What should I pay attention to when using seamless sleeve version?

Domestic flexo printing machines are gradually developing from narrow width to wide width, and the number of printing rollers and anilox rollers used is also increasing. Moreover, printing orders are changing from "small but big" to "big and small", which requires more frequent replacement of printing rollers and anilox rollers. Therefore, the importance of sleeve technology began to stand out. Foreign satellite flexo printing machines and unit flexo printing machines basically adopt sleeve technology. Although China started late, in recent years, the performance gap between domestic satellite flexo printing machines and foreign countries is getting smaller and smaller, and most new machines adopt sleeve technology. The printing unit of traditional satellite flexo printing machine adopts roller with shaft and anilox roller, which has the disadvantages of low efficiency, time-consuming, labor-consuming, poor safety, inconvenient storage, poor flexibility and nonstandard, and cannot meet the growing demand for short editions. Compared with the plate roller and anilox roller used in traditional equipment, the plate roller and anilox roller used in the printing unit of modern satellite flexo printing machine are very different: all of them are driven by servo motors, and the fast, light and safe sleeve plate changing technology is adopted, which constantly promotes the development of flexo printing in the direction of high quality, high safety and high standardization. The biggest difference between a seamless stencil and a flat stencil is that the seamless stencil has a ring structure, the innermost part is a glass fiber base, the middle layer is a photosensitive resin, and the outermost layer is a black film. The repeating perimeter of seamless overprinting specifications is 300 ~ 9 10 mm, the maximum printing width is 1750 mm, and the standard wall thicknesses are 1.573mm and 3. 165mm. It can also be made according to customers' requirements, and the wall thickness can be1. Select the appropriate outer diameter of the inflatable shaft. The outer diameter of the expandable shaft is determined by the repeated perimeter of the printed matter. The outer diameter of the inflatable shaft must meet the requirements of specific parameters. If necessary, a transition sleeve can be used to change the outer diameter of the expandable shaft. Transition sleeve is divided into hard sleeve and elastic sleeve. The elastic sleeve can not only change the outer diameter, but also reduce the printing pressure. Plate-making cycle: the plate-making time is 2 days when the materials are available, and the time for ordering raw materials with different specifications is about 25 working days.
