CPP Film Printing Machine

CPP film printing machines are widely used in high-quality printing fields, such as packaging materials, decorations, and color newspapers. CPP film printing equipment uses gravure printing, in which the image part is concave and the blank part is convex, which is opposite to the layout structure of letterpress printing machines. CPP film printing equipment is usually equipped with advanced control systems, such as PLC and human-machine interface, to achieve automated production and improve efficiency and accuracy.

During the printing process, the entire plate cylinder is inked, and then the ink on the blank part of the plate is scraped off by the scraper, leaving the ink on the image part. Subsequently, the paper or other substrate is contacted with the plate through the impression cylinder, and the ink in the concave part is transferred to the paper surface, thus completing the printing.

When the rotogravure printing machine prints a single color, the plate is first immersed in the ink tank and rolled, and the entire surface of the plate is then covered with an ink layer. Then, the ink layer belonging to the blank part of the plate surface is scraped off, the convex part forms a blank, and the concave part is filled with ink. The deeper the concave part, the thicker the ink layer. The CPP film printing equipment transfers the ink in the recessed part to the printed material through pressure to obtain the printed product.
