What Is Stamp Sand?

The photosensitive seal was invented by Japan in the early 1990's. It is made of a special chemical synthetic material that emits intense light radiation instantly through special equipment to cause photo-oxidation and thermal cross-linking on the surface of the material. seal.

Photosensitive seal

Compared with traditional seals, the biggest feature of photosensitive seals is that in addition to Chinese and English characters, complex patterns, portraits and even photos can be directly made into seals, and the chapter surface is clear and full. Therefore, the photosensitive seal, also known as the fashion seal, cartoon seal, portrait seal, photo seal, photo seal and so on.

The photosensitive seal has the advantages of convenient and fast production (that is, order and make, and take), the printing surface does not shrink, deformation, clear and non-spreading, the printing ink does not fade, and it is used continuously. It is mainly reflected in the following indicators:

1. No need for printing table or printing pad, can be repeatedly filled with oil, continuous stamping, the print is clear and not deformed; that is, the cover is dry and easy to carry.

2. In the case of proper use, as long as the ink is replenished, it has a service life of more than 10,000 times, and the print does not fade.

3. Can stamp on plastic, coated paper, glass, clothes and metal.

4. Unique design, different from atomic seal.

5. You can flexibly design unique seals according to your favorite pictures.

6. Equipped with oil injection (storage) device to facilitate repeated oil injection.

Chapter shell, photosensitive seal pad,

One or several times of refueling method Some seals may only be covered a few times at a time. If too much refueling is used, it is also a waste to place there, and after a long time, the ink volatilizes and thickens, which will cause damage to the seal pad. Therefore, adding a little oil before a small amount of use saves and protects the seal. Refueling method: Remove the stamp cover, and then remove the stamp body with the letter face down. There will be an oil filling hole on the back. Use a small amount of photosensitive ink to fill the oil filling hole. After the oil slowly penetrates, add an appropriate amount as required. Then put it back in place, so that it can be used (see Baidu experience "the correct method of photosensitive seal refueling" ^[1] ). 2. When the photosensitive seal is used in a large amount, the above refueling method is not available. Refueling should be performed from the filler port under the seal handle. Method: Put the seal on the table, pull the cap of the oil filling port under the handle, pull a small bottle of ink (if it is a large bottle, it is better to use a syringe or the like). Add it. If the oil seal is too small, the seal cannot be added smoothly. You can shake the seal slightly to let the oil flow in naturally. Photosensitive seals usually have a sponge body that stores oil. It will temporarily absorb excess oil and then slowly penetrate down into the photosensitive pad, so when using a small amount of seals, do not refuel like this! Third, there is another method of refueling, which is to remove the photosensitive pad, put it into the ink, literally enter it, the ink should not exceed the thickness of the photosensitive pad, and let the photosensitive pad slowly absorb the ink. If the stamp has a sponge body, you can put some oil in it. After the photosensitive pad is completely filled with ink, remove it and place it in the stamp case.
