Over the years, China has made significant progress in the printing industry, transforming from a country that once lagged behind in producing PCB inks to one of the top players globally. Today, China ranks second in total output value within this sector. This growth is not just about quantity but also quality, as Chinese silk screen printing inks now align with global standards and even lead in some areas.
Silk screen printing ink is a broad category, and there are various ways to classify it. It can be divided based on its composition, drying method, the material being printed on, and even the physical state of the ink. Common types include UV curing inks, fast-setting inks, air-drying inks, low-temperature thermosetting inks, and high-temperature inks. Each type is designed for specific applications and environments, offering versatility in the printing process.
One thing that many printers might overlook is the change in color tone between the wet and dry states of the ink. Some inks may appear lighter or darker after drying, depending on their formulation. For instance, when using solvent-based inks that dry naturally, the color usually remains consistent on materials like plastic, metal, paper, or glass. However, with ceramic inks, the color often changes during the firing process due to oxidation, making it necessary to rely on experience for accurate color matching.
For inks that use heat or light to cure, such as thermoset or UV inks, the color depth can shift slightly. When working with large volumes, using an ink adjuster can help achieve the desired shade quickly and efficiently.
It’s also important to store silk screen printing inks properly. Once opened, UV inks should be kept in a cool, dark place—ideally in the refrigerator—and protected from direct sunlight. Users should always check the shelf life of the ink and avoid mixing different brands or series, as this can affect performance and consistency. Proper handling and storage ensure optimal results and extend the product's lifespan.
