In the production of Tinplate metal container Arnold Mo printing, the drying of ink is a complex physical and chemical reaction process. It is necessary to reasonably control the drying speed of ink and master the physical and chemical mechanism of ink drying, so as to effectively carry out rapid printing operations and ensure product quality. If the ink dries too fast, it will reduce the normal transfer performance of the ink and affect the normal production; This will weaken the impression on the surface of the printing plate and ink roller, weaken the color of the ink, dry the ink, and hinder the transfer of the ink; The drying layer of the printing plate extends outwards; Excessive desiccant will lead to increased ink absorption, making the blank part dirty. However, if the ink dries too slowly, it will cause overprint difficulty, adhesion, adhesion, etc., The hardness decreases; It is easy to cause scratches during transmission. Therefore, the drying speed of the ink should be appropriate, not too fast or too slow. Because the substrate is tinplate, the auxiliary mechanism of the printing press is different from that of the paper offset press. Tin is insoluble in water and does not absorb solvent, so the ink of tin cans needs to be baked at high temperature to solidify the conjunctiva after solvent volatilization. Therefore, a drying chamber is usually required during the printing process. The full-automatic printing line for tinplate cans is generally 40-55 meters long, with sophisticated and huge equipment. In addition, the sheet printing press is controlled by Metal Cans And Closures Kenya Limited by separate and double magnets. The high hardness of the sheet material also determines that the advanced continuous iron feeding structure cannot be used in the printing process, which is different from the offset printing press in the structure of pushing, positioning and stacking parts.
