[0002] PVC decorative film is a new decorative material made of high molecular polymer PVC (polyvinyl chloride) as the main raw material, by adding various additives, calendering, compounding and other processes. PVC decorative film printing is a process of printing patterns, texts or textures on the surface of PVC decorative film. In the printing of PVC decorative film, multiple overprinting techniques are often used to achieve better printing effects through multiple and various printings. For PVC decorative film printing, commonly used ink types include PVC ink, which is an ink specially used for printing PVC materials. PVC ink has good printability, wear resistance, adhesion, washability and weather resistance, which can ensure the durability and clarity of the printed pattern.
