Data Matrix vs QR Codes: Choosing the Right Code For Your Needs

, , , ,

Have you ever wondered about the small, square barcodes often found on electronic devices, tools, and appliances? While they might resemble QR codes, they’re actually Data Matrix codes, essential components of modern manufacturing processes.

Unlike QR codes, primarily used for consumer-facing applications like websites and social media, Data Matrix codes are designed for efficient data storage and traceability. They’re the only 2D barcodes officially approved by GS1 for regulated healthcare items, emphasizing their reliability and accuracy.

QR codes on the other hand are larger and contain more data, such as website URLs, and can encode information in numeric and alphanumeric form as well as Kanji and other multi-byte character sets. 

No matter what industry, when it comes to industrial traceability for manufacturers, choosing the right type of code can leave a production run riddled with misinformation and the chance of getting lost. 

Let’s break down the differences and similarities between QR and Data Matrix codes and why the latter is the preferred choice of most manufacturers.  

 

QR vs Data Matrix Codes

Understanding the distinctions between QR codes and Data Matrix codes is crucial for manufacturers looking to optimize their processes. Both codes are two-dimensional (2D) barcodes and consist of a pattern of squares that can be read by a barcode scanner. However, there are notable differences in their shape, size, and data capacity.

What is a QR Code?

QR Code

QR codes are two-dimensional barcodes scanned by smartphones or other devices with cameras. They store information in a matrix of black-and-white squares, which can be interpreted to reveal data such as URLs, text, or contact information. Think of them as digital links that can be quickly accessed by simply scanning them with your phone.

 

What is a Data Matrix Code?

Data Matrix CodeData Matrix codes are another type of two-dimensional barcode, but they are smaller and more compact than QR codes. They are often used in industrial settings, such as manufacturing and logistics, because they are highly durable and can be scanned even when damaged or dirty. Data Matrix codes are useful for tracking individual items or components throughout production, ensuring accuracy and efficiency.

 

Direct Part Marking 

While both QR and Data Matrix codes are in the public domain and can be used royalty free, Data Matrix codes have become the standard for anti-counterfeit measures, part identification, and internal tracking because they feature advanced error-correcting techniques that are more robust than QR codes. 

This presents a unique benefit for manufacturers that need to ensure their products can be identified if part of the mark gets damaged or impeded. 

Particularly necessary for complex and high stakes industries such as medical, aerospace, and defense, where hundreds to thousands of components are needed in order to assemble a finished product, Data Matrix codes can be read even if up to 50% of the mark gets damaged. 

QR codes on the other hand have steadily been adopted in consumer-facing applications. These codes can be found everywhere from business cards to product packaging, containing links to websites, resumes, premium offers, and even restaurant menus. 

QR codes have a lower level error-correcting built in, and can be rendered useless with even slight ware and tare. Just 30% of a QR code needs to be damaged before it becomes unreadable. 

While these codes are perfect for consumer-forward use, marking a component or part with a QR code presents a real danger for misidentification pending the mark gets damaged.

Part marking systems are crucial across various industries for tracking, identification, quality control, and regulatory compliance. Two popular methods for part marking are dot peen marking and laser marking. Each has its advantages, disadvantages, and typical applications based on factors such as material compatibility, precision, cost, and durability of the mark. Here’s a detailed discussion and comparison:

Dot Peen Marking

Dot peen marking involves a pneumatically or electromechanically driven pin that rapidly indents the material surface with dots to create numbers, letters, logos, or 2D Data Matrix codes. The resulting mark is a series of closely spaced dots forming lines or shapes.

This type of marking is widely used in automotive, metalworking, and aerospace for marking components where the durability of the mark is critical. This can range from the process of adding serial numbers on engine parts to VIN numbers and tool identification.

Dot peen is often preferred for harder materials and where surface deformation is not a concern, whereas laser marking offers broader material compatibility and is better for delicate or heat-sensitive materials.

Advantages of dot peen marking include:

  • The marks are deeply embedded into the material, making them highly durable and resistant to wear over time, even in harsh environments.
  • Generally less expensive than laser marking systems, both in initial investment and maintenance costs.
  • Effective on a wide range of materials, including metals, plastics, and harder materials.

Disadvantages of utilizing dot peen marking include:

  • Typically slower than laser marking due to the mechanical process of indenting each dot.
  • The mechanical impact may deform delicate parts or surfaces.
  • While precise, it may not achieve the fine detail possible with laser systems, especially on very small or complex designs.

Laser Marking

Laser marking uses a high-intensity light beam to slightly alter or ablate the surface material, creating high-contrast marks without contacting the material.

Techniques include engraving, annealing, etching, and foaming, depending on the material and desired effect.

Laser marking wins in precision and detail, making it preferable for industries requiring intricate designs or small text. It is considered ideal for barcodes, UID codes, QR codes, and detailed logos.

 

 

Laser marking is commonly used in:

  • Electronics
  • Medical devices
  • Aerospace
  • Jewelry
  • Applications where precision, minimal part damage, and aesthetic quality of the mark are paramount.

