METHOD AND DEVICE FOR FORMING LIQUID DROP OF MIXED LIQUID, INK JET PRINTING METHOD AND PRINTER, AND NOZZLE WITH ELECTRODE FOR INK JET PRINTING

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for forming a liquid drop of mixed liquid in which liquids being ejected independently from respective nozzles can be mixed surely on an liquid drop forming matter, and to provide ink jet printing method and printer, and a nozzle with an electrode for ink jet printing.;SOLUTION: In the ink jet printing method for printing a color image on a printing matter using a plurality of inks, ink nozzles 9a-9d for containing the plurality of inks, respectively, and a nozzle 8 for containing a dilute liquid of these inks are used. After a liquid drop L is formed on the printing matter 4 by ejecting ink from the ink nozzle 9a through electrostatic attraction, ink is ejecting from the ink nozzle 9b through electrostatic attraction and then inks are mixed in the liquid drop L to form a liquid drop exhibiting an arbitrary intermediate color. In this regard, primary color inks can be mixed surely in the liquid drop L.;COPYRIGHT: (C)2004,JPO
