Abstract

The invention discloses a gravure printing apparatus which comprises a gravure cylinder for printing patterns, aligning marks and referential lines onto a print substrate, a driving unit supporting and rotating both ends of the gravure cylinder, a pressurizing cylinder facing the gravure cylinder maintaining the print substrate therebetween and pressing the print substrate, a sensor unit formed at one side of the pressurizing cylinder to sense the aligning marks and referential lines, and a control unit which controls the gravure cylinder according to the error of the aligning marks and referential lines sensed by the sensor unit. The gravure cylinder allows sensing and calibrating pattern printing state on a real-time basis, thereby improving the pattern superimposing accuracy of the printing substrate. The gravure cylinder drives the gravure cylinder through a non-contact bearing to calibrate micro-flow of printing errors and retain optimal printing pressure, thereby improving printing quality and uniformity.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of Korean Patent Application Serial No. 10-2011-0134529, filed Dec. 14, 2011, titled "Gravure Printing Apparatus (Gravure Printing Apparatus)", which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a gravure printing apparatus, and more particularly, to a gravure printing apparatus capable of continuously printing electrode patterns on a printing sheet. Background technique [0004] Recently, techniques for realizing small and light electronic products and electronic parts used for the electronic products have been attracting more and more attention. For this reason, techniques for increasing substrate wiring density and reducing the size and weight of individual parts or modules are urgently needed. In order to meet this demand, techniques for manufacturing new parts have been proposed. [0005] In the process of manufactur...