Three main advantages of laser marking are as follows:

  • Capable of producing highly detailed, precise marks with excellent resolution. Suitable for small text, complex logos, and even photographic images.
  • Can mark a wide range of materials, including metals, plastics, ceramics, and even sensitive materials without damaging them.
  • Fast marking process due to the non-contact nature of the laser, which can move quickly over the target surface.
    Easily programmable for variable data (e.g., serial numbers), integration into production lines, and minimal maintenance.

Meanwhile, some disadvantages of this marking system include:

  • Higher initial investment and operating costs compared to dot peen marking
  • Safety precautions necessary due to the use of high-powered lasers
  • Certain materials may not mark well or require specific laser types (e.g., fiber, CO2, UV) to achieve the desired contrast or effect.

Note: The size of the parts can also be a factor, as even huge parts can easily be marked with a handheld dot peen marking system, while lasers are not developed to the point they can be utilized for large parts.

Comparing Dot Peen and Laser Marking

Laser marking offers unparalleled precision and flexibility for a wide range of materials and applications, while dot peen marking provides a cost-effective, durable solution for simpler marking tasks.

The choice between dot peen and laser marking ultimately depends on the specific requirements of the application, including:

  • The type of material
  • The desired mark quality and durability
  • Production speed
  • Budget constraints

Marking System Choices | Next Steps

Laser marking and dot peen marking are both widely used in industrial applications for the permanent marking of parts and products, but they differ significantly in their mechanisms and outcomes.

Laser marking utilizes a high-intensity light beam to etch or mark the surface of a material, allowing for precise, high-resolution marks including barcodes, QR codes, and intricate graphics, while dot peen marking involves a pneumatically or electromechanically driven pin that physically impacts the surface to create dots forming numbers, letters, or simple logos. Both are useful in any number of industries – depending the needs and expectations of the product line in question.

Dot Peen Marking Basics

What Is Dot Peen Marking?

, , , , , ,

Dot Peen Marking Basics

Ask anyone inside the industrial manufacturing industry – part-marking is crucial to component traceability when working with large quantities. And while several different types of part-marking exist, Dot Peen marking technology has been a preferred solution for many years. 

At a high level, Dot Peen marking machines use either electromagnetic or pneumatic force to rapidly oscillate a stylus, in turn indenting the marks onto the surface of the part. 

One of the advantages of Dot Peen is that it’s very flexible and can be used in either manual or fully automated production lines. A lot of the applications Dot Peen serves are manual applications, however, with modular Dot Peen systems, you can start with a portable system and later convert it to an in-line system for integration with fully automated production lines.

 

The Basics | What is Dot Peen Marking?

If you took apart a Dot Peen machine, one of the most important components you would find is a carbide or diamond-tip stylus. 

The Dot peen process is considered a “low-stress” marking method because the mark is generated via material displacement rather than material removal.  The carbide stylus strikes the material surface to produce the mark via a series of cold-formed stamped dots. Compared to Laser Marking Systems, Dot Peen does not induce thermal shock to the part surface since the material is cold-stamped rather than super-heated to produce the mark.  

Dot Peen systems are commonly used by manufacturers in the aerospace and oil & gas industries where low-stress marking is required, such as tubular and flow control products that are exposed to extreme pressure differential in the oilfield. 

Dot Peen marking is viable for material hardness up to 63 HRC. Typically, when a part hardness is greater than 63 HRC, laser marking systems are recommended. 

All of Technomark’s Dot Peen machines rely on an electromagnetic solenoid to actuate the marking stylus. Dots are plotted in an X/Y plane via electronic control for precise placement of the Dot pattern. Using electromagnetic force versus pneumatic also provides a greater level of control of both the depth of the mark as well as the ability to mark contoured or complex surface.

Dot Peen Marking: Component Traceability In Action 

Dot Peen marking machines are utilized in almost every industrial-goods manufacturing operation, including: 

  • Automotive
  • Oil and Gas (pipes, fittings valves, other)
  • Aerospace
  • Defense
  • Metalworking (general purpose)

Dot Peen Marking 101

While these machines can run in-line and handle large quantities in an automated production environment, most are operated manually using a battery pack to go mobile. 

The best Dot Peen marking machines utilize a fully electric design and that doesn’t require compressed air to operate.  All Technomark Dot Peen marking machines feature an Intelligent Driving Impact (IDI) function that allows for marking on many different materials and finishes. The IDI function automatically adjusts and levels the stylus to the workpiece. Whether the part has a curved, wavy, or complex geometry, the stylus will follow the contour of the marking surface while maintaining a constant depth of high-quality marking throughout. 

When structural integrity is crucial, Dot Peen marking provides a low-stress marking solution that removes no material during the part marking process.

Why Choose Dot Peen Marking

One of the biggest benefits of a Dot Peen Marking Machine is its ability to efficiently produce marks compared to other marking systems. Other benefits of Dot Peen machines include: 

  1. Portability: battery-operated systems are ergonomic and perfect for smaller-scale operations or marking of large, heavy parts that cannot be transported to a fixed location for marking
  2. Versatility: state-of-the-art Dot Peen marking systems are modular and can start with a portable or manual marking system that can later be adapted to a fully automated production line
  3. Ease of use: Dot Peen machines are easy to program and do not require any advanced computing knowledge or technical training. 
  4. Permanency: Dot Peen marking process yields a permanent, indelible mark that can withstand harsh operating environments
  5. Economical: Compared to other marking systems, Dot Peen systems are typically less than $10,000.

