Industrial coding comparison
TIJ vs CIJ:
which inkjet fits?
A practical comparison of thermal inkjet and continuous inkjet for variable coding on moving products and packaging.
Two different approaches
Both print variable data.
They do it differently.
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.
TIJCartridge-based, high-resolution
CIJContinuous ink circulation
ApplicationThe deciding factor
01Thermal inkjet characteristics
Where TIJ is strong
Compact equipment
and detailed output.
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.
- High-resolution text, logos, QR and DataMatrix
- Compact printhead and controller options
- No continuously circulating ink system
- Cartridge-based colour or formulation changes on supported platforms
Main constraint
TIJ generally needs a small, consistent print gap, so product presentation and guarding around the head require attention.
02Continuous inkjet characteristics
Where CIJ is strong
Flexible placement
on fast-moving products.
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.
- Small-character codes at high production speeds
- Useful throw distance for irregular or curved products
- Broad specialist ink availability across established platforms
- Common fit for harsh or around-the-clock industrial environments
Operating model
Review fluid consumption, ventilation, servicing, start-up/shutdown and the consequences of extended idle periods.
Comparison factors
Choose on the variables
your line cannot change.
A line trial is the best way to compare the technologies when the decision is close.
Throw distance
CIJ commonly tolerates a larger gap; TIJ benefits from close, stable presentation.
Substrates
Both offer multiple inks, but exact adhesion and resistance require testing.
Maintenance
TIJ renews key components with the cartridge; CIJ has a serviced fluid system.
Environment
Dust, washdown, temperature, ventilation and shift pattern influence the choice.
Lifetime cost
Compare consumables, servicing, downtime, waste, code coverage and support.
Side-by-side view

not universal rules.
Capabilities vary by model and ink. Confirm every critical requirement against the shortlisted equipment.
Operating principleTIJ: on-demand cartridge droplets. CIJ: continuously circulating pressurised ink.
Print qualityTIJ often favoured for high-resolution detail; CIJ strong for robust small-character codes.
Product gapTIJ usually close and controlled; CIJ commonly allows greater throw distance.
ConsumablesTIJ cartridges; CIJ ink, make-up fluid and periodic service items.
Idle operationTIJ can suit intermittent use; CIJ shutdown and restart behaviour depends on system and schedule.
Best decision methodRepresentative product trial at real speed with agreed quality and operating criteria.

Is TIJ cheaper to run than CIJ?+
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.
Which produces better QR and DataMatrix codes?+
TIJ is often selected for high-resolution 2D codes, but either technology must be assessed for module size, contrast, substrate, speed and scanner result.
Which printer is better for curved bottles?+
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.
Can TIJ replace every CIJ application?+
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.
