How to tell whether the official seal is atomic chapter or photosensitive?

The core of the difference lies in the different oiling, materials and service life of the two seals.

Atomic seal is to store ink in the inner core of the seal, and then make the inner core into the shape of the printing surface. Every time ink leaks from the inner core, there is no need to stamp the stamp pad every time, which improves the efficiency of office production. Photosensitive seal is a special chemical synthetic material, which emits intense optical radiation instantly through special equipment.

In this way, the surface of the material is sealed by photooxidation and thermal crosslinking, and? Atomic chapter is stipulated by the People's Bank of China that it cannot be used as a reserved seal. Every company must keep the reserved seal in the bank, and the reserved seal must be stamped on the bill when transferring money. Because atomic chapter is soft, the handwriting is easily deformed or blurred, and it has no anti-counterfeiting function.

Introduce the difference between them.

There is an obvious difference between oiling a seal and repeatedly oiling an atomic seal, so the ink is easy to volatilize and spread. Invert the seal, invert 3-4 drops of special oil for photosensitive seal (depending on the seal size and printing oil program) 10 minutes or more, and then gently wipe off the excess printing oil on the surface with a paper towel.

The service life is different. The photosensitive seal can be used for 654.38+00000 times at a time, and can be used continuously for about 100000 times. The life of an atomic seal depends directly on its material, and good raw materials can prolong the service life of the seal. The atomic seal products made of imported raw materials have stable quality, simple operation and few maintenance times, and can be stamped more than 10000 times, which can directly reduce the procurement cost.
