gravure printing cylinder making process

Also called conventional gravure engraving, diffusion-etch is the oldest method of gravure cylinder engraving. Hybrid Cylinders offer identical performance to the current traditional ‘gravure printing ‘ cylinder and (like for like) are lighter, and easier to handle, resulting in faster press changeovers Diameter variable Hybrid Cylinders reduce stored cylinder stock levels. 2)We have the professional design teams to serve customers,surface and reverse printing available. This is brought to you as another fulfillment of … 3)We have the strict quality system to make sure the quality of every process. It is an intaglio printing process where the image is engraved onto the surface of an image carrier below its nominal surface. The positive image and the screen are placed on top of a carbon tissue, a water-soluble paper covered with a light-sensitive gelatin resist, and consecutively exposed to ultraviolet light. This allows greater degrees of sharpness and detail. The shape and volume of engraved cells in the gravure printing process was analyzed. For more information about how our highly accurate gravure solutions can help with your application, please contact us. Ink is applied to the For more information on Gravure, we recommend contacting GAA, the Gravure Association of the Americas. non‐printing surface by ductor blade. In the diffusion-etch process, all cells are the same size, and the thickness of the membrane between cells—called the cell wall—remains constant. The method involves the surface treatment of the cylinder with mechanical means, the copper plating in an appropriate solution, the engraving of the cylinder, and the hardening of the cylinder by chromium plating. Gravure printing is an example of intaglio printing. It works well for CMYK printing where each color of ink is applied by its own cylinder and with drying steps in between. Gravure, unlike most other printing processes, prints from depressed, ink-filled cells produced on the surface of a copper-plated cylinder. We want to make Yungduk as a place every our people work happily and live together. Gravure printing routinely uses a wide variety of substrates: The depth and size of engraved cells determines the amount of ink that can be put on the substrate. Cylinders are extremely durable. 29 Nov 2009, 22:24 UTC. The copper is chrome plated for durability. – steel base cylinder width up – copper base layer about 2 mm thick polishing for high true running accuracy – copper engraving layer about 0.1 mm thick – chromium layer for high abrasion resistance about 0.006 mm thick. Like engraving, gravure is a form of intaglio printing that produces fine, detailed images. Gravure is small cells recessed into a cylinder that hold ink. Gravure is used for high volume work such as newspapers, magazines, and packaging. Gravure, unlike most other printing processes, prints from depressed, ink-filled cells produced on the surface of a copper-plated cylinder. This is because a gravure printing plant will house thousands of metal printing cylinders that can be repeatedly re-coated and imaged. Gravure printing can lay down more ink than other processes. The ink in the cells is then transferred to the desired substrate. A. Cylinder Making Process Machine 1. There are four basic means of engraving the image into a gravure cylinder: Diffusion-Etch Process. Production. Rotogravure, or gravure, is an old process. Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated and other … Gravure presses run at high production speeds: 3000-3300 feet per minute. It is an intaglio printing process where the image is engraved onto the surface of an image carrier below its nominal surface. Consequently, other materials such as special alloys or plastics can be used to coat the cylinder. 2)We have the professional design teams to serve customers,surface and reverse printing available.
