The surface of the anilox roller is composed of countless small concave holes with uniform size and uniform distribution, which are called ink holes. As the ink carrier, the ink hole has the functions of ink storage and ink distribution, and can effectively overcome the phenomenon of flying ink in the case of high-speed operation. The latest development of laser engraving anilox roller technology, the angle a of the ink holes is mainly 30 degrees, 45 degrees, 60 degrees, and 90 degrees, and the arrangement of the ink holes can be staggered or parallel to each other. Because the engraving process is computer-controlled, the anilox roller and its ink pockets can be reproduced repeatedly. Some people abroad suggest that the engraving angle of the ink hole of the anilox roller is 60 degrees.
