Print plates are consist of metallic material, plating by chrome and copper outside, one by one steel pit corresponds with original design artwork and plate surface. Print plates are the basis of gravure printing and directly relate to the printing quality. Before curving the plates, design artworks need be confirmed repeatedly to avoid any mistake by the Union Packing and the client both. When the plates arrive at Union Packing, our specialized personnel will review to ensure the correctness.
What is the scope of examination? To inspect lattice point orderly and complete or not, less chrome or not after plating, check the text, the lines are complete and not missing. After detailed examination, the plates can be installed into the gravure printing machine. When install plates, pay more attention to protect the plates from the damage being hit. After complete the preparation work, make appropriate adjustments and check the pressure, adjust the ink and scraping blade. In the process of formal printing, Union Packing printing workers check sample regularly, whether the overprint is accurate or not, whether the ink color is bright or not, viscosity and desiccation of the ink. The environment of gravure printing need good ventilation equipment to eliminate harmful gases, recovery plant for solvent and explosion protection to avoid catching fire.
Gravure printing plates can be used for a very long time and are suitable for mass printing. The larger the batch, the higher the benefit.
