  • Process and device for rotating an ink container used in tampon printing
    Patent number: 5669301
    Abstract: A printing block is inked with a container containing printing ink, and printing formats or partial images are transferred to workpieces with a tampon. An edge of the container, which edge lies on the printing block, is rotated on the printing block around a vertical axis during a relative movement between the container and the printing block. As a result, the printing block can be used longer, and a clean print is guaranteed for a longer time in the case of abrasive printing inks.
