How to choose inkjet printer ink?
Since its wide application, inkjet printers have been unanimously recognized by various industries. However, inkjet printers still have certain limitations in practical applications. Some industries require high temperature resistance and some The industry requires migration resistance, and some require corrosion resistance. Different types of manufacturers have very different requirements for inkjet printer inks. For example, flexible packaging products based on rubber and plastic materials have become one of the main packaging materials and are widely used in the packaging of food, beverages, tobacco and cosmetics. And these plastic materials are mostly PVC, PET and PE, which are the main printing objects of inkjet printers in the packaging field. Packaging materials require not only clear coding effects, but also beautiful appearance, so that the requirements for inkjet printer ink will increase. Generally speaking, the requirements for inkjet printer inks are mainly analyzed from the following aspects:
First, anti-counterfeiting. The anti-counterfeiting function of products has been paid more and more attention by merchants. As the carrier of product identification, ink also assumes this important task. An ultraviolet visible anti-counterfeiting ink on the market has good anti-counterfeiting properties. This kind of ink will not display under normal light, and can only be seen under ultraviolet light.
Second, quick-drying. The production speed of the production line continues to increase, which requires the cooperation of fast-drying inks. For example, in the processing and production of cigarette packs, the ink dries immediately after being sprayed on the surface of the product, and at the same time it is firmly attached to the surface of the product, and will not be printed to other locations and stain the surface of the object. The identification of printed products is clear, complete and easy to distinguish, does not affect the entire production process, and effectively reduces downtime.
Three, environmental protection. The ink and solvent of the printer are highly volatile substances, which will produce more chemical toxic residues and pollute the environment. Especially for food packaging, the environmental protection of ink is more important. Its chemical composition and odor may penetrate into the food through the film and packaging, harming human health. At present, printer equipment suppliers are paying great attention to the development of environmentally friendly inks.
