Increased Inkjet Printing Frequency From ‘Offset Channel’ Printheads
  DOI :  10.2352/ISSN.2169-4451.2003.19.1.art00066_1  Published OnlineJanuary 2003

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.
