Every part tells a story.
In manufacturing, that story is written with precision and permanence. From serial numbers to intricate barcodes, part markings ensure every component can be identified, traced, and trusted throughout its lifecycle. But how do you choose the right system to deliver these critical marks?
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.
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.
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.
Data 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.
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.

| Companies, warehouses, factories, stores |
| Pallet cases, crates, totes |
| Medical, manufacturing, transport and IT equipment |
| Loyalty scheme members, doctors at a hospital, library members |
| Automobile parts |
| Medical device |
Beyond GS1, specifications and requirements for each code are presented by the International Organization for Standardization (ISO). For more about how these codes work themselves, and how to create them, you can check out the relevant ISO standard for more detail.
Requirements for Data Matrix codes are specified under the ISO/IEC 16022 international standard; while requirements for QR codes are specified under the ISO/IEC 18004 international standard.
Implementing Data Matrix codes in a manufacturing process can significantly enhance traceability, efficiency, and accuracy. However, to fully leverage the advantages of this technology, it’s crucial to follow best practices tailored to the specific needs of your operations.
Best practices for implementing Data Matrix codes include:
Data Matrix codes have more robust error-correcting features compared to QR codes. They can still be accurately read even when up to 50% of the code is damaged, making them more reliable in harsh environments like manufacturing or logistics. QR codes, on the other hand, lose readability once about 30% of the code is damaged, making them more prone to failure in industrial settings where wear and tear are common.
The cost of implementing QR or Data Matrix codes can vary depending on factors such as the specific hardware and software used, the complexity of the system, and the volume of codes needed. In general, Data Matrix codes may be slightly more expensive to implement due to the specialized equipment required for their reading and writing. However, the long-term benefits of using Data Matrix codes, such as improved traceability and efficiency, can often outweigh the initial costs.
While both QR and Data Matrix codes can be scanned at high speeds, Data Matrix codes often have a slight advantage in terms of scanning accuracy. Their smaller size and denser data encoding make them less prone to misreading, especially in challenging conditions.
Understanding the differences between QR codes and Data Matrix codes, and choosing which is best for your application can get overwhelming. That’s why its important to consult a trusted advisor and partner.

