The first three methods directly print the substrate from the printing plate, but only print some regular geometric shapes, such as plane, cylindrical surface, conical surface, etc. For shaped objects with complex shapes, angular and concave surfaces, Printing by indirect screen printing, the process often consists of two parts: flat screen printing and transfer, that is, the screen printed image is not directly printed on the substrate, but printed on the flat material first, and then used A certain method is transferred to the substrate. One of the methods of indirect printing is to first print an image on a flat glass by flat screen printing, and then use an elastic silicone head to draw an ink image from the glass as stamped, and then transfer it to the profile. Surface: Another type of indirect screen printing is transfer paper, such as: screen printing paper + thermal transfer, screen printing paper + pressure sensitive transfer, screen printing paper + solvent activation transfer Printed. Indirect screen printing has become a major area of the printing industry.
