The present invention provides a droplet jetting apparatus which jets fluid in a droplet shape. The apparatus includes a main body (), which has a chamber () for containing fluid. The main body further has at least one nozzle () which communicates with the chamber and jets a droplet onto a printable matter, and a first electrode () which is formed on the inner surface of at least one selected from between the nozzle and the chamber by patterning treatment to make electrical contact with the fluid. The apparatus further includes a second electrode (), which is provided between the nozzle and the printable matter and has a through hole, through which the droplet is jetted from the nozzle onto the printable matter, a power supply () which supplies a voltage applied between the first electrode and the second electrode, and a control unit () which controls the power supply.

Disclosed are a roll-to-roll printing system and method in which a large number of micro-nozzles are formed directly in a printing roll, and thus ink supplied to the central portion of the roll can be formed into micro-inkjets by inducing an electrostatic field, and furthermore, as a result of the formation of the micro-inkjets, a micro-sized pattern significantly smaller than that achievable by a prior pattern formation method can be printed on a print medium, and in addition, the relative speed of the print medium relative to the roll can be maintained at a speed close to '0' so as to improve the resolution, integration density and precision of the printed pattern. According to the present invention, a large amount of micro-nozzles are formed directly in a printing roll, and thus ink supplied to the central portion of the roll can be formed into micro-inkjets by inducing an electrostatic field.
