　　1. Become a master. The text and graphics of the silk screen nameplate are mostly produced through photo typesetting and photo plate making. First, make a single original and then combine it with a continuous dryer. According to the required accuracy of the parts, the layout with no spacing and the layout with spacing can be used separately. If the size of the sign is not high, it can be imposed without adding spacing. After printing, it can be cut directly or stamped after cutting. If the size accuracy of the sign is high, a layout with spacing should be used. After printing, punch holes according to the position of the positioning holes. The distance between each part can be 2mm, the positioning aperture can be 2mm, the hole spacing can be 4mm, and the total area can be 400400mm, or designed according to the process. If the colors of the screen printed logo are two or more, the photosensitive plate should have positioning rules. Positioning holes can be drawn on the photosensitive plate of the main pattern of the logo to ensure the positioning accuracy of the metal screen printed nameplate during cutting.

　　2. Positioning of Qingdao Dadong Silk Screen Nameplate Manufacturer. Positioning is the key to accuracy, and the accuracy of positioning is the key to determining the quality of metal screen printed nameplate markings. The rules on screen printing are a technical means to ensure accurate and uniform positioning of graphics on the surface of the same printing workpiece, and to meet the accuracy requirements of color overprinting.

　　3. Preparation of ink for metal screen printing nameplates. The requirements of silk screen nameplate ink for metal silk screen nameplate markings are strong adhesion, good wear resistance, clear printed graphics, fast drying, and no screen sealing. If there are color marks on the screen printing, you can refer to the relevant color printing ink color samples to adjust the ink. When adjusting the ink, add an appropriate amount of ink adjusting oil and desiccant. The amount of ink desiccant added is about 5-8% of the total amount of ink. It is difficult to dry with a small amount, but a large amount will affect the adhesion of the ink.

　　4. Quality requirements for metal screen printed nameplate markings. The text, scale, graphics, positioning holes, and color of the screen printed logo should meet the requirements of the drawing. The surface of the finished product should be free of obvious scratches and stains, and the ink film adhesion should meet the requirements.
