Five types of screen printing techniques
Prints made by screen printing technology can be said to be everywhere around us, but we only understand that this is screen printing technology, as everyone knows, there are five technical classifications of screen printing. To say that these five types of screen printing technology classification, each of them has its own characteristics and advantages, and they jointly support screen printing, so that the printed matter around us is so diverse. Biyin Bazaar will give you a brief introduction to these five types of screen printing technology classification. 1. Flat screen screen printing: Flat screen screen printing machine is a method of printing on a flat substrate with a flat screen plate, when printing, the printing plate is fixed and the scraping plate is moved. 2. Flat screen screen printing: Flat screen screen printing is a method for printing flat screen printing plates on curved substrates (such as balls, cylinders, cylinders, etc.). When printing, the squeegee plate is fixed, the printing plate moves in the horizontal direction, and the substrate rotates with the printing plate. 3. Rotary screen screen printing: Rotary screen printing is a printing method in which the cylinder is equipped with a fixed ink scraper, and the cylinder printing plate and the substrate are synchronized to move at the same linear speed. 4. Indirect screen printing: the first three methods are directly printed 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 shape of complex, angular and concave surface and other special-shaped objects, it is necessary to use the method of indirect screen printing to print, the process is often composed of two parts: plane screen printing and transfer printing, that is, the screen printing image is not directly printed on the substrate, but first printed on the flat material, and then transferred to the substrate with a certain method. One of the methods of indirect printing, such as, first use the flat screen printing method to print the image on the flat glass, and then use the elastic silicone head, like a stamp, to absorb the ink image from the glass plate, and then pad printing to the special-shaped surface: another type of indirect screen printing method is flower paper transfer, such as: screen printing flower paper thermal transfer printing, screen printing flower paper pressure sensitive transfer, screen printing flower paper solvent activation transfer. Indirect screen printing has become a major area in the printing industry. 5. Electrostatic screen printing: electrostatic screen printing is a method that uses electrostatic gravity to transfer ink from the screen printing layout to the substrate surface, which is a non-contact printing method, which is to use conductive wire mesh as a printing plate, which is connected to the positive electrode of the high-voltage power supply; The negative electrode is a metal plate parallel to the printing plate; The substrate is somewhere in between. During printing, the toner on the printing plate has a positive charge when it passes through the mesh, and is attracted by the negative charge, scattered on the substrate, and then fixed by heating and other methods to form an imprint. At present, this method is mainly used for high-temperature substrates, such as the printing of furnace steel plates. Through these five types of screen printing technology, do you have a more thorough understanding of screen printing?
