OUTSTANDING IMAGE QUALITY WITHOUT
COMPROMISE
• Designed for the indoor & outdoor graphics
market
• Excellent print performance
• Consistent and reliable operation
• Easy to integrate and scalable.
The highly productive Xaar Proton is a wide-swathe,
high-resolution binary printhead.
The latest ‘chevron’ actuator technology delivers
consistent and reliable operation for the indoor &
outdoor graphics markets.
Printer manufacturers will find a host of features that
make this printhead easy to integrate, reducing set up
times and ensuring maximum profitability. End users
will achieve highest return on investment through ease
of use and high productivity combined with excellent
print performance.
Using the latest piezoelectric inkjet technology it
provides excellent print performance enabling you to
print even better quality without compromising on
speed.
Xaar Tec hnology
Xaar is a world leader in the development and
manufacture of piezoelectric drop-on-demand
inkjet technologies. Its latest shear mode
shared wall technology uses a ‘chevron’
actuator which combines 2 layers of the PZT
material to give a structure that requires only
24V to drive it and therefore consumes even
less power and ensures even higher drop
formation consistency. This coupled with
higher firing frequencies, smaller drops and
individually lasered nozzles leads to a highly
productive printhead with premium print
performance and a long life.
Applications
The Xaar Proton has been designed to
produce outstanding print quality for the
indoor and outdoor graphics market –
rapidly and consistently. Delivering a 35pl
drop ensures sufficient resolution to meet
today’s demands of the graphics and
signage markets and with a 53.7mm
swathe, high-speed multi-pass printing is
a reality.
Inks and Fluids
Xaar actively partners with a range of ink
manufacturers to develop high-quality ink
solutions for its printheads. The Xaar
Proton is constructed to be compatible
with a range of solvent-based inks.

Xaar’s ENABLING technology
OEM’s can take advantage of the features within
the Xaar Proton to enable fast time-to-market and
minimal development costs. This is achieved by
utilising the on-board electronics that offer many
additional features within the printhead itself instead
of the OEM having to develop their own. This
includes on-board waveform storage and
temperature compensation for example.
Other features include:
• Lockable fluid and electrical connectors - make
it easier and quicker to install, remove and
replace printheads when necessary as well as
ensuring reliable fluid and electrical connection
necessary in industrial printers
• Recessed nozzle plate - is designed to prevent
nozzle-plate damage in the event of a media
crash thereby extending the working life of the
printhead
• Simple fluid path - enables fast and reliable
filling ensuring the printhead is always primed
and ready for operation
• In-line filter - which protects the printhead
thereby extending its working life
• Metal back plate - offers simple mounting plus
the option to apply heat to allow for a wider
range of fluids
• Low drive voltage – the single 24V power supply
allows OEMs the lowest cost of integration.
Overall the Xaar Proton offers a simple, easy
integration path for wide and grand-format printer
manufacturers who want the best combination of
print performance and productivity.
