What is QR Code and Data Matrix Code?

In today’s era, 2D code is needed to disseminate information quickly and efficiently. QR codes are also easy for ordinary people to make, so this is one of the reasons why these 2D codes are easy to find. However, apart from the QR code, there are two other dimensions: the Data Matrix code. This code is often used in various industries and fields, and the application is quite wide.

QR and Data Matrix Codes Appearance

If not observed, the two types of two-dimensional code are difficult to distinguish because both are pixels packed in a box.

You need to look more closely and carefully. QR codes and matrix codes have different appearances, as well as the technology applied.

The QR code has three larger squares in the corners. The three boxes are useful for identification and embedded data for reading.

The Data Matrix code itself uses an L-shaped solid black border as the discoverer’s pattern.

QR and Data Matrix Code’s Function 

Both are two-dimensional scannable images that could be used to hold alphanumeric information. Even though they have some similarities, both of them have their own aspects which make them stand out from the other.

QR codes are more preferred in the market because of their capability to hold more data. They can store 7,089 numeric or 4,296 alphanumeric characters. QR codes also have compatibility with Kanji/kana characters.

Like the large data storage capacity, QR codes need to come at a much larger physical size. Compared to Data Matrix codes that have higher information density, they could be printed at smaller sizes. It makes them ideal for tracking small products, like computer parts and motherboards, or on rounded surfaces.

But with the smaller printed size, Data Matrix codes only have a maximum data capacity of 3,116 numeric or 2,335 alphanumeric characters. Also, this kind has no compatibility for other types of characters which significantly narrows down its flexibility.

Thus, Data Matrix codes have more industrial applications while QR codes dominate the general and consumer market.

QR and Data Matrix Code’s Readability 

Data Matrix code tolerance for physical changes and damage are high. The percentage that it can tolerate is 30%. They have algorithms that allow the code readers to recreate and fill up the damaged part, making the code readable.

QR codes only have a tolerance between 7-30%, depending on the size of information stored.

However, there is also a minimum contrast requirement between the shade of the darker and lighter pixels for the readability of the codes.

For QR codes to be read properly, they must be printed with colours that are 40% contrasting with each other. But Data Matrix only needs 20% contrast. Thus, the Data Matrix code can be printed in almost the same colour.

Therefore, the code can be etched on a green motherboard and still be read properly by a scanner. So, it depends on the colours printed.

QR and Data Matrix Code’s Reader

Data Matrix codes can be scanned using either the code scanner or omnidirectional camera scanner. Because it is intended for industrial use, some smartphone cameras need third-party apps.

On the other hand, QR codes can be scanned using a smartphone camera without a third-party app. It gives QR codes more shine over Data Matrix codes in customer-facing applications. 

QR and Data Matrix Code’s Printing

For printing or product labelling, it is necessary that the 2D codes are printed correctly. To ensure that it’s important when selecting the printer. It is important to pay close attention to details such as the printing application and the accompanying code verification system.

While Data Matrix and QR codes provide greater tolerance for errors than traditional 1D barcodes, it is crucial to ensure the codes are printed right and clean. Hence, the codes are functional to be used by consumers and retailers.

Choosing the Best Printer for 2D Code

Using a printer that is reliable, easy to use, and has good performance is a must for producing labelling 2D Codes. The DSI printer that is only distributing Linx products is the product you could use. 

The product family for the 8900 series is the right one for printing 2D code. The 8900 series includes 8900 printer, 8910 printer, 8920 printer, and lastly, 8940 printer have the same common features to capable printing 2D code.

Printing with a Linx printer guarantees many benefits. The user interface is mistake-free editing with a message update button. Not only that, the cabinet and ink system are an easy self-service module change. Also, the print head has high print speeds and minimal intervention.
