ROLL-TO-ROLL PRINTING DEVICE IN WHICH THE ACCURACY OF PRINTING PATTERNS IS IMPROVED BY CONTROLLING THE TENSION OF A PATTERN MASK

摘要

PURPOSE: A roll-to-roll printing device in which the accuracy of printing patterns is improved is provided to regularly maintain the tension of a pattern mask with a tension controlling member, thereby forming precise printing patterns on a printing object.;CONSTITUTION: A roll-to-roll printing device in which the accuracy of printing patterns is improved comprises n numbers of support rollers(100), a pattern mask(200), a driving unit, a transferring unit(300), a printing unit(400), and a tension regulating member. The support rollers are arranged to form a n square shape. The pattern mask comprises a plurality of pattern unit formed by penetrating inner and outer surfaces and is arranged in a form connecting each support roller each other. The driving unit circulates the pattern mask. The transferring unit comprises an unwinder(310), a rewinder(320), and a backup roller of a printing object(10). The backup rollers are arranged in between the two support rollers arranged adjacently to each other and in an outer side of the pattern mask, thereby supporting the printing object transferring to the rewinder from the unwinder. The printing unit discharges ink toward the printing object being supported to the backup roller.;COPYRIGHT KIPO 2013
