Paper: Inkjet and thermal transfer printing are used for QR codes on paper products. They provide fast access to information and verify authenticity.

QR codes improve products by providing information, security, and user interaction options.

Why Choose QR Code Laser Engraving Machine?

Laser marking of QR codes offers several advantages, making it a preferred choice in various industries:

Precision and Clarity: Laser marking ensures high-resolution QR codes, crucial for accurate scanning and readability.

Durability: The markings are resistant to fading, wear, and environmental factors, ensuring longevity of the information.

Versatility: Suitable for a wide range of materials, including metals, plastics, and more.

Speed and Efficiency: Laser marking is faster than many traditional methods, enhancing productivity.

Eco-Friendly: It’s a non-contact process, producing less waste and requiring no consumables like ink.

Cost-Effective in the Long Run: Laser marking is cost-effective with low maintenance and operational costs, despite the initial investment.

How to Choose a QR Code Marking Machine?

Selecting the ideal QR code marking machine involves understanding different marking methods and the materials they suit best. Here’s a simplified guide:

Understanding Different Methods

When selecting a QR code marking machine, understanding the various methods available for marking on metal surfaces is crucial:

Laser Engraving: This technique uses laser etching technology to directly etch QR codes into the metal surface. Ideal for creating high-precision QR codes on metal, it requires specialized laser equipment and expertise. This method stands out for its precision and permanence but involves a significant investment in specialized laser equipment.

Coding: This method employs coding equipment to print the QR code onto the metal surface. Suitable for larger metal surfaces, coding allows for fast and visible QR code printing. A viable option for applications where speed is a priority and detailed precision is less critical.

Etching: Chemical etching is a process where a template is used to etch a QR code onto metal using a chemical solution. This method makes a QR code for metal surfaces that like a traditional approach and find it helpful.

It is helpful because people can easily scan and access it. The QR code provides information or links to relevant content. This method is good for metal surfaces that may not work with other identification or labeling methods.

Printing: Utilizing special metallic or conductive inks, this method prints the QR code on the metal surface. It’s appropriate for flat metal surfaces and can yield clearer QR code printing. This method is beneficial where the application allows for the use of inks and requires a less permanent solution.

In summary, while other QR code marking methods serve specific purposes, they typically lack in precision, efficiency, or durability. Laser marking is a good option because it’s high-quality, efficient, and cost-effective, despite the initial investment. This makes it a favored method across various industries.

However, with numerous types of laser marking machines available, choosing the right one can be challenging. For guidance on selecting the most suitable laser marking machine for your needs, continue reading the following guide.

Selection of Laser QR Code Engraver According to Material

When choosing a QR code marking machine, the foremost consideration is its compatibility with the material you need to mark:

For Metal: Laser marking machines are the most effective for metals. Inkjet, silkscreen, and manual engraving are not clear or durable enough for QR codes on metal surfaces. These older methods could produce codes that can be easily wiped off or inadequately imprinted. A laser machine can engrave serial numbers, QR codes, and images accurately and permanently, solving these problems.

For Wood: If your objective is to mark QR codes on wooden materials, a carbon dioxide (CO2) laser marking machine is the ideal choice. This type of laser is well-suited for wood, providing clear and lasting engravings without damaging the material.

For Plastics: For marking QR codes on plastics, like product packaging or electronic device casings, use a UV laser marking machine. UV lasers are good at working with different types of plastic, providing a gentle process and long-lasting markings.


QR codes are important for connecting physical products to digital data, benefiting industries like retail and manufacturing. The key to leveraging their full potential lies in precise and durable marking.
