The Increasing Complexity of Modern Product Labeling

Product labels are becoming increasingly complex. Companies today have to take many factors into account:

  • Country-specific regulatory requirements
  • Multilingual Content
  • Variable Data and Serialization
  • Frequent Artwork Updates
  • Different Packaging Options

It is becoming increasingly difficult for operators to reliably identify the correct version. Traditional manual processes are reaching their limits in this regard.

The Real Risk: The Final Stage of Label Inspection

Even if the digital reference has been approved correctly, it is necessary to ensure that the printed and applied label actually meets the requirements:

This “last mile” between digital data and the physical product is one of the most critical phases in production.

From Digital Reference to Automated Label Verification

This is exactly where QualiVision’s solution comes in.

Through integration with the OPAL label management system, the approved digital reference is transferred directly to the QualiVision Label Inspection System.

This means:

No need to set up label layouts and fonts separately

No manual configuration

No inconsistencies between systems

Changes made in OPAL Label Management are automatically applied as new inspection references. Manual adjustments or re-teaching in the vision system are no longer necessary.

The QualiVision system automatically performs a label inspection based on the approved reference data.

The Benefits of Integrating QualiVision and OPAL:

  • Direct Use of Data Released from OPAL for Quality Control
  • Automated Label Inspection Without Re-Teaching
  • Significantly shorter changeover times
  • Minimal operator intervention
  • Maximum process reliability
  • End-to-End System Integration (Label Management ↔ Production)
  • Automated and Consistent Documentation

More Than Just Content Verification—Smart Label Inspection with Machine Vision

The QualiVision solution offers a comprehensive machine vision label inspection and verification system. Immediately after printing, legibility, print quality, and print data are checked. After labeling, the system can also verify correct application, product-label matching, and other product characteristics.

Print and Content Review

  • Legibility and print quality of plain text, codes, and variable data with the QualiVision LegibilityCheck
  • Text and variable data in Latin and non-Latin writing systems (e.g., Chinese, Arabic, or Cyrillic)
  • Barcode Verification (1D, QR, Data Matrix, GS1-compliant)
  • Completeness and Accuracy of Print Data
  • Retrieving Serialized Data Using OCR

Application and Product Testing

  • Label Position and Orientation
  • Application errors such as wrinkles or misalignments
  • Product-Label Mapping to Prevent Mix-ups
  • Geometric, positional, and completeness inspections of the product

In regulated industries in particular, automated in-line inspection helps detect defects early on and prevent scrap and product recalls.

      Automated Documentation and Full Traceability

      Another key advantage is the complete digitization of the documentation.

      The QualiVision solution automatically generates:

      • Test Reports
      • Audit Trails
      • Quality Statistics
      • Photographic documentation of defective labels

      This largely eliminates the need for manual documentation and archiving processes.

      The Closed-Loop Quality Cycle – Integrated with OPAL

      The integration of QualiVision and OPAL Label Management creates a seamless end-to-end process:

      Diagram titled “Verification Cycle” showing five consecutive phases in a closed loop: 1. Approval, 2. Production, 3. Verification, 4. Documentation, and 5. Optimization. The phases are connected by arrows and illustrate a continuous process of improvement and verification that, after optimization, begins again with approval.

      The quality data can be fed directly back into higher-level systems (MES, ERP, QMS).

      Result: A fully digital quality cycle—from artwork approval to documented label inspection.

      Conclusion: From Label Management to True End-to-End Label Verification

      Digitization doesn’t end with artwork approval.

      It is only through the combination of:

      • OPAL label management
      • and automated label inspection using QualiVision

      This results in a comprehensive solution.

      Companies benefit from:

      Maximum process reliability

      Reduced error and compliance risks

      Faster production processes

      Complete Transparency and Traceability

      The successful integration of QualiVision into OPAL demonstrates:

      The future of product labeling lies in the intelligent integration of label management and automated label inspection.
