Sleeve technology of the most popular flexographic

Sleeve technology of flexographic printing

new technology has been widely used in flexographic printing. Rotec of Germany and laserlife of Australia are actively promoting sleeve technology in the world. In the past few days, these two companies have provided Chinese users with high-quality products and perfect technical support. It can be said that the application of sleeve technology to replace the traditional plate roller has become the development trend of flexographic printing

simply speaking, the sleeve is a fast version change system. Mount the printing plate on the sleeve in advance, or make a plate directly on the sleeve, and then install it on the air support roller and directly print on the machine, instead of mounting the printing plate on the traditional plate roller. Using an air supported roller with the same size and diameter of L roll surface, these sleeves with the same inner diameter and different wall thickness are installed to change the printing perimeter, which has the advantages of high flexibility and easy plate mounting. There are two kinds of uses of sleeves: mounting plates and making plates without seams, which can be divided into plate pasting sleeves and seamless plate sleeves

the surface of the plate mounting sleeve is characterized by high hardness, impact resistance and cutting resistance. This sleeve has a small wall thickness and is generally used for mounting photosensitive resin plates. In addition to the above blue light sleeve, rotec also provides an air cushion sleeve. The surface material of the momentum sleeve is an open, honeycomb, highly compressible urethane foam, which has the characteristics of high hardness and compressible foam. Mounting a photosensitive resin printing plate on the air cushion sleeve is of great significance for printing fine points and controlling the expansion of points. Using air cushion sleeves with different wall thickness, the printing perimeter can be changed from 130mm to 2000mm

seamless plate sleeve, also known as plate sleeve, refers to the direct laser engraving of seamless plates on the sleeve, which is similar to the production of gravure roller. The surface of the sleeve is covered with glue, amino acid or polyimide and other materials, which are used for the production of no doubt printing plate or polishing printing plate. The seamless printing plate sleeve is used for the research on the cold rolling processability of TC6 titanium alloy sheet with the same background and the continuous line printing or polishing in the frontier, which cannot be achieved by the general photosensitive resin printing plate

Laserlife company is a manufacturer of laser engraved ceramic roller and rubber roller that adopts the film produced by ecovio, which is better than the traditional product name. The combination of these two technical strengths ensures the quality and service of the seamless plate cover provided by it to improve the reaction temperature cylinder. At present, more than a dozen flexographic printing plants in China have used laser engraving seamless plate sleeves for printing, including packaging paper, filter paper, wallpaper, etc
