Both technologies play a crucial role in product traceability, regulatory compliance, and ensuring clear, readable codes across various substrates.
For example, food and beverage industries often prefer CIJ printers due to their ability to print on flexible packaging at high speeds, while the pharmaceutical industry frequently uses TIJ for high-resolution batch codes and expiration dates on cartons or blister packs. Meanwhile, laser marking is widely adopted in aerospace and automotive sectors for permanent, tamper-proof identification.
Understanding these differences helps you determine which technology aligns best with your business requirements. Still, what advantages and drawbacks follow from both choices? Let’s examine the details below so you might choose the right one!
Inkjet Printing
This printing technique applies tiny ink droplets onto substrates such as paper, plastic, or metal to produce clear text and images with high precision. The designs are formed as ink is ejected from microscopic nozzles in the printhead, enabling highly precise and consistent coding.
When it works, the printhead goes over the substrate, repeatedly dotting it with thousands of tiny ink drops. Moreover, inkjet printers are often categorized into two primary types: continuous and thermal (CIJ and TIJ).
CIJ printers are commonly used in continuous, high-speed production due to their ability to print on various surfaces with fast-drying ink, while TIJ printers are favored in lower-speed applications that require high-resolution printing. While CIJ printers are commonly utilized in continuous, high-speed production due to their ability to print on various surfaces with quick-drying ink, TIJ printers are favored in lower-speed applications where high-resolution printing is essential, such as for barcodes and QR codes. This makes inkjet technology highly adaptable for industries with frequent product changes, offering quick setup and seamless integration into existing production lines.
Now, let’s take a closer look at the advantages and drawbacks of inkjet printing:
Advantages of Inkjet Printing
Inkjet technology has remained a top choice for both consumer and industrial applications due to several key advantages, including:
Cost-Effective Initial Investment
One of its primary benefits is the relatively low upfront cost, making it accessible for businesses of all sizes. Whatever the size of your company, small or large, this system provides a reasonably priced starting point for your coding and marking requirements.
Versatility in Material Compatibility
Inkjet printers can print on a wide range of materials paper, cardboard, plastics, glass, and metal making them highly flexible for companies that work with multiple substrates.
High-Resolution Printing
Modern CIJ and TIJ printers achieve excellent resolution, making them suitable for printing barcodes, QR codes, small text, and detailed graphics.
While TIJ is well-known for its high resolution, making it ideal for printing small barcodes and crisp text, CIJ is better suited for high-speed operations where print quality is less critical than speed and durability.
This level of clarity ensures accurate product identification across various industries. High-resolution output is especially crucial for industries that must meet strict traceability standards, such as pharmaceuticals, food packaging, and electronics.
Wide Color
Inkjet systems can produce vibrant colors, which is valuable for applications requiring color coding or high-quality graphic printing.

Disadvantages of Inkjet Printing
Like any printing method, inkjet technology also comes with limitations that businesses should evaluate before choosing it:
Slower Printing Speeds
CIJ and TIJ printers are generally slower than laser systems, especially when producing high-quality images or handling large production volumes. Laser marking is often viewed as more sustainable because it does not require consumables such as ink or solvents. Meanwhile, CIJ printers require ongoing ink and solvent usage, which can increase environmental impact and long-term costs. This can be a challenge for businesses that rely on high-speed, continuous production lines.
Maintenance Requirements
Inkjet printers require routine maintenance such as preventing ink from drying, cleaning nozzles, and ensuring the printhead remains unblocked to maintain consistent performance.
Higher Long-Term Costs
While ink cartridges and solvents may seem affordable initially, their recurring use can lead to higher long-term expenses, especially in high-volume operations. This is why many businesses evaluate not only the purchase price but also total cost of ownership (TCO), including consumables, maintenance frequency, and downtime.
Laser Marking
Now, let’s move on to laser marking a method that uses a focused beam of light to create permanent marks on a wide range of materials.
The process works by altering the material’s surface through discoloration, engraving, or removing a thin layer to create a clear and permanent mark. Laser marking produces high-contrast, durable marks ranging from simple alphanumeric codes to complex logos and graphics.
This technology is particularly advantageous for industries that demand permanent and tamper-proof markings, such as pharmaceuticals, aerospace, and medical devices. By providing high precision and durability, laser marking ensures compliance with stringent regulatory standards.
The most common laser systems include fiber lasers, CO₂ lasers, and UV lasers each designed for different materials and application needs. This flexibility allows manufacturers to choose a laser system that aligns with their production requirements, material types, and long-term efficiency goals. Here are the general benefits and disadvantages:
Advantages of Laser Marking
Usually, this technology is favored in industries where durability and precision are needed due to these reasons:
