We understand that printing firms vary in size, and that’s why we produce a range of engraving machines. At Laser Engraving Manufacturers, we have all these machines for you. ("Gravure Process and Technology" 7) Gravure is a direct printing process: the image on the cylinder is printed directly to the substrate. An original is scanned into a computer, the various image densities are determined, and lasers etch the cylinder. This can be done by a chemical or a mechanical process, but is much more quickly done chemically. The technology enables the machine users to make even the most complicated printing plates automatically. Chrome polishing remains unchanged. Photoengraving - Photoengraving - Gravure and rotogravure: The gravure printing process is one of the three major processes that are used for catalogs, magazines, newspaper supplements, cartons, floor and wall coverings, textiles, and plastics. surface of the gravure cylinder. The method includes determining the coverage of the liquid composition desired, and then selecting parameters including the stylus angle and compression angle. Besides electromechanical engraving, all workflow processes for other modern gravure cylinder engraving procedures such as laser assisted etching and laser engraving are explained. Electronic Engraving Machine and Laser Engraving Machine Professional Manufacturers, © Copyright Laser Engraving Manufacturers. The plate materials could also be rubber or photopolymer. A traditional strategy towards the design of an engraving for the gravure cylinder has been reliance on a large inventory of finished cylinders having different engraved cell … Similarly, if you want to produce packaging for a certain brand, then gravure printing would be the best option for you. The image of the text to be printed is contained in the depression or the recesses on the surface of the printing plate. The latest gravure engraving method is Laser Cutting Process. With its reliable and high quality results, electro-mechanical engraving belongs to the well established engraving techniques in the market. Light areas and highlights result in deeper cells. Besides electromechanical engraving, all workflow processes for other modern gravure cylinder engraving procedures such as laser assisted etching and laser engraving are explained. Laser Engraving update We currently have three installations. The unexposed resist is washed away by the solvent. Consistent colour reproduction High-speed printing Widest presses Ink dries upon evaporation Engraver shield is closed once the engraving starts When image carriers for offset lithog-raphy and flexography were prepared with films in the 1980s, gravure cylinder engraving had already gone digital. Explain the process of Rotogravure (Gravure). Rotogravure printing is considered the highest quality printing process available, especially for films, and allows for high-output, high-speed printing. The process consists of a diamond stylus controlled by electronic means to cut cells into gravure cylinder surface. Replace cylinder 5. The characterization of gravure cylinders was carried with an accuracy greater than 0.5% in cell volume. Each is an electronic signal, which may range in intensity beginning from zero to 100 percent. From this the cell width, channel width and wall width are calculated. … Cell ink then gets transferred to the desired substrate. The first is in Belgium, a packaging printer. The basic principles of gravure printing are similar to engraved copper roller printing, so the initial step is to engrave the metal pattern cylinders. These are then exposed to the ultra-violet light. The depth and the size of the cells that engrave by the stylus determine the ink volume that will be transferred to the substrate.
