Description

Technical Field

[0002] A gravure printing press is a machine that uses a gravure plate for printing. The image and text part of the printing plate is concave, while the blank part is on the same plane as the outer circle of the plate cylinder. When printing, the entire plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a doctor blade, leaving the ink on the image and text part. The paper is then passed, and the impression cylinder is pressed on the back of the paper, so that the ink in the concave part is directly transferred to the paper. Finally, the printed matter is stacked or rewound in the paper delivery part. When using it, it is also necessary to consider the use of the winding device before feeding to ensure that it will not affect the subsequent printing quality.

[0003] However, it still has some shortcomings. For example, when rolling up the roll material, traditional printing machines are prone to inaccurate roll positioning, causing the rolled paper to shift.
