GRAVURE PRINTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a gravure printing apparatus which prevents defectiveness from occurring by improving the reliability of a product by separating a pressure moving roll from a gravure roll and bringing the pressure moving roll into contact with the gravure roll according to the presence or absence of a defect on a printing sheet.

SOLUTION: The gravure printing apparatus includes: the gravure roll 10 to peripheral surface of which conductive paste is applied and which prints an electrode pattern on the printing sheet 70 moving at a high speed; the pressure moving roll 20 which is arranged oppositely to the gravure roll 10 with the printing sheet 70 as a medium and which applies a pressure bonding force so that the printing sheet 70 is attached to the gravure roll 10; a defect sensing means 30 which senses the defect of the printing sheet 70 before the electrode pattern is printed on the printing sheet 70 through the gravure roll 10 and the pressure moving roll 20; and a separating means 40 which separates the pressure moving roll 20 from the gravure roll 10 and which brings the pressure moving roll 20 into contact with the gravure roll 10 so as to pass the defect part of the printing sheet 70 according to a signal which is transmitted from the defect sensing means 30.
