  • Patent number: 9630398
    Abstract: An assembly of at least one object and a machine for printing the object, the object having an outer surface substantially of revolution around an axis, and a handle. The machine includes four ink jet printheads, at least one object holder and a support on which the object holder is fastened. An actuator moves the support relative to the printheads in at least four print configurations, and the object holder drives rotation of the object around the axis in each printing configuration. A commander commands the object holder to rotate the object relative to the corresponding printhead around the axis from an initial printing position, in which the handle is located near the printhead on one side of the median plane of the printhead, to a final printing position, in which the handle is situated near the printhead on the other side of the median plane.
