Overview

The Xaar Proton printhead is a premium quality, wide-swathe (53.7 mm) printhead which delivers outstandin​g print quality in two drop volume options.

The binary 35 and 60 picolitres variants deliver the best combination of throughput and print quality for a range of applications, including wide-format graphics and coding marking. The Xaar Proton delivers excellent and consistent print performance enabling users to achieve high print quality without compromising on speed. ​​

Features

Outstanding print quality
  • Two native drop volume options deliver the best combination of throughput and print quality for a range of applications
  • Individually lasered nozzles for better nozzle uniformity and more accurate drop placement and formation
  • Internal temperature sensing and autom​atic voltage compensation ensure high reliability and consistent drop volume
  • Waveforms for Xaar-approved inks are tuned for optimised jetting performance.
E​asy integration
  • ​Intelligent on-board electronics enable simple integration and installation
  • Luer-lockable ink fittings and lockable electrical connections for easy, accurate and secure installation
  • Two ink ports offer a range of ink supply configurations for ease of priming and maintenance​.
​High productivity
  • High firing frequency, delivering fast and useable linear speeds
  • Can deliver throughput equivalent to a printhead with a larger nozzle count.
La​​test technology​
  • Latest nozzle processing techniques deliver better print quality and longer throw distances
  • Chevron actuator design gives high efficiency and consistent drop formation, resulting in outstanding print quality
  • Printhead stores multiple waveforms for different fluid types, applications and print characteristics
  • Low energy drop ejection enables efficient drop formation with high drop placement accuracy.
Low cost of ownership
  • Robust printhead casing protects against costly accidental mechanical, electrical and chemical damage
  • Integrated internal filter increases product lifetime by protecting actuator and nozzles from contamination
  • Recessed nozzle plate protects against printhead damage caused by media crash or other mechanical impact​.​​​​
