As the mold building mode is simple, adjustment is convenient in the operation process, and the probability of occurrence of defective goods can be decreased. Transparent adhesive tapes are stuck to one side and the periphery of each glass plate, and as the transparent adhesive tapes are made of a hydrophobic material, separation from resins is easy after resin curing and cleaning is convenient. The preparation method of the casting body plates is protected, the most important characteristic lies in that the mold is formed by assembling the two glass plates and the thickness controlling cushion blocks in a simple mode, and adjustment is convenient.

The invention brings forward a long-pressrun photosensitiser for printing of blanket and towel. The long-pressrun photosensitiser is prepared by mainly using a modified polyvinylalcohol aqueous solution, modified vinyl acetate, acrylate, an organosilicone monomer copolymer emulsion and modified photosensitive urethane acrylate. The photosensitiser provided by the invention has good long-pressrun performance. Without a long-pressrun paint, pressrun number can meet actual use requirements, platemaking process is minimized, and platemaking efficiency is raised. During production, use of the long-pressrun paint is reduced, and the damage of an organic solvent in the long-pressrun paint to workers and the environment is avoided.
