ABSTRACT:
The invention concerns a method for increasing the number of ink drops in an ink drop jet of a continuously operating inkjet printer, in which the ink drops of at least two separately produced ink drop jets are combined into an ink drop jet. In one example embodiment this is done so that the combined ink drop jet includes the ink drops of the respective separate ink drop jets. The invention also concerns a device for production of an ink drop jet of a continuously operating inkjet printer, which includes at least two pressure chambers for generation of a separate ink drop jet with electrically charged ink drops and an electrode arrangement wherein the separate ink drop jets can be combined into a singe ink drop jet.
