TF Technology

TF Technology is unique to Xaar and is the best ink recirculation technology available. Other manufacturers offer ink "recirculation" but the methods they use cannot deliver the same high levels of reliability and print quality.

Benefits of TF Technology

Unrivalled reliability
  • TF Technology together with the unique Hybrid Side Shooter architecture enables ink or other fluids in the printhead to flow directly past the back of the nozzle during drop ejection, at very high flow rates
  • The highest flow rate is necessary to ensure the nozzles are continuously primed, keeping the printhead operational and the nozzles firing
  • The ink or fluid is in constant motion, preventing sedimentation and nozzle blocking, particularly in heavily pigmented inks
  • Air bubbles and unwanted particles in the ink are carried away, radically improving reliability, even in the harshest industrial environment.
Outstanding print quality
  • TF Technology is a technically superior and unique solution that minimises temperature variation across the printhead as heat is removed directly from within the actuator channels virtually eliminating print density variations
  • Ink viscosity is also controlled like the temperature, delivering uniform printing across the swathe and throughout the print job.
Low cost of ownership
  • Printheads with nozzles working to their full potential are essential for single-pass industrial printing.
  • TF Technology combined with Xaar Hybrid Side Shooter architecture delivers a significant step forward in running inkjet systems reliably for a full shift with minimal maintenance. Running costs are lower because downtime and ink wastage are reduced.
Increased production uptime
  • Instant start up in the mornings and at the start of shifts due to nozzles being constantly primed
  • Quick recovery of the printhead (for example following mechanical shock from media crash) means only one print would be lost and there is no need to stop the production line.

TF Technology in Pulsed mode
  • In some printheads, TF Technology can also be set to operate in Pulsed mode – ink is recirculated when the printhead is not jetting.
  • This allows ink recirculation to be implemented with the minimum of complexity and cost but still improves reliability, enabling nozzle self-recovery, extending maintenance cycles and eliminating air bubbles.

Tuned Actuator Manufacturing

Actuator performance in each printhead is optimised with Xaar’s Tuned Actuator Manufacturing. This process ensures full scalability with a simple and quick set up, streamlining printhead replacement, and achieves consistent print quality across long print bars with multiple printheads, at different greyscale levels.


The Xaar 2001+ family of printheads incorporates XaarSMART technology which reports ink temperature and printhead status in real time so that printer performance can be easily adjusted to deliver consistent print quality throughout a production run.



AcuDrp Technology delivers a number of advantages unique to Xaar including dynamic sub drop tuning for every nozzle in the printhead by waveform and voltage. This helps minimise drop volume and drop speed variation across the printhead, and from printhead to printhead. Therefore banding and colour density variations are minimised and changes in nozzle performance over time are managed effectively. Cold switching ensures heat generation within the printhead is minimised avoiding any impact on printing performance from associated fluid viscosity changes.


High Laydown Technology

Xaar’s High Laydown Technology enables a range of new applications, thanks to its ability to deposit large quantities of fluid in each pass.

For packaging, labels and commercial print, it is capable of printing very high levels of UV inks or high build varnish in a single pass for tactile embellishments. High Laydown Technology satisfies dimension specifications for printing Braille and complies with European standards for tactile warning triangles on labels, without the complexity of screen printing.

High Laydown Technology delivers unprecedented ink discharge rates for gloss and adhesive effects on ceramic tiles, so that effects can be printed at high line speeds.

For additive manufacturing applications, High Laydown Technology offers increased printing productivity which significantly accelerates build rate for parts and the ability to print a broader range of fluids including higher viscosity materials; this ultimately results in tougher 3D printed parts than those printed with standard inkjet technology.



Xaar offers a wide variety of printheads which cover 3 different drop configurations or three different modes of drop formation. Xaar’s customers, therefore, have the flexibility to choose the right printhead for the application. XaarDOT (Xaar Drop Optimisation Technology) encompasses a range of drop formation options, each with specific features. In a variable drop printhead, XaarDOT is incredibly flexible in giving customers the choice of what drop size or sizes to use for a job, both in terms of image quality and substrate flexibility. The drop size determines the image resolution and actual dots-per-inch (dpi). By tuning the options, printer manufacturers can design the printer to produce small drops for high quality photographic results for close-up viewing or larger droplets for high speed coverage on billboards or other signage. The choice really is yours – and the range of drop sizes means you can manage dot gain to enable printing on a wide variety of media from glossy paper to other materials, such as card, vinyl etc.
