If you’re responsible for production decisions, you’ve likely weighed this question. Both technologies are proven and widely used — but they solve different problems. Here’s how to think about it.
The Core Difference
Laser marking uses light to permanently alter a surface. No ink, no consumables. With laser, the mark becomes part of the material itself. Meanwhile, inkjet printing deposits ink onto a surface: fast, flexible, and easy to update. That single distinction drives most of the trade-offs between the two.
Laser Marking: Built to Last
Laser marking may be the solution if durability takes priority. With laser, the result is a mark that cannot rub off, wash away, or fade, enduring through the full life of the product.
This makes laser the right call when permanence is non-negotiable: serial numbers, part IDs, traceability codes on metals and plastics, and any application where marks need to hold up against abrasion, chemicals, or harsh handling. In regulated industries, often this permanent identification isn’t simply a nicety; it’s mandatory.
One practical advantage is the laser’s simplicity of maintenance and reduced ongoing operating costs, requiring no inks or solvents. The trade-off is a higher upfront investment, plus added safety precautions which could add complexities to your lines’ configuration and staff training requirements.
Inkjet Printing: Speed and Flexibility
Inkjet systems apply ink to the product surface in precise, controlled droplets. They’re fast to deploy, easy to reconfigure, and compatible with a wide range of materials and packaging formats — which is why they remain one of the most common marking technologies in manufacturing.
REA JET offers distinct inkjet technologies, namely TIJ (Thermal Inkjet) which uses cartridge-based ink to produce sharp, high-resolution prints and CIJ (Continuous Inkjet) which generates a continuous stream of droplets directed precisely onto the surface. Designed for applications on smooth, absorbent and non-absorbent surfaces, TIJ works well for cartons, labels and paper-based packaging. And, using the streamlined HP cartridge technology where every cartridge swap includes a fresh print head, you eliminate the need for cleaning or service downtime.
Meanwhile, CIJ systems are particularly effective at printing small characters at high-speed lines. The choice for many Canadian manufacturers in the food, automotive, CPG, and pharmaceutical sectors, the REA JET SC 2.0 prints with precision accuracy on curved or irregular surfaces like bottles, cables or blister packs.
The flexibility here is real: codes can be updated instantly, the systems handle a broad range of substrates, and integration into existing lines is straightforward. The ongoing cost to account for is consumables — inks, solvents, and regular printhead maintenance — so total cost of ownership matters when comparing options.
Looking for laser-like permanence without the high cost?
REA JET’s Thermal Inkjet (TIJ) technology, combined with our extensive ink portfolio, delivers durable, high-performance marking across a wide range of substrates.
Our metal etching inks enable permanent marking by chemically bonding with the surface, creating long-lasting, wear-resistant codes ideal for harsh environments. Plus, our UV-curable inks provide fast-curing, high-contrast marks on many materials, offering excellent durability and flexibility for demanding production lines. You can also enhance product security with fluorescent inks, enabling covert marking for traceability and anti-counterfeiting applications.
How to Choose
Most decisions come down to three questions: How permanent does the mark need to be? What material are you marking? And how often do codes change?
If the mark needs to survive the product’s entire lifecycle, laser is the stronger fit. If you’re working with packaging, flexible substrates, or formats where batch codes and expiry dates update frequently, inkjet will serve you better.
In many facilities, both technologies coexist. It is not uncommon to see the same plant using laser marking for permanent product identification, combined with inkjet printing for variable packaging codes and expiration dates.
