In the principle of imprint transfer, it is the principle of offset printing that uses the physical properties of water and ink to repel each other, and transfers the printing plate graphics to the tinplate via a blanket with the help of printing pressure. Due to the special physical and chemical properties of tinplate and the reprocessing performance of tinplate prints, tin plate printing process is quite different from ordinary offset printing. The printing process of tin plate is as follows:
Pre-press coating, tin plate printing, post-press coating, processing.
