摘要

PROBLEM TO BE SOLVED: To provide a varnish coating device for a two-piece can for preventing the loss of a sense of the gray level of a printed part. SOLUTION: An applicator roll 19 is coated with a varnish by an anilox roll 18, and a two-piece can W immediately after coating an ink to a mandrel 31 is rotatably held in a circumferential direction. A disc 33 to be driven having a smaller diameter than that of the can W and rotated integrally with the can W is rotatably driven by a drive disc 32 having a larger diameter than that of the roll 19 and rotated integrally with the roll 19 and the body of the can W is coated with a varnish while slipping the body of the can W with the close contact surface of the applicator roll.
