Gravure printing is one of the four printing methods. Gravure printing is opposite to relief printing, in which the graphic part of the page is lower than the printing plane. The depth of concave on the surface of the plate is used to show the varying shades of the original. If the image and text part is deeply concave, and the amount of ink is filled, the ink layer left on the substrate surface is thick; if the image and text part is shallow, the amount of ink contained is small, and the ink layer left on the substrate surface after imprinting is thin. The amount of ink in the printing plate corresponds to the light level of the original text. In printing, the plate cylinder is first made to cover the whole plate through the ink trough or with an ink stick, and then the ink attached to the blank part is scraped off with an ink scraper, and the ink filled in the hollow hole is transferred to the surface of the substrate under appropriate printing pressure. Gravure printing has the advantages of high speed (up to 300 m / min), high printing resistance (up to 3-4 million prints), thick ink color, rich color, clear and bright, moderate contrast, vivid image and various product specifications. It can be printed on paper, aluminum foil, plastic flexible packaging, thick paper container, liquid paper, trademark and other substrates.
With the development of science and technology, the range of gravure printing at home and abroad is becoming larger and larger, which is suitable for printing of various materials, such as the preprint of color packaging boxes. The cartons produced by gravure preprint have better quality, higher strength and lower cost than those produced by traditional methods It also develops to multi-color (up to 12 colors), high-speed (more than 300m / min), automation (automatic registration control and strength control, etc.), and on-line (continuous processing of subsequent process and printing of gravure printing).
