Print detail
TIJ commonly offers strong high-resolution output; assess code need at real speed.
Industrial coding comparison
A practical comparison of thermal inkjet and continuous inkjet for variable coding on moving products and packaging.
Two different approaches
Thermal inkjet fires droplets on demand from a replaceable cartridge. Continuous inkjet circulates pressurised ink through the printer and deflects selected charged droplets towards the product.
Neither technology is universally better. Product distance, surface, speed, code content, environment, maintenance and ownership model determine the stronger fit.
Where TIJ is strong
TIJ is often attractive for sharp text, graphics and 2D codes where products can pass close to the printhead. Cartridge replacement renews the ink-delivery and nozzle components together.
It can suit intermittent operation and packaging environments where a small printhead and straightforward routine maintenance are valued.
TIJ generally needs a small, consistent print gap, so product presentation and guarding around the head require attention.
Where CIJ is strong
CIJ is widely used for small-character coding on fast lines and irregular or curved products. It can often tolerate a larger product-to-printhead distance than TIJ.
The recirculating system requires make-up fluids, filters and planned maintenance, while offering a broad range of specialised industrial ink options.
Review fluid consumption, ventilation, servicing, start-up/shutdown and the consequences of extended idle periods.
Comparison factors
A line trial is the best way to compare the technologies when the decision is close.
TIJ commonly offers strong high-resolution output; assess code need at real speed.
CIJ commonly tolerates a larger gap; TIJ benefits from close, stable presentation.
Both offer multiple inks, but exact adhesion and resistance require testing.
TIJ renews key components with the cartridge; CIJ has a serviced fluid system.
Dust, washdown, temperature, ventilation and shift pattern influence the choice.
Compare consumables, servicing, downtime, waste, code coverage and support.

It depends on print coverage, volume, cartridge price, CIJ fluid use, service, downtime and shift pattern. Compare total cost using the real message and annual production.
TIJ is often selected for high-resolution 2D codes, but either technology must be assessed for module size, contrast, substrate, speed and scanner result.
CIJ can be advantageous where product distance varies because it often supports a larger throw distance. TIJ can work when bottles are guided to maintain a close, repeatable gap.
No. The technologies overlap, but extreme speeds, irregular products, harsh environments, specialised inks or larger throw distances may favour CIJ. Detailed, high-resolution packaging codes may favour TIJ.
