Retailers around the world are increasingly embracing 2D codes developed by GS1. Leading brands are recognizing the importance of 2D codes as key elements for connected packaging, improved food traceability, and enhanced consumer trust. As food manufacturers reach a crucial juncture in the implementation, verification, and sharing of product information, Rachael Satchwell, Global Food Sector Manager at Domino Printing Sciences, offers a practical framework to facilitate quicker integration, improve compliance, and enhance operational efficiency.
Concrete Value of 2D Codes
The enthusiasm for 2D codes is clear, yet many manufacturers face challenges rooted in limited operational knowledge. This technology is not solely dependent on retailer demand; rather, 2D codes foster better manufacturing efficiency, ensure food safety, and promote data-driven decision-making.
In the context of food supply chains, 2D codes allow for the capturing of detailed batch and item-level data, which enhances food traceability. This capability enables manufacturers to identify issues with remarkable precision, thereby minimizing the scale, costs, and disruptions associated with recalls. Moreover, it bolsters food safety compliance both within manufacturing facilities and beyond. When real-time data is utilized during production, visibility into product shelf-life is improved, aiding in effective stock rotation and minimizing the risk of short-dated or expired items advancing through the distribution chain.
Furthermore, connected packaging that incorporates 2D codes can strengthen consumer trust by providing greater transparency about allergens, ingredients, sourcing, and sustainability. Access to real-time product data allows for a more agile food supply chain, enabling manufacturers and retailers to exchange insights, enhance coordination in production and replenishment, and decrease waste. Clearly articulating these advantages fosters alignment among internal stakeholders and builds a strong, evidence-backed business case.
Initiating the Adoption of 2D Codes
For many manufacturers, the initial focus is on understanding the operational impacts of integrating this technology rather than just on the technical aspects. Balancing older machinery, new automation solutions, and overtaxed operational teams necessitates a migration strategy that is feasible, low-risk, and closely aligned with everyday production realities.
The aim is to empower manufacturers to embrace 2D codes with minimal disruption to their operations. This process begins by forming a cross-functional team responsible for defining the goals of implementing 2D codes and identifying the necessary data requirements. Next, it is essential to review existing packaging designs to evaluate factors such as space, placement, and the readability of 2D codes, and to determine any modifications required to align with GS1 standards and retailer demands.
Upgrades to current coding and verification systems may also be necessary based on new artwork specifications. It is vital to acknowledge that existing equipment does not necessarily obstruct the adoption of 2D codes, and substantial capital expenditures or extended downtimes are not required. Modern printers, scanners, and vision systems tend to be modular and can be integrated with most established lines with minimal engineering effort.
The integration of 2D codes will generate new types of data and workflows among printers, cameras, PLCs, and IT frameworks. Mapping the flow of information within the production line is crucial for avoiding bottlenecks and mitigating downstream verification challenges.
Enhancing Safety and Efficiency with Automated Verification
Effective verification is an essential component of bolstering food safety. Automated inline verification systems leverage camera-based vision technology along with real-time code grading to ensure that every 2D code is present, legible, accurately structured, and correctly assigned to its respective product.
This automated verification reduces reliance on manual inspections, decreases waste related to unreadable or erroneous codes, and prevents recalls stemming from coding errors or non-compliance. Additionally, it offers solid proof of adherence to GS1 standards, which enhances food safety compliance and builds trust within the supply chain. The final stage involves auditing substrate and ink/ribbon compatibility to ensure durability and high-quality codes across various materials, thereby minimizing print-related production halts.
A controlled pilot phase allows teams to refine the entire process prior to broader implementation. Starting with one or two high-impact SKUs—particularly those with shorter shelf lives or those bound for markets already employing connected packaging—helps in making necessary adjustments to line speeds, lighting, reject logic, and equipment integration under controlled conditions, thereby generating early benefits while limiting disruptions. A successful pilot strengthens the internal business case for a comprehensive rollout, bringing the organization closer to a future-ready, fully connected operation.
Future Prospects for 2D Codes in Food Manufacturing
The move toward 2D codes is indicative of a broader global transition toward more transparent and data-driven food supply chains. This trend aligns with rising consumer expectations, evolving retailer requirements, and the overall push for digitalized, interoperable product information.
There is no need for wholesale replacements of existing equipment. Addressing current knowledge gaps, focusing on achievable operational improvements, and integrating new capabilities with existing systems will pave the way for enhanced confidence and clarity in food manufacturing. By taking proactive and tangible steps now, manufacturers can position themselves at the forefront of the next wave of connected and future-ready food production.
