Coating Barcode Data and Printed Text: Check That They Describe the Same Product

A barcode can scan correctly while encoding the wrong product identity. Verify the decoded data against the visible product name, size and approved record before treating the label as ready for production.

Updated · NANOLAB Knowledge

The key distinction

Print quality and data correctness are separate checks. A copied artwork file may retain a previous variant's code even after the title and colour are changed. The review should therefore compare the actual decoded information with the master record rather than approving the label because it resembles the intended design.

Practical checks

  1. Decode the symbol from the production-representative proof.
  2. Compare its identity with the approved product and packaging-level record.
  3. Record approval for the exact artwork revision and repeat the check after relevant changes.

Example

Illustrative example: a 50-millilitre coating label displays the correct text but carries a code assigned to another pack size. A scanner may read it reliably, yet the warehouse or retailer can select the wrong item. The data check catches a problem that visual inspection alone may miss.

Scope and limits

Do not solve a mismatch by changing a downstream product record without reviewing the identifier assignment. This guide does not authorize reuse of a code. Follow the applicable allocation process and preserve the approval trail connecting the printed pack to its intended commercial identity.
