DROPLET FORMING METHOD FOR MIXED LIQUID AND DROPLET FORMING DEVICE, AND INK JET PRINTING METHOD AND DEVICE, AND INK JET PRINGING ELECTRODE-CARRYING NOZZLE

摘要

The invention provides an ink jet printing method for printing a color image on a printing object by using a plurality of inks, wherein ink nozzles 9a through 9d which house the plurality of inks, respectively, and a dilution nozzle 8 which houses a dilute solution that can dilute the inks are used, the ink is discharged from the ink nozzle 9a by an electrostatic sucking force to form a droplet L on a printing object 4, and then the ink is discharged from the ink nozzle 9b by an electrostatic sucking force and the inks are mixed within the droplet L to form a droplet in an arbitrary additive color. In this case, primary color inks can be accurately mixed within the droplet L.
