Graving printing:
Printing principles and features Gravure printing is a direct printing method. Its core principle is to use the depression of the image part on the gravure plate to store ink, and transfer the ink to the substrate through the pressure of the printing press to form clear patterns and texts. Printing principle: The printing plate of gravure printing is the key. Its image part is lower than the non-image part, forming a concave print. Ink is filled into these concave prints, while the non-image part remains clean. During the printing process, the pressure of the printing press transfers the ink in the depression to the substrate to form the required image. Features: Thick ink layer: The thickness of the ink layer of gravure printing is usually thicker than other printing methods, which can reach more than 20μm, making the printed color more vivid and three-dimensional. Bright colors: Due to the thick ink layer, gravure printing can achieve a high saturation color effect, which is suitable for printing high-quality color images. High print durability: The printing plate of gravure printing is durable and can withstand millions of printings, which is suitable for mass production. Wide range of applications: Gravure printing is suitable for a variety of substrates, including paper, plastic film, metal foil, etc., which can meet the printing needs of different products. Continuous printing: Gravure printing machines can perform high-speed continuous printing, which is suitable for the production of long-running printed products. Good anti-counterfeiting performance: Gravure printing is often used for the printing of securities, anti-counterfeiting labels and other products because its printed patterns are difficult to copy.Application scope Gravure printing is widely used in many fields due to its unique advantages: Packaging printing: Gravure printing is widely used in the packaging industry, especially in the printing of plastic flexible packaging, paper boxes, labels and other products, which can provide high-quality printing effects. Publishing and printing: In Europe and the United States, gravure printing is often used in the production of large-scale printed materials such as newspapers and mail advertisements. Securities printing: Gravure printing is suitable for the printing of securities such as currency, stamps, and securities due to its good anti-counterfeiting performance. Decorative printing: On decorative materials, such as wallpaper and decorative materials, gravure printing can print continuous patterns to increase the beauty of the product. Industrial printing: In the industrial field, gravure printing is used for printed circuit boards, decorative films for electronic products, etc., and is favored for its fine lines and thick ink layer. The high printability and bright colors of gravure printing give it a significant cost advantage in long-run printing. Although its plate making cost is high, the unit printing cost is low for large-scale printing, so it occupies an important position in the market.
