**Markem-Imaje CoLOS Software: The Core Solution for GS1 Digital Link and 2D Barcode Adoption**
The landscape of industrial coding and product identification is undergoing a significant shift, moving from traditional 1D barcodes to more data-rich 2D codes like QR Codes. This evolution is largely driven by the adoption of the GS1 Digital Link standard, a framework designed to turn static product identifiers into dynamic digital keys. To understand the technical and operational impacts of this transition, we spoke with Viktor Hermansson, Marketing Communication and Business Enablement Director at Markem-Imaje. As the provider of the CoLOS software suite, Markem-Imaje is at the forefront of enabling manufacturers to not only comply with these new standards but to unlock new value streams through their packaging.
### **The Shift to 2D: Compliance and Implementation Challenges**
The transition from 1D to 2D barcodes and the implementation of the GS1 Digital Link standard represent a fundamental change in how products interact with the digital world. Unlike 1D barcodes, which hold limited data, 2D codes like QR codes can store vast amounts of information, enabling direct consumer engagement, enhanced traceability, and real-time inventory management.
“The transition impacts every entity in the supply chain, from manufacturers to retailers,” explains Hermansson. The core of the challenge lies in data definition and verification. Companies must first decide what data to encode and how it will be used. This often involves decisions about whether to completely replace 1D barcodes or operate in a hybrid mode during a transition period.
For manufacturers, the implications vary based on their production methods:
* **Pre-printed Labels:** Companies using pre-printed labels must ensure their label suppliers can generate GS1-compliant 2D codes and, crucially, verify them post-print to guarantee scannability and compliance.
* **On-demand Printing:** For those printing codes directly onto packaging, the requirements are more technical. They need printing equipment capable of producing high-contrast, standards-compliant codes at line speed, coupled with a robust design system and an in-line vision verification system to catch errors before products leave the facility. The ultimate goal is to integrate this process seamlessly without impacting the Overall Equipment Effectiveness (OEE).
### **Markem-Imaje CoLOS: A Comprehensive Solution for the Digital Age**
In response to these evolving needs, Markem-Imaje has developed its CoLOS (Connected Logistics Suite) software, a platform designed to manage the entire lifecycle of packaging and marking.
CoLOS is not just a barcode generator; it is an end-to-end workflow automation system. Its core strength lies in its ability to connect enterprise resource planning (ERP) and manufacturing execution systems (MES) directly to the production line. This connectivity allows for the dynamic injection of unique, variable data—such as batch numbers, expiration dates, and serial numbers—directly into a GS1 Digital Link QR code at full production speed.
**Key Features and Capabilities:**
1. **End-to-End Workflow Automation:** The software ensures that the correct, compliant code is on the correct product, automating the process from design to verification and rejection management.
2. **”Single Version of Truth”:** By linking packaging design, barcode data, and production data from disparate systems, CoLOS guarantees data consistency across the entire supply chain.
3. **Verification and Inspection:** Integrated vision systems validate 100% of printed codes, ensuring print quality meets GS1 standards and preventing faulty products from reaching consumers.
4. **Connected Consumer Enablement:** Beyond compliance, CoLOS facilitates consumer engagement by managing the data behind the QR code, allowing for dynamic content, promotions, and direct brand interaction.
### **Enabling Innovative Use Cases and Regulatory Compliance**
The GS1 Digital Link standard, powered by CoLOS, enables a wide array of innovative applications that extend far beyond simple product identification.
* **Traceability and Recall Management:** Companies can track products from farm to fork, enabling rapid and precise recalls, thereby enhancing food safety and consumer trust.
* **Anti-Counterfeiting and Brand Protection:** By embedding unique identifiers, brands can authenticate products and prevent the sale of counterfeits.
* **Enhanced Consumer Engagement:** Consumers can access a wealth of information, including nutritional details, recipes, and sustainable sourcing information, directly from their smartphones.
* **Sustainability and Circular Economy:** The technology supports initiatives like improved recycling instructions and reducing food waste by providing accurate “best before” dates.
Regarding compliance, CoLOS is designed to meet global regulatory requirements. It supports sector-specific needs, particularly in industries with stringent traceability and safety standards, ensuring that manufacturers can meet regulations such as those for pharmaceuticals, food, and consumer goods.
### **Conclusion: The Strategic Advantage of an Integrated Approach**
The adoption of 2D barcodes and GS1 Digital Link is not merely a technical upgrade; it is a strategic business imperative. It transforms packaging from a passive container into an active, intelligent component of the supply chain and a direct channel for consumer engagement.
For IoT enterprises and manufacturers, the benefits of a solution like CoLOS are multifaceted. It future-proofs operations by ensuring compliance, reduces the risk of costly errors and recalls, and unlocks new revenue and data opportunities. By handling large data volumes at speed and integrating seamlessly with existing IT and OT infrastructure, CoLOS provides the robust, secure, and scalable foundation required for success in the modern, connected economy.