Integrating a dot peen marking machine into your production line will improve the productivity and quality of the part-marking process.  

New and exciting dot peen innovations are coming this fall. Be on the lookout for machines that feature: 

  • Wireless connectivity between marking head and control (Network-able devices that are able to communicate to other devices through wireless communications)
  • On-board diagnostic tools to help the operator know when it’s time for scheduled maintenance — protecting your investment.

Direct Part Marking & Deconstructing Data Matrix Codes

, , , ,

Commerce has come a long way from the bartering system. When currency became the acceptable medium of exchange, it only made sense that a better system of marking products was needed. 

The first barcode was created in 1952, but they weren’t put into use in commerce and the transaction process until 1974, when a pack of Wrigley’s gum was scanned in a supermarket in the state of Ohio. 

Barcodes have become widely used and have been upgraded and improved in an ongoing process. From the days when a barcode took up a significant amount of the packaging and contained limited information to today’s Data Matrix codes that are significantly smaller and can hold more data, the barcode development process has been fast and focused on efficiency. 

Here we will focus on Data Matrix codes, their importance, their history, and an in-depth look at:

  1. How they’re generated
  2. How they differ from other marking processes
  3. What industry these are most common in and on which type of materials and parts are they commonly found

Understanding DataMatrix Code

DataMatrix codes are composed of two distinct components: the data and the error correction. The data component is a string of characters that contain information relevant to the product or item that it is associated with. This information can range from production date, to batch code and expiration date.

The error correction component, known as Error Correction Code or ECC, is used to detect any errors in the DataMatrix code, which makes it possible for scanners and other readers to still accurately read and interpret the code even if portions of it have been damaged or altered. The code is also capable of encoding a range of different data types such as numbers, text, URLs, images, and binary data.

This combination of data and error correction makes DataMatrix codes an ideal choice for UID technology in industrial and manufacturing applications. Their small size makes them easy to store while their ability to hold large amounts of data enables them to track complex production processes with greater accuracy than traditional linear bar codes. Furthermore, they can be read quickly, making them suitable for high-speed scanning operations.

DataMatrix codes are two-dimensional symbols made up of square and hexagonal modules arranged in a pattern. They can hold up to 2,335 alphanumeric characters and can be read from any direction.

DataMatrix codes are most commonly used in the automotive industry to track parts and components through the entire production process. They have also been seen in other industries such as aerospace and medical device engineering. In each of these cases, they provide detailed analytics on products throughout their lifespan and enable manufacturers to maintain accurate records of each part or component produced.
The Difference Between DataMatrix Code and QR Code
DataMatrix codes have unique shapes and sizes compared to standard barcodes and QR codes. While typical barcodes and QR codes are rectangular in shape, DataMatrix codes come in both square and circular designs. This makes them easy to distinguish from traditional barcodes and QR codes at a quick glance.

DataMatrix codes also offer better security than other types of industry coding systems due to their increased data capacity and ability to encode binary data. This makes it easier for malicious actors to decipher encoded information with the correct decryption key.

DataMatrix codes have numerous advantages over other types of coding systems. Their increased data capacity, unique shapes and sizes, and ability to encode binary data make them particularly secure against malicious actors attempting to access the encoded information. Their Error Correction Code (ECC) allows them to be scanned even if portions of the code are missing or damaged.

On the other hand, due to their increased complexity compared to standard barcodes and QR codes, DataMatrix codes require more specialized knowledge and technology for both encoding and decoding. This can lead to higher costs associated with the implementation and maintenance of the coding system.

In addition, DataMatrix codes are not as widely used as traditional barcodes and QR codes, which means that they may not be compatible with existing scanning hardware in many locations.

Best Practices for Direct Part Marking

When it comes to Direct Part Marking, proper placement and sizing of DataMatrix codes are essential for accurate scanning. In order to ensure that scanners are able to read the codes quickly and accurately, they should be placed in areas with minimal background interference.

The size of the code should be appropriate for the type of scanner being used – a code that is too small can be difficult to scan accurately. It’s important to make sure that the code is large enough so that when scanned, all of the encoded information can be captured in one pass.

It is also important to consider the durability of the code itself. DataMatrix codes are designed for applications in harsh environments, but it is still important to use a material that will resist damage from abrasion, chemicals, and extreme temperatures.

It’s also important to make sure that any direct part marking ink or other material used can withstand these conditions too. Additionally, proper application of the code is essential for readability – it must be applied correctly and completely for scanners to read it accurately.

Direct Part Marking | Navigating the Options Effectively

Direct part marking is a critical component of manufacturing processes, and it is important to understand the differences between various types of codes, including DataMatrix codes.

It’s essential to ensure the code size and material are appropriate for its intended environment, and that it is properly applied for accurate scanning. With these components in place, DataMatrix codes can provide a reliable means of identification and tracking in harsh environments.
