offset positive ps plate

positive ps plate(ISO 9001 Approved) 1.High Resolution 2.Long Run Length 3.Excellent Hydrophilicity 4.High Sensitivitypositive ps plateSpecifications:Aluminium Thickness: 0.15-0.40mmAluminium Width: Less than 1200mmApplication: books, periodicals and top grade color printAlloy aluminium alloy : 1050H18Resolution:8-10μmDot reproduction:2-98%Sensitivity: highCoating: greenRun length: 80,000-150,000Run length is always dependent on exposure,developing,processing and printing conditionsProperties(1)Moderate grainMultilayered 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 resolutionSpecial 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 lengthSpecially selectedcolophony in the coating of SHP-I significantly increases the press life of the plates.(4)Excellent hydrophilicityHydrophilic treatment is adopted on the basis of oxidization. By this process, quick ink-water balance are abtained.(5)Excellentchemical resistanceUnique coating recipe offers excellent durability and chemical resistance(6)Image visibility after exposureSharp color change after exposure, making it easier to check the image.(7)Air eduction layerElectrostatic 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
