Several Ways to Improve the Printing Resistance of Printing Plate

   Several Ways to Improve the Printing Resistance of Printing Plate 

    1. Baking plate. After exposure, development and dirt removal, the PS plate is baked at 230-250 ℃ for a certain time to change the molecular structure of the original photosensitive layer and form a three-dimensional network structure, which becomes a solid graphic foundation.Several Ways to Improve the Printing Resistance of Printing Plate

     2. The positive PS version shall be kept away from light.Several Ways to Improve the Printing Resistance of Printing Plate

     3. The pH value of fountain solution shall be appropriate.Several Ways to Improve the Printing Resistance of Printing Plate

     4. Select the substrate with smooth surface and no impurities.Several Ways to Improve the Printing Resistance of Printing Plate

     5. Carefully adjust the contact pressure between the water roller, inking roller and the printing plate surface. The adjustment shall be carried out in the non graphic part of the printing plate.Several Ways to Improve the Printing Resistance of Printing Plate

     6. When the water roller and ink roller are in contact with the printing plate, the axial movement shall be as small as possible. When they are not in contact with the printing plate, their circumferential rotation shall be flexible and free.Several Ways to Improve the Printing Resistance of Printing Plate

     7. Select the water roller and ink roller with appropriate hardness and high roundness.Several Ways to Improve the Printing Resistance of Printing Plate

     8. Reasonably adjust the pressure between the rubber cylinder and the printing plate cylinder according to the machine operation manual to reduce the friction to the printing plate.Several Ways to Improve the Printing Resistance of Printing Plate

     9. Reasonably use the drying agent to prevent the ink from drying too early during transmission, maintain its rheology, and meet the needs of the remaining ink layer of the graphic part of the printing plate, so as to protect the printing plate.Several Ways to Improve the Printing Resistance of Printing Plate

      10. Be careful in process operation to prevent abnormal damage to the printing plate, especially to avoid horseshoe marks during taking and placing.Several Ways to Improve the Printing Resistance of Printing Plate 

     11. Before starting the machine, carefully check whether the printing plate has scratches, dirt and oil stains, whether the gluing is uniform, and whether there are foreign matters on the back of the printing plate and the liner.Several Ways to Improve the Printing Resistance of Printing Plate

     12. After long-time shutdown or dirt removal, apply a layer of uniform and appropriate thickness hydrophilic protective glue (such as gum arabic).Several Ways to Improve the Printing Resistance of Printing Plate

     Due to the low printing speed, slow ink curing speed, difficult control of printing quality and high consumption of printing materials, the flat screen printing method can not meet the needs of cigarette carton scale and mass production. Several Ways to Improve the Printing Resistance of Printing Plate

     The high-speed rotary screen printing production line is adopted, which has the advantages of high printing speed, high productivity, stable printing quality and low consumption. It changes the traditional flat screen printing, manual paper supply and ink supply mode, and is suitable for high-speed automatic and large-scale mass production of exquisite folding cartons.Several Ways to Improve the Printing Resistance of Printing Plate

     Web rotary screen printing uses nickel metal round screen printing plate, built-in ink scraper and automatic ink supply system. The ink scraper transfers the printing ink from the round screen plate to the surface of the substrate supported by the embossing cylinder. Several Ways to Improve the Printing Resistance of Printing Plate

    The whole printing process from paper feeding, ink supply, printing color registration, UV drying, etc. are fully automatically controlled by computer.Several Ways to Improve the Printing Resistance of Printing Plate

     The circular screen printing plate is suitable for large-scale rotary printing, with a maximum speed of 125m / min. the screen can be reused. Several Ways to Improve the Printing Resistance of Printing Plate

    Therefore, web rotary screen printing can not only meet the requirements of printing frosting, ice flower and other special effects, but also online hot stamping holographic anti-counterfeiting marks, concave convex tooth marks and die-cutting indentation, which is easy to realize high-speed automatic printing of cartons.Several Ways to Improve the Printing Resistance of Printing Plate
