What's the difference between atomic ink and photosensitive ink?

Photosensitive ink is mainly used for photosensitive seals, and the surface of the seal is black and flat. As the latest seal in the world, compared with the traditional seal, the biggest feature is that besides Chinese and English characters, complex patterns, portraits and even photos can be directly made into seals, and the account books are clear, the details are fine, the applicability is strong and the service life is long.

2. Different textures:

The difference between atomic seal and ordinary seal is that its ink can be used repeatedly after one injection, which can ensure clear handwriting, uniform and bright ink, strong anti-counterfeiting and is not easy to be made by ordinary tools. However, the atomic seal will be deformed after being used for a long time, which makes it impossible for banks to check the authenticity of bills.

Material composition photosensitive ink and atomic ink are different in material composition. The composition of photosensitive ink belongs to water-based ink, which is a mixture of pigment, dye, binder water and a small amount of alcohol. It is a solvent processed by photoprocessing technology photosensitive polymer, and its formula is commonly known as photoresist, also known as photoresist.
