WEB-FED GRAVURE ROTARY PRESS WITH COLOR DENSITY DIFFERENCE COMPENSATION MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a web-fed gravure rotary press that can compensate a color density difference (bilateral difference) in a width direction of a printing object.SOLUTION: A web-fed gravure rotary press 10 includes: an inking roller 20 that maintains a supplied ink in own periphery; a pair of inking roller receiving arm 30 for supporting both ends of an axis core 21 of the inking roller 20; a plate cylinder 40 pressed by the inking roller 20 and making the ink maintained in the inking roller 20 transfer to the own cell; and an impression cylinder 50 for sandwiching a transported printing object 11 together with the plate cylinder 40 and making the ink transferred to the cell of the plate cylinder 40 transferred to the printing object 11. Each inking roller receiving arm 30 has: a body 31 fixed to a stand; a support part 32 for pivotally supporting the end corresponding to the axis core 21 of the inking roller 20; and an adjusting mechanism 80 installed on the body 31 and supporting the support part 32, and can adjust a distance between the body 31 and the support part 32.
