Silk-screen printing method used for panel

Abstract

The invention discloses a silk-screen printing method used for a panel. The method comprises the following steps that S1, a printing panel is placed on a carrying table; S2, a metal screen printing plate with corresponding patterns to be printed is placed on the bearing panel, and printing patterns of the metal screening plate right face the to-be-printed position of the printing panel, a clamp isused for clamping and fixing the metal screen printing plate and the printing panel, and the metal screen printing plate is made of hard metal or alloy of the metal; S3, printing ink is poured to thesurface of the metal screen printing plate, a scraping plate is adopted for scraping the ink to the printing patterns of the metal screen printing plate, the scraping plate carries out scraping to enable the ink to form corresponding patterns on the printing panel, and pressure of the scraping plate to the corresponding positions of the printing patterns of the metal screen printing plate is constant; and S4, the printing panel is dried to enable the ink on the surface of the panel to be cured. The metal screen printing plate made of the hard metal or alloy of the metal is adopted, the mechanical strength is high, the metal screen printing plate is not prone to wear and deform, the weather resistance is high, the metal screen printing plate is applied to silk-screen printing, the printingposition of the printing panel do not deviate, and the printing precision is high.

Description

technical field [0001] The invention relates to the field of screen printing, in particular to a screen printing method for flat plates. Background technique [0002] Screen printing refers to using a screen as a plate base and making a screen printing plate with graphics through a photosensitive plate-making method. Screen printing consists of five major elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the graphic part of the screen printing plate can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the movement. Part of the mesh is extruded onto the substrate. For example, the ap...

Problems solved by technology

However, this kind of flexible printing screen is still used. Because the screen is not close to the surface of the substrate during printing, but the screen is deformed under the pressure of the scraper so that the ink on the screen is in contact with the substrate. The printing structure is easy to cause damage to the screen printing plate. The printing screen plate has a short service life and affects the printing effect. When the screen is deformed, the printing is completed. When the mesh is deformed during the printing process, the accuracy of the printing position will be affected.
