lithographic printing plate Specifications: Aluminium Thickness: 0.15-0.30mm Aluminium Width: Less than 1400mm Application: books, periodicals and top grade color print Alloy aluminium alloy : 1050H18 Resolution:8-10μm Dot reproduction:2-98% Sensitivity: high Coating: green Run length: 50,000-120,000 Run length is always dependent on exposure,developing,processing and printing conditions Properties of lithographic printing plate (1)Moderate grain Multilayered complex grain structure is formed on the surface of substrate through electrolysis graining and a series of chemical and electric-chemical methods. The formed grains are fine and full and could reach the multilayered structure to a great degree, which ensures more excellent dot reproduction and quicker ink-water balance. (2)High resolution Special ingredients, together with the optimally distributed formular weight of the binding of polymers in the coating of SHP-I offer fine dots with sharp edges and reproduce images with rich tone. (3)Long run length Specially selectedcolophony in the coating of SHP-I significantly increases the press life of the plates. (4)Excellent hydrophilicity Hydrophilic treatment is adopted on the basis of oxidization. By this process, quick ink-water balance are abtained. (5)Excellentchemical resistance Unique coating recipe offers excellent durability and chemical resistance (6)Image visibility after exposure Sharp color change after exposure, making it easier to check the image. (7)Air eduction layer Electrostatic spray technique is adopted during the production, which helpskeep better contact between films and plates. Therefore, shorter vacuuming time and better exposure of flat meshwork are achieved
