Title:
INK DISCHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/077335
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide an ink discharging system that can cause printing speed to be more rapid than conventional printing speeds. To solve the problem, the present invention is characterized in that the control unit of the ink discharging system (20) causes ink (20a) housed in a recording head (30) to be electrostatically charged by means of a flight assistance device (50), causes ink droplets (20b) of the ink (20a) electrostatically charged by means of the flight assistance device (50) to be discharged from a nozzle (31a) by means of an ink extrusion device (40), and causes the flight of the ink droplets (20b) discharged from the nozzle (31a) by means of the ink extrusion device (40) to be assisted by the flight assistance device (50) by means of electrostatic force. The present invention is further characterized in that the pressure that the ink extrusion device (40) applies to the ink (20a) is a pressure such that ink droplets (20b) can be discharged from the nozzle (31a) by only the ink extrusion device (40) among the ink extrusion device (40) and the flight assistance device (50), and is a pressure such that the ink droplets (20b) are discharged from the nozzle (31a) at less than the smallest size that can reach a recording medium (90) against air resistance in the case that the flight assistance resulting from the flight assistance device (50) is absent.
