Automatic Rotogravure Printing Line

Roto Gravure Printing LineThe rotogravure process is a direct transfer method for printing onto wood-pulp fiber based, synthetic, or laminated substrates, including:• Films such as polyester, OPP, nylon, and PE• Papers• Carton board• Aluminum foilThe modern day rotogravure printing press uses a printing cylinder which has been laser engraved with minute cells capable of retaining ink, the size and pattern of which reflect the required image. These cells are forced to transfer their ink directly onto the substrate by a combination of pressure and capillary action, so producing the printed image.The process, also commonly called gravure printing, is used in the manufacturing of food and non-food packaging, as well as labels, wall coverings, transfer printing, and has a variety of further applications in the security printing, industrial, and tobacco segments of industry.Advantages of Roto Gravure Printing Line:-The rotogravure printing process is the most popular printing process used in flexible-packaging manufacturing, because of its ability to print on thin film such as polyester, OPP, nylon, and PE, which come in a wide range of thicknesses, commonly 10 to 30 micrometers.Other appreciated features include:• printing cylinders that can last through large-volume runs without the image degrading• good quality image reproduction• low per-unit costs running high volume production• hi-speed performance• low ink consumptionDisadvantages of Roto Gravure Printing LineShortcomings of the gravure printing process include:• high start-up costs: hundreds of thousands of copies needed to make it profitable• rasterized lines and texts• long lead time for cylinder preparation, which is offsite as the techniques used are so specialized Roto Gravure Printing Line
