2D Code Printing
What are 2D codes?
2D codes, or two-dimensional barcodes, store data both horizontally and vertically. In contrast, traditional 1D barcodes store data in one direction only. As a result, 2D codes hold far more information in a smaller space. For example, while a 1D barcode stores a serial number, a two-dimensional code can store up to 7,000 characters.
There are two main types of 2D codes: Data Matrix codes and Quick Response (QR) codes.
Data Matrix codes use a grid of dark and light squares, arranged in a square or rectangle. Therefore, they suit small items and high-density marking. For instance, manufacturers often use them in industrial and healthcare settings.
QR codes store large amounts of information. In addition, users can scan them with smartphones or camera-based devices. For example, they can encode URLs, text, or geo-location data.

Benefits of 2D codes
- High Data Capacity: 2D codes store more data than 1D barcodes. For example, they include text, URLs, and images.
- Compact Size: Their small size makes them ideal for limited space. Therefore, they suit electronics, 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 becoming the new standard. In particular, they improve product identification and traceability.
Unlike traditional 1D barcodes, two-dimensional 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 two-dimensional 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.

Furthermore, Linx appears in GS1 UK partner listings. Therefore, customers gain added confidence in our technology. Ultimately, you choose a future-ready solution backed by global standards.
Printing 2D Codes
You can print 2D codes using several technologies. For example, these include laser coders, continuous inkjet printers, large character markers, and thermal transfer printers. However, the right choice depends on the product, environment, and lifecycle. Therefore, you must match the technology to your application.
When implementing two-dimensional codes, consider the following factors:
- Print Quality, Poor quality reduces readability. As a result, systems may fail to access the data.
- Substrate material, The surface affects print performance. For example, rough or curved surfaces can distort codes.
- Environmental conditions, Temperature, humidity, dust, and moisture affect print quality. Therefore, controlled conditions improve results.

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.
