Inkjet aspires to be the dominant technology in commercial printing. Current and future uses of inkjet in that printing market demand faster print frequencies and higher print speeds to achieve the desired throughput and productivity. Xaar is developing a range of technologies that enable high speed printing and exploring the limits of their suitability in specific applications.

One such technology uses recent advances in the exploitation of shared wall technology to enable the development of single cycle nozzle operation for shared wall devices. The elimination of the 3-cycle firing mechanism facilitates a threefold increase in print speed without a trade off in image quality. This print performance is a result of continued understanding of fundamental mechanisms associated with complete drop ejection. Printhead evaluation has shown thermal management, drop placement and reliability can meet the requirements with the new productivities.

An alternative technology uses standard printheads stacked together inline, printing in 3-cycle firing mode. For this configuration the print image is split accordingly between the printheads and thus the print speed can be increased by a factor equal to the number of printheads. Printhead stacking has been explored by increasing the stack up to seven printheads on an offset-press. The effectiveness of this configuration is evaluated as a function of firing frequency and substrate feed rate, offering important information that needs to be considered for high frequency integrated system design.

More about this publication?
  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
