INK MIXING SYSTEM, HIGH-SPEED DIGITAL INK JET PRINTING APPARATUS USING SAME, AND HIGH-SPEED DIGITAL INK JET PRINTING METHOD USING SAME

摘要

The present invention provides an ink mixing system, a high-speed digital ink jet printing apparatus using same, and a high-speed digital ink jet printing method using same, the apparatus comprising: a material supplying unit for supplying a material to be printed; a front-surface printing unit positioned above the front surface of the material to be printed, and for printing, by means of ink jet printing, the front surface of the material to be printed, which is being transferred by means of the material supply unit, by means of an ink mixing system; a rear-surface printing unit positioned below the rear surface of the material to be printed, and for printing, by means of ink jet printing, the rear surface of the material to be printed by means of the ink mixing system; and a drying unit for drying the printed material which has been printed by means of the front-surface printing unit and rear-surface printing unit. The ink mixing system comprises: a plurality of sources for supplying a plurality of liquid materials comprising an ink of at least one color; an ink mixing unit for receiving the supply of the plurality of liquid materials from the plurality of sources and mixing the received liquid materials; and a printer head which has a plurality of nozzles for receiving the liquid materials from the ink mixing unit and spraying same on an object. Therefore, the present invention has a compact structure and thus occupies a minimum space. Also, the present invention minimizes color errors and enables quick and various color tests by means of digitally mixing inks. And the present invention does not generate waste dyes and thus enables water pollution and air pollution reduction.
