Xaar’s recirculation technology delivers the widest window of operation for inkjet printing

  • Date 23 Nov 2020

The results of a series of lab experiments demonstrate why Xaar’s TF Technology ink recirculation, invented some years ago, still sets the benchmark for industrial inkjet recirculation techniques today to deliver a wider window of operation for users.

Presented in Xaar’s new white paper subtitled ‘What goes around, comes around’, the research compares Xaar’s TF Technology ink recirculation with alternative ink recirculation techniques used by most other printhead manufacturers.

Whilst ink recirculation is now commonplace, the white paper clearly shows that all technologies are not equal. A printhead’s architecture determines how well ink recirculation is implemented and therefore influences the degree to which the method delivers benefits across today’s wide range of printing and jetting applications. 

TF Technology is a key building block in Xaar’s recently announced ImagineX bulk platform which will power the next 30 years of innovation in inkjet capabilities and printhead launches.

Together with the unique Hybrid Side Shooter printhead architecture, Xaar’s TF Technology enables ink or other fluids to flow directly past the back of the nozzle during drop ejection at very high flow rates.

This ensures the nozzles are continuously primed, keeping the printhead operational and the nozzles firing and – with the ink in constant motion – prevents sedimentation and nozzle blocking, particularly in heavily pigmented inks. Any air bubbles and unwanted particles in the ink are also carried away, improving reliability, even in the harshest industrial environment.
