How to add stamping oil to Quanzhou’s new version of the special invoice seal?

First of all, you need to check whether your stamp is photosensitive or atomic. If it is atomic, it is added directly to the surface of the stamp. If it is photosensitive, you need to open the back cover of the stamp and inject it. But please note that atomic stamps can only be injected with atomic ink, and photosensitive stamps can only be injected with photosensitive ink. The two kinds of printing ink cannot be mixed. If used incorrectly, the seal hole may be blocked, the printing will not be clear, or the printing may not be printed at all.
