Trials with real products allow us to prove a practical inspection window before final integration.

A proven project route
From sample to a production-ready inspection
We define the pass criteria first, prove the imaging and data logic, then integrate the complete inspection and reject sequence.
Application review
Product, code, substrate, speed, line layout and data requirements.
Sample trials
Optics, lighting, resolution and achievable tolerance tested on real packs.
System integration
Camera, controls, guarding, reject and upstream interfaces engineered together.
Commissioning
Recipes, fault handling, training and agreed acceptance tests completed.
Common questions
What manufacturers ask us
Every line is different. These are the practical questions that shape a dependable barcode verification project.
Ask an engineerCan the system check the destination of a QR code?+
It can confirm the encoded URL or data matches an approved value or pattern. Testing the availability and content of the web destination is a separate control that can be specified if required.
Can it verify very small Data Matrix codes?+
Potentially. We determine feasibility from module size, print quality, surface, line speed and available camera position, then validate with samples.
Can you inspect multiple 2D codes on one label?+
Yes, where the imaging resolution and field of view allow each required symbol to be resolved reliably.
