APPARATUS FOR ROLL TO ROLL PRINTING

摘要

PURPOSE: A roll-to-roll printing device is provided to implement micro-jetting of ink through induction of an electrostatic field because a plurality of micro-nozzles are directly connected to rolls. CONSTITUTION: A roll-to-roll printing device comprises a chamber(112), a body(110), and a printing roller part. The chamber is formed inside the body in order to accept a fixed amount of fluid. The body is connected to the chamber and formed with a nozzle on a side for jetting the fluid. On the exterior of the printing roller part, a plurality of droplet injection ink-jet heads(100h) including actuators are arranged. The actuators form an electrostatic field so that the fluid is sprayed through the nozzles.
