Description

[0002] Printed matter is a general term for various finished products produced using printing technology. In recent years, with the continuous progress of detection technology and the increasing richness of materials, in order to enhance the visual effect or enhance certain properties of the surface (such as wear resistance, corrosion resistance, etc.), the surface of the printed matter often needs to be covered with multiple layers of materials.
