Increased Inkjet Printing Frequency From ‘Offset Channel’ Printheads
Abstract:The request for increased print throughput in inkjet printing can be met by increasing the print frequency, while maintaining high ink drop volumes. A modified ink channel geometry, termed ‘offset-channels’ is presented, which combines both, short, stiff channel walls and large channel cross sections, respectively. Features of this printhead are high resonance frequencies of the channel walls, and high ink drop volumes up to the highest print frequencies. A Chevron-type version of the offset-channel actuator allows operating the printhead at low driving voltages.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
