Code verification can help reject missing or unreadable codes before cases are packed or products leave the line.
Date code verification systems for checking presence, position and readability of date, batch, barcode and QR codes.
The right recommendation depends on the material, print area, expected contrast, dry time, production speed and how operators will change messages. Lancing can look at your sample pack and advise whether CIJ, TIJ, large character or handheld inkjet is the best fit.
Date, batch, lot, expiry, serial number, barcode, QR code or simple product identification.
Plastic, glass, metal, carton, label, sleeve, pouch, tray, sack, case or coated packaging.
Speed, printhead position, product sensor, encoder, brackets, guards and operator access.
Send the pack type, code example, line speed and available space. We can suggest the best coding route before you commit to a machine.
These pages are written around real packaging problems: substrate, line speed, print position, operator changeover and traceability content.
Check the sample pack, print location, character size and message format before choosing a machine.
Plan brackets, sensor position, encoder use, guarding and operator access around the actual line.
Confirm code legibility, dry time, message control and routine cleaning so the line can run with confidence.
Compare machine types and related print requirements before requesting a recommendation.
Yes. The usual print content is a date, batch number, lot code, expiry date, barcode, QR code or production reference. The best technology depends on the pack surface and line speed.
Ink choice and print position matter. A sample pack check helps confirm contrast, adhesion and dry time before installation.
Most installations can be designed around an existing conveyor or machine using brackets, sensors, encoders and practical guarding access.
Share your product, code content, line speed and pack material for practical UK advice.
A date-code inspection system may need to check more than whether dark pixels are present. Define the actual failure modes and how each result is linked to the correct product.
| Check | What it proves | What it does not prove alone |
|---|---|---|
| Presence | A mark exists in the inspection window. | That the data is correct or readable. |
| OCR/OCV | Characters match an expected string or pattern within configured tolerance. | Formal barcode quality or product identity unless those are integrated. |
| Barcode/2D read | The reader decodes the data under production conditions. | Standards-based verification grade. |
| Formal verification | A compliant verifier grades defined symbol-quality parameters. | Every pack has been inspected online. |
Track the product from printer to camera to reject, including gaps, stops and speed changes. Test no print, wrong print, damaged print, camera fault, reject failure and reject-bin-full states.
