Product packaging and printing quality must be good to make consumers leave a good impression. No matter what kind of product packaging, such as medium and high-end tobacco, wine, cosmetics, health care products, food, medicine, etc., the packaging requirements are quite high. If you want the packaging to be so good, you must be accurate, and the printing effect should be good. Ink is also getting more and more attention, and the abrasion resistance of ink also affects the printing effect of packaging cartons. Under the premise of advocating environmental protection, traditional inks can no longer meet the current high-speed, environmentally-friendly printing requirements. Many merchants also recommend that packaging manufacturers use solid, environmentally friendly UV inks for printing. If the packaging has serious color differences, scratches, color fades, etc., the product will be returned or the cooperation will be interrupted. The physical performance of ink abrasion resistance is an item that must be tested daily by manufacturers such as medium and high-end packaging cartons. There are many factors that affect the abrasion resistance of ink, but it is super simple to consider from the three perspectives of the ink itself, the printing board and the temperature and humidity of the printing environment. What is the abrasion resistance of ink? It is mainly reflected in the cohesion and adhesion of the ink. When the cohesion and adhesion of the ink are reduced, the abrasion resistance of the ink becomes worse; it will also be affected by the temperature and humidity of the printing environment. When the weather and humidity increase, it is prone to packaging blur and deinking; it may also be affected by the water absorption of the printing paper. The water absorption of paper is low, so the water absorption of the ink is naturally reduced, and the ink floats on the surface and it is easy to cause deinking. Therefore, it is very important to choose inks with good quality. How to check the quality of inkjet printer inks?
