A combination of novel piezoelectric inkjet print head technologies such as greyscale, shared wall and genuine throughflow have led to the development of inkjet print heads able to deliver the quality and reliability demanded by modern single-pass printing applications. While shared wall technology can provide benefits such as acoustic firing and reduced drive voltage, there are limitations in the final achievable firing frequency, dictated by a 3-cycle firing pattern (active-idle-idle). As a result the print speed is restricted.Recent advances in the exploitation of the base shared wall technology have allowed the development of single cycle nozzle operation (always active) for shared wall devices. This has yielded approximately a three-fold increase in firing frequency and hence the three-fold increase in print speed from a print head of similar footprint. Such dramatic improvement has been possible by deeper understanding of the events involved in the complete drop ejection cycle combined with clever rearrangement and overlapping of the events for arrays of nozzles working in synchronization.Three implementations of a single cycle operation have been explored, some which impose imaging limitations and others which use technically complex solutions but imaging capabilities are unhindered. Commercialization of these technology variants is currently underway with some already deployed in end user production environments.
