GS1 2D Code Printing
In today’s fast-paced global market, the demand for reliable and detailed product identification data is more critical than ever.
The GS1 Data Matrix barcode is set to become the standard for product identification, and the GS1 Sunrise 2027 initiative sets a global target for all retail point-of-sale systems to accept 2D barcodes by the end of 2027.
As more manufacturers worldwide adopt this standard, the need for advanced printing solutions has surged.
What is a GS1 code?
- A GS1 is a two-dimensional (2D) barcode that can encode a large amount of information in a small space, according to some clear standards and rules set out by GS1.
- This data is then able to be read by scanners or mobile devices, making it ideal for product tracking, inventory management, and compliance with regulatory requirements.
- The GS1 2D barcode is particularly valued for its ability to store complex and clearly organised data, such as batch numbers, expiration dates and serial numbers, in a compact format.
- A GS1 2D code encodes data using GS1 Application Identifiers (AIs). Depending on the application, different AIs can be used; some commonly used ones are:
- 01 – 14-digit Global Trade Item Number (GTIN)
- 10 – Batch or Lot Number
- 11 – Production Date (YYMMDD)
- 15 – Best Before Date (YYMMDD)
- 17 – Expiration Date (YYMMDD)
- 21 – Serial Number
Understanding GS1 2D Codes vs GS1 Digital Link
GS1 2D codes, such as the GS1 Data Matrix, are compact barcodes that encode structured product data—like GTINs, batch numbers, and expiry dates—using GS1 Application Identifiers. They’re designed for fast, accurate scanning across supply chains and retail environments.
GS1 Digital Link, on the other hand, transforms these identifiers into web-enabled links by embedding them in a URL format, typically within a QR code. This allows a single scan to connect users to real-time online content—such as product details, traceability data, or promotional pages—enhancing consumer engagement and transparency.
While both formats support GS1 standards, Digital Link adds a powerful layer of connectivity to traditional data capture.
The Growing Importance of GS1
The adoption of GS1 Data Matrix barcodes is on the rise globally, driven by several factors:
- Regulatory Compliance: Many industries, including pharmaceuticals, medical devices, and food and beverage, are increasingly required to comply with regulations that mandate the use of GS1 Data Matrix barcodes for product identification and traceability.
- Supply Chain Efficiency: GS1 Data Matrix barcodes enhance supply chain visibility and efficiency by enabling accurate and rapid data capture. This leads to improved inventory management, reduced errors, and streamlined logistics.
- Consumer Safety: By providing detailed product information, GS1 Data Matrix barcodes help deliver consumer safety. They enable quick and accurate recalls when required and can reduce the risk of counterfeit products entering the market.
- Global Standardization: As a globally recognised standard, GS1 Data Matrix barcodes facilitate international trade by ensuring consistency and interoperability across different regions and industries.

Printing 2D Codes
A 2D can code be printed with a laser coder, continuous inkjet printer or thermal transfer printer. The product, its use, environment and lifecycle will determine which printing technology is most suitable.
When implementing 2D codes, especially in manufacturing or packaging environments, several factors must be considered:
- Print Quality, the information the 2D code carries will not be available if the quality of the print is not good. Poorly printed codes can be unreadable
- Substrate material, what is the substrate made of? This will affect the print methods available, is the surface smooth or rough? A curved surface will distort the code and may make it unreadable.
- Environmental conditions, the temperature, humidity, dust or presence of water on the substrate will affect the code print

FAQ
Commonly used GS1 Application Identifiers include GTIN (01), batch or lot number (10), production date (11), best before date (15), expiry date (17), and serial number (21).
Standard GS1 2D codes focus on encoding structured product data for supply‑chain scanning, while GS1 Digital Link codes use a web‑enabled format that connects the same GS1‑identified product data to online content, such as consumer information, regulatory data, or traceability details.
Sunrise 2027 sets a global target for retailers to accept 2D codes at point of sale by the end of 2027. While immediate compliance may not be mandatory for all manufacturers, many are starting to prepare now to ensure a smooth transition and avoid future disruption.
