  • Publication number: 20110074859
    Abstract: 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.
