Screen printing screen printing is one of the types of orifice printing. Its basic principle: the screen printing part of the mesh part is relatively transparent to the ink. Missed on the substrate. Part of the inability to pass the ink is that the rest of the plate is blocked by the other parts of the plate. We cannot form a blank on the ink or on the substrate. In such a plate making method, the screen is a support body, the screen is stretched on the frame, and then the photoresist is applied on the net. Form a photosensitive template. Then, the bottom film of the picture is closely attached to the plate to be printed on the plat
e. After exposure and development, the portion of the plate that does not need to be inked is exposed to light to form a cured plate film, which blocks the mesh, does not penetrate the ink during printing, and needs to be printed on the plate. The mesh of the inked portion is not closed, and the ink is transmitted during printing to form ink on the substrate.At the time of printing, the ink is poured into one end of the screen printing screen, and the ink does not leak through the mesh on the substrate without any force. When the ink is scraped with a squeegee at a certain angle of inclination and pressure, the ink is transferred to the substrate under the screen by screen printing, thereby realizing image reproduction, which is screen printing. Screen printing originally used silk as a mesh material, so it was called screen printing in the world. Today, the mesh is replaced by a large number of synthetic screens, also known as screen printing. Because screen printing can use a wide variety of inks,
