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

摘要

PROBLEM TO BE SOLVED: To provide a web-fed rotary gravure press capable of compensating for color density difference (difference in right and left direction) that is possibly generated in the width direction of a printing object.SOLUTION: Each form roll receiving arm includes: a body part secured to a rack; supporting parts journaling corresponding ends of the shaft core of a form roll; and an adjusting mechanism attached to the body part and supporting the supporting parts, and also capable of adjusting a distance between the body part and the supporting parts. A control part controls the adjusting mechanism of each form roll receiving arm based on color tone of the printing object measured by a color tone measuring part, and adjusts the distance between the body part and the supporting parts of the form roll receiving arm.
