The printed matter made by screen printing technology can be said to be everywhere we are, but we only understand that this is a screen printing technology. Everyone knows that there are five technology categories for screen printing. To say that these five kinds of screen printing technology classification, they have their own characteristics and advantages, by their common support for screen printing, so that the print products around us so diverse. Now let us briefly introduce the five screen printing technology categories. The
1. Flat-screen flat screen printing: Flat-screen flat screen printing is a method of printing on a flat substrate using a flat screen printing. When printing, the printing plate is fixed and the ink scraper is moved. The
2. Flat screen surface screen printing: Flat screen surface screen printing is a method of printing flat screen printing plates on curved substrates (such as balls, cylinders, cylinders, etc.). During printing, the squeegee is fixed, the printing plate moves in the horizontal direction, and the substrate rotates with the printing plate. The
3. Rotary screen printing: Rotary screen printing is a cylindrical screen printing plate. The cylinder is equipped with a fixed squeegee. The printing plate of the cylinder printing plate and the substrate are used for the simultaneous printing of linear velocity. The
4. Indirect screen printing: the first three methods all print directly on the substrate by the printing plate, but can only print some regular geometric shapes, such as plane, cylindrical surface, conical surface, etc., for the complex shape, angular and concave Surface and other shaped objects must be printed by indirect screen printing. The process is usually composed of two parts: flat screen printing and transfer, that is, screen printing images are not printed directly on the substrate, but are printed first. On the flat material, transfer to the substrate with a certain method. One of the methods of indirect printing is to print an image on a flat glass using a flat screen printing method, and then use an elastic silicone head to suck the ink image from the glass plate as a seal, and then print it to a special shape. On the surface: Another type of indirect screen printing method is the transfer of floral paper, such as: screen printing flower paper thermal transfer printing, screen printing flower paper pressure-sensitive transfer printing, screen printing flower paper solvent activation transfer printing. Indirect screen printing has become a major area of the printing industry. The
5. Electrostatic screen printing: Electrostatic screen printing is a method of transferring ink from a screen printing plate to a printing surface by means of electrostatic attraction. This is a non-contact printing method, which uses a conductive wire mesh as a printing plate. , and high-voltage power supply anode connected; negative is a plate parallel to the metal plate; substrate between two levels. During printing, the toner on the printing plate is positively charged when passing through the mesh, and is attracted by the negative charge and scattered onto the printing surface, and is then fixed to form a print by heating or the like. This method is currently mainly used on high-temperature substrates, such as printed steel sheets.
