20100053263 | DROPLET DISCHARGE DRAWING APPARATUS, DROPLET DISCHARGE DRAWING METHOD, AND DROPLET DISCHARGE DRAWING PROGRAM - A droplet discharge drawing apparatus of the present invention includes: an ink discharging section for discharging droplets to a plurality of targets of discharge present on a target recording material; a gantry sliding mechanism for relatively moving the ink discharging section with respect to the recording medium; and a pre-oscillation section for causing pre-oscillation of the droplet discharging section. The droplet discharge drawing apparatus further includes a control section supplying, to the pre-oscillation section, a pre-oscillation signal for causing the pre-oscillation of the ink discharging section so that the pre-oscillation is carried out before discharge of a droplet and within a time in which the displacement section moves the droplet discharging section relatively with respect to the target recording material. This provides a droplet discharge drawing apparatus which inhibits an increase in viscosity of the droplet during a time when the droplet discharging section moves so that (i) clogging of a nozzle or the like is prevented and (ii) a droplet made of, for example, ink is discharged at a high precision of landing. | 03-04-2010 |
