2D Code Printing
What are 2D codes?
2D codes, or two-dimensional barcodes, are data-encoding symbols that store information both horizontally and vertically—unlike traditional 1D barcodes, which only store data in one direction. This dual-axis structure allows 2D codes to hold significantly more information in a much smaller space. For example, while a 1D barcode might store a serial number, a 2D code can store up to 7,000 characters.
There are 2 main types of 2D codes; Data Matrix codes and Quick Response codes (QR codes):
Data Matrix codes are a set of symbols arranged in a square or rectangular grid, which contains a series of dark and light blocks. They are ideal for small items and are commonly used in industrial and healthcare settings.
QR codes can contain a lot of information and can be scanned by smartphones or devices with QR code scanning capabilities. They are used to encode whole URLs and text, geo-location info or any other data.

Benefits of 2D codes
- High Data Capacity: 2D codes can store far more data than 1D barcodes, including text, URLs, and even images.
- Compact Size: Their small footprint makes them suitable for marking on tiny surfaces like electronic components or medical devices and packaging.
- Versatile Scanning: They can be scanned from any angle using camera-based readers or imagers, not just laser scanners.
The rise of 2D codes in packaging
As global supply chains evolve, 2D codes are rapidly becoming the new standard for product identification and traceability.
Unlike traditional 1D barcodes, 2D codes such as GS1 Data Matrix and QR codes can store significantly more information in a compact format—enabling manufacturers to encode batch numbers, expiry dates, and even digital product passports.
GS1 Sunrise 2027 is accelerating the use of 2D codes on consumer products. This initiative sets a global target for all retail point-of-sale systems to accept 2D barcodes by the end of 2027.

2D codes are transforming how products are labelled, tracked, and experienced. At Linx, we’re helping brands stay ahead of this transition with robust, high-resolution coding solutions that meet the demands of modern packaging environments.
Why Linx’s GS1 UK Partnership Matters
Linx’s partnership with GS1 UK reinforces our commitment to trusted, standards‑compliant coding. As an approved provider, our solutions—like the Linx 9000 Series—are validated to print GS1‑compliant 2D Data Matrix codes with accuracy and reliability. This gives customers stronger traceability, easier compliance with global labelling standards, and access to GS1’s support network. It also means Linx features in GS1 UK partner listings, offering added assurance that our technology meets the highest industry benchmarks. Whatever your sector, choosing Linx means choosing future‑proof coding backed by GS1’s global standards.
Printing 2D Codes
A 2D can code be printed with a laser coder, continuous inkjet printer large character markers 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
Yes. 2D codes are ideal for variable data and can securely encode information such as batch or lot numbers, production dates, best‑before dates, and expiry dates within a single compact code.
2D codes can be printed using several industrial coding technologies, including continuous inkjet (CIJ), laser coders, large character marking printers and thermal transfer printers. The most suitable technology depends on the product, substrate, production speed, and operating environment.
Yes. One of the key advantages of 2D codes is their ability to store a large amount of information in a very small space, making them well suited to products with limited print areas.
