  • Publication number: 20190092008
    Abstract: A method of printing onto a surface of a cylinder having radius Rc using a stationary inkjet printhead. The method includes the steps of: rotating the cylinder at an angular velocity ?c of at least ? radians per second; and ejecting ink droplets from the printhead at an ejection velocity in the range of 6 to 20 meters per second. The printhead has a print zone with a width Wp and first and second nozzle rows positioned distances d1 and d2 relative to a centerline of the print zone. The print zone and cylinder fulfil the relationship Wp/Rc?0.2, and the first and second nozzle row ejects ink droplets at times T1 and T2, whereby T1=d1/Rc?; and T2=d2/Rc?c.

  • Publication number: 20190061352
    Abstract: A capper for an inkjet printhead has a perimeter seal for sealing engagement with a capping surface of the printhead. The perimeter seal is formed from an auxetic material having a negative Poisson's ratio. The capper is suitable for capping printheads having capping surfaces containing non-unformities. The capper is especially suitable for capping pagewide inkjet printheads.
