Christmas Wrapping Paper And Boxes flexographic printing material and hardness is the guarantee of quality

The key factor affecting the quality of the printing plate is the hardness of the printing plate, the higher the hardness of the printing plate, the smaller the elasticity of the printing plate, the shorter the service life of the printing plate, the higher the clarity of the graphic dot, the smaller the compression deformation of the dot, but the corrugated supported by too much pressure has been damaged in different degrees, so the compressive strength of the carton is weakened, the lower the hardness of the printing plate, the greater the elasticity of the printing plate, the better the printing plate resistance. Long life and can be full contact with the rough substrate surface, so that the printing is fully inked, but the dot deformation is large and affects the quality of the printing, so the choice of printing plate plate and hardness is the guarantee of quality.

Solid photosensitive resin plate should be selected in flexographic printing, which has good ink transfer performance and wide tolerance. High reproduction accuracy, good stability, wear-resisting without deformation, long service life and convenient processing and other advantages, has been widely used, the hardness of plate material should be selected according to the different printing process and the hardness requirements of different graphics, field and line plate hardness in HS32-35, small print and dot plate hardness in HS37-42 is appropriate.
