Exceptional print quality with PrecisionPlus Technology

+

Widest range of fluids now including UV

+

Flexible & easy integration

500 nozzles in 70mm width

Wide 70mm print swathe for high productivity and less printhead stitching. Native resolution of 180 nozzles per inch providing flexibility for single or multi-pass print

Multiple print orientations

Prints reliably in vertical or horizontal modes, or dynamically on a robot arm

TF Technology recirculation

Xaar’s TF Technology ensures instant prime and startup as well as reliability, ease of use and excellent print quality

Flexible drop sizes

XaarDot provides different drop sizes from greyscale technology to optimise coverage and print quality

XaarGuard

Maximising life, uptime and print quality through nozzle protection

High Laydown Technology

Delivers very high volumes in single pass for coatings and structuring

Ultra High Viscosity

Viscosities of up to 60cP can be jetted, for printing an increased colour gamut, high opacity and special effects or jetting a higher molecular weight materials

Print uniformity & quality

The enhanced actuator gives exception uniform drop formation delivering even colour density across the swathe combined with PrecisionPlus for unprecedented drop placement

Product customisation

Put your own logo / branding onto the printhead to ensure visibility of your brand on the print engine

Other Applications:
This printhead family can also be used to print fluids used in the Advanced Manufacturing and 3D market sectors. The piezo inkjet technology used in these printheads is capable of printing fluids with a range of viscosity, reactivity and conductivity. Xaar can support you in choosing the right printhead for the fluid type and for the application vs. the performance specification and price.

Xaar’s Unique TF Technology

Dynamic printing in any orientation

Flexible ink supply system options

No recirculation

A simple ink supply can be used for the simplest integration.

Ink flows to the channels and is ejected through the nozzles with no ink recirculation.

Pulsed TF Technology re-circulation

Ink is recirculated only when the printhead is not jetting

Delivering benefits in reliability while maintaining simplicity of implementation. During non-jetting periods the ink is recirculated past the back of the nozzles.

Example. During the space between boxes on the conveyor or when you activate the cleaning cycle.

Full TF Technology recirculation

Continuous ink flow at a high rate directly past the back of the nozzle during drop ejection.

Air bubbles and unwanted particles present in the fluid are carried away.

Improves reliability in the harshest industrial environments.