What commonalities do DVD players, checkout lines at the grocery store, and industrial marking machines all share? Lasers.
But alas, not all lasers are the same.
Do you know what L.A.S.E.R. stands for? Light Amplification by Stimulated Emission of Radiation. In other words, it’s a highly concentrated beam of light. Lasers consist of a:
Laser part marking requires an understanding of both the engraver that will best fit your application requirements and the laser source that will provide the best mark. There are a variety of laser sources, and we will highlight three types, as well as two subtypes, of the best laser-marking technology and outline the best choice for the material you are using and the depth of the mark you require to meet regulatory requirements.
Laser part marking is common in a number of industries because it is effective for long-term part identification and meets the rigorous standards set forth for aerospace, mechanical, and other high-demand industries.
However, each industry has specific needs when it comes to the product, and the potential damage to the product if the wrong laser is used. The equipment you need is part of the process, but from there the laser that is best is the next point to consider.
With that in mind, we can take a look at five of the commonly used lasers and the best use case for each:
CO2 laser marking is a popular laser engraving and marking solution because of its ability to mark non-metallic materials. It’s efficient in marking a variety of non-metals, too, including:
The CO2 laser produces an infrared laser beam and uses CO2 gas as the active medium. The laser is emitted at 10.6 micrometers and features high beam quality, allowing it to focus laser power into a small spot and produce high-quality laser marks. This laser has the longest wavelength, which is located on the invisible infrared spectrum.
This laser is efficient for cutting some materials and for personalizing products. However, this type of laser also requires more maintenance and uses more energy.
Another laser source is fiber laser marking, which also offers the ability to mark non-metallic surfaces with a high degree of accuracy. This laser source utilizes a shorter wavelength than a CO2 laser and uses a fiber optic laser device to emit laser beams at a wavelength of 1.064 micrometers. The wavelength produced is located in the infrared spectrum.
It quickly and accurately produces laser marks on materials such as:
This laser source also offers the ability to be tuned for specific applications with easily adjustable settings.
A fiber laser can also be used for embossing or to add discoloration where desired. The discoloration process with a fiber laser provides a variety of colors and better control simultaneously.
The fiber laser is the most commonly used in the laser marking industry, particularly common in aerospace, metallurgy, automotive, and mechanical applications. It’s useful for all types of metals and has a long lifespan when compared to other lasers.
The YAG laser operates on a wavelength similar to the fiber laser (1.064 micrometers). However, this type of laser has a different structure than a fiber laser and the beam passes through different crystals in order to create the beam.
The YAG laser is ideal for marking metals and plastics in its more widely recognized configuration. However, it can be adjusted to mark more sensitive materials as well.
The green laser, the first subtype of the YAG laser, is the only laser with a wavelength in the visible spectrum. This allows manufacturers to mark many sensitive materials, such as:
The green laser is ideal for these sensitive materials because its wavelength is located near the UV spectrum generates less heat.
The UV laser is another subtype of the YAG laser. Thanks to implanted crystals, it became possible to adjust the wavelength for this laser and utilize others, providing access to the only laser in the invisible ultraviolet spectrum (0.355 micrometers).
The UV laser has the shortest wavelength used in the laser marking field and as such is relied upon for markings on fairly sensitive materials.
This laser also makes it possible to carry out “cold markings” — which means manufacturers can avoid the degradation of parts due to the heat. This laser is used for marking solar panels, electrical components, and other parts that require a refined approach.
Planning production of your next line means a lot of considerations. These include the material you will use and the speed you can expect products to be completed. Meanwhile, several of those factors also influence the choice of laser:
With the variety of materials used in production, it makes sense to prioritize the materials when considering a laser source. For more heat-sensitive materials, it’s important to find the right laser and access one that is easily adjustable.
The Mean Time Between Failures (MTBF) is a guideline of how reliable your laser will be based on its hours of operation. Each laser has a different expectation — and keep in mind these are mean times, not a guaranteed lifespan. Some lasers have a longer MTBF but can fail in a shorter period of time than expected
While the fiber laser has an MTBF of 100,000 hours, CO2 lasers have a significantly shorter MTBF of 30,000 hours. This is a crucial factor to keep in mind while choosing the best option for your production cadence.
Some lasers are singled out for the ability to make deeper marks than others. For certain regulations and standards, the laser with a deeper marking capability would be the preferred choice.
Meanwhile, other materials require a lighter mark that doesn’t cause damage. Therefore, the depth of the mark is a key factor in laser source choice.
Some lasers require more maintenance than others. This means a commitment of more of the budget and possible interference with production timelines if maintenance is required frequently.
Your production timeline is important both for your revenue and to help your clients meet their own projected deadlines. As such, the marking process needs to be completed in a timely manner.
Note: Depending on the material to be marked, the right laser source makes a difference in meeting that timeline and getting behind due to lengthy marking processes. If laser marking isn’t the answer at all, there’s always dot peen marking.
In some industries, the laser will need to be adjusted for separate part lines or stages in the production process. In these cases, it is more cost-effective to find a laser that can be adjusted easily. This better facilitates effective marking on the desired timeline.
With three laser marking types and two subtypes, it should be a reasonable process to narrow down the best laser for an application based on the factors involved. Your production line requires a certain type of mark and you have an expectation of how long that mark will last.
The right laser marking source means faster delivery of products that carry distinct markings to fit your clients’ needs.

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 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:
Disadvantages of utilizing dot peen marking include:
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:
Three main advantages of laser marking are as follows:
Meanwhile, some disadvantages of this marking system include:
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.
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:
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.
Our Part Marking page offers a detailed look at the types of lasers and benefits of each, as well as the benefits of dot peen marking as an alternative. The guide also shares info on the type of mark needed and the materials you are marking during production. Take a look:
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.
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 machines are utilized in almost every industrial-goods manufacturing operation, including:
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.
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:
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:

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:
