What is a photosensitive seal? How to use it?

Photosensitive seal is a special chemical synthetic material invented by Japan in the early 1990s. It connects the photooxidation and heat on the surface of the material through special equipment, and emits strong optical radiation.

Photosensitive technology is a process of making seals by using the photosensitive characteristics of photosensitive materials. The special photosensitive material is superfine bubble material with small pore size and average pore size less than 30-956m, which has the characteristics of oil storage, oil source and flash melting. Photosensitive materials can absorb light energy and convert it into heat energy under strong light irradiation. The darker the color, the more energy it absorbs. During the exposure process, part of the light on the surface of the photosensitive material absorbed a lot of light energy, and the temperature quickly rose to the melting point. After flash evaporation, the melting temperature drops rapidly, forming a thin film with a certain thickness and strength, which plays a sealing role. Permeability of seal and insulation plays a role in pressure oil. This is the principle of photosensitive sealing photography.

Extended data:

Photosensitive seal has the advantages of convenient and quick production (that is, point-and-use and instant use), no shrinkage, no deformation, clear and non-diffusion, durable ink and continuous use. Mainly reflected in the following indicators:

1, there is no need for inkpad and inkpad, repeated oiling and continuous stamping, and the mark is clear and not deformed; Dry cover, easy to carry and so on.

2. Under the condition of proper use, as long as the ink is supplemented, it will have a service life of more than 654.38+00000 times, and the imprint will not fade.

3. It can be imprinted 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. Set the oil filling (storage) device to facilitate repeated oil filling.
