LV is a royal brand, a global famous brand. And the price is not cheap. Leading the fashion of the backpack. Now lv is popular with screen printing meshs for printing.
This shows that the prospect of screen printing meshs is great in the backpack manufacturing industry. It also shows that screen printing meshs are already the leader in the printing industry.
Choosing a good screen printing mesh requires looking at the manufacturer. Why? Manufacturer's production equipment, production technology. Quality supervision and so on are all important to see if a product is of high quality.
Screen requirements: Regardless of the material, you must confirm the requirements of the screen before selecting the screen. These requirements include: (1) ink resistance and other chemical materials to be used (2) mechanical resistance (3) edge resolution (4) Wire mesh bridging (5) Resolution The production of raw materials and production technology determines the quality of the screen product, and in the application process, the best printing quality depends on the operation method and the exposure and development equipment. 2. Chemical resistance: Chemical resistance is the basis for the ability to use different inks and cleaning chemicals. According to the screen system and its own chemistry, each system has a certain degree of chemical resistance, and the chemical resistance of different products has different degrees, which can be determined according to the chemical composition of the product. The screen system is based on the requirements of the ink. 3. Mechanicality: By selecting appropriate raw materials, the hardness and the elasticity of the material can be balanced to achieve the mechanical resistance of the screen. Factors affecting mechanical resistance are: screen tension and mechanical strength. Mechanical strength can include the number of prints. To achieve maximum tension, you need to operate it correctly. 4. Edge definition: High quality photographic paste particles are small and smooth. The reason for the poor quality of the screen graphics is that the edges are not flat and the edges are not clearly visible: overexposure or underexposure. Poor edge resolution affects the penetration and resolution of the ink on the screen, and the image is not fully visible. Edge definition can be observed with a 50X60x microscope. 5. The bridging property of the photosensitive material: the screen system
with good bridgeability of the photosensitive material makes the straight line straight; while the printed line of the photosensitive material with poor bridging performance is curved or jagged. Photographic bridging can be viewed with a 50x or 60x magnifying glass. The best effect is that the lines pass through the wire at a small angle. In the printing, any deviation from the original can be found from the bridging property of the photosensitive material. The screen is too thin, underexposed, overexposed, etc. are related to the bridging properties of the photosensitive material. 6. Resolution: Good resolution means that the screen can accurately display the thin lines of the original, so the requirements for the screen material are very high. The resolution of the screen is affected by the thickness of the screen (including the screen), the color of the screen, and the quality of the exposure lamp. , unexposed and overexposed, etc. Also, the resolution is affected by the particle size, edge definition, and mesh shape of the photosensitive material.
The above is whether it is a brand-name package, or other ceramic industry will use the screen printing mesh. There are screen requirements in the production of screen printing meshs. I believe the above content can bring us useful.
