  Long run double layer thermal CTP plate is a specialized material for the printing industry with high abrasion and print resistance for long time and high speed printing. The double layer structure design improves plate stability and printing results while reducing the possibility of distortion and damage. Double layer thermal CTP plates have an important position in the printing industry, which can maintain high quality printing effect during the printing process, improve production efficiency and save production cost. The structure of long run double layer thermal CTP plate typically includes multiple key layers to achieve its unique imaging and printing properties. Specifically, the structure may include: - Aluminum backing layer: serves as the bottom support of the plate and provides a stable substrate. - Photographic Layer: This layer typically contains infrared absorbing dyes or other thermally sensitive materials that are used to absorb the energy...

  CTP (Computer-to-Plate) plate is a kind of high-precision photographic film used in the printing industry, which is mainly used to make printing plates. The CTP plates cost will be affected by a variety of factors, including the specifications of the plate, the brand, the material, the quality, the supply and demand situation in the market, and the purchasing quantity, etc. The price of CTP plate will vary according to the specific type (e.g. thermal CTP plate, violet CTP plate, etc.). Generally speaking, the price of high-quality, high-performance CTP plates is relatively high. The following is the price range of CTP plates in general: 1. Price per square meter: - The CTP plates price generally ranges from US$4-8 per square meter, depending on factors such as brand and specifications. High-end brands and special specifications of CTP plates may cost more. 2. Price per plate: - Generally speaking, the specification of CTP plate is 0.3 m x 0.4 m (12 inche...

  CTP plate, or Computer-to-Plate, is a special plate used in the printing industry. It allows the figures, pictures or pages edited in the electronic pre-press processing system or color desktop system to be transferred directly to the printing machine for printing without the need of subsequent plate making process. CTP plate is a high-end product of PS plate, widely used in offset printing plates such as sun-picture PS plate, heat-sensitive CTP plate, light-sensitive CTP plate, UV-CTP plate, and so on. Types of CTP plate : There are four main types of CTP plates classified according to the imaging principle of plate making: photographic system CTP plates, thermal system CTP plates, violet laser system CTP plates and other system CTP plates. Among them, the photosensitive system CTP plate includes silver salt diffusion plate, high sensitivity resin plate and silver salt/PS plate composite plate; the thermal system CTP plate includes thermal cross-linking ...

  The production process of the photo sensitive aluminum CTP plate base is mainly studied for the grit treatment and anodizing treatment involved. When the grit treatment, the surface roughening method, the concentration of hydrochloric acid, the temperature of the electrolyte and other factors are investigated. The influence on the effect of sand meshing treatment is obtained, and the appropriate process conditions are obtained. The concentration of hydrochloric acid is 8-10 g/L, and the temperature of the electrolyte is 30-60℃. During anodizing, the concentration of sulfuric acid, the temperature of the Oxidation time and the influence of impurities in the oxidizing solution on the effect of anodic oxidation, to obtain suitable process conditions, the sulfuric acid concentration range is 15%-30%, the oxidation solution temperature range is 25-30℃, and the oxidation time range is 40-60s. The concentration of aluminum ion in the liquid ranges from 0.5% to 5%. ...

  Good quality ctp printing plate has been in use for a long time, it has also begun to spread in world. CTP plate together with PS plate are still the most widely used printing plate. In offset printing, plate making is the guarantee of printing quality. Only by guaranteeing the quality of the PS and CTP plate can the quality of the printed matter be guaranteed. The original version refers to the film or sulfuric acid paper printed before printing, and its quality directly affects the production effect of the ctp plate . There are two important indicators of the original quality: in the sun chart, the points must have sufficient density, the single point density is above 3, the field density is above 3.5, and the transmission density of the blank area should be less than 0.05. The center density of the dots is the same as the edge density, which can increase the tolerance of the exposure time. The original version is clean and there are no tr...
