The basic principle of photosensitive seal machine is to use the photosensitivity of special materials to form an airtight film on the surface of seal where there is no need to imprint, so as to achieve the effect of seal. Therefore, it is fast to use photosensitive seals as seals. The advantages of photosensitive seal are that the machine is cheap and not easy to break, the imprint is clear, the text accuracy is high, and it is convenient to use, and it only takes 10 second exposure. You don't need to get inkpad every time you stamp, so the printed body is generous, beautiful and durable.

Photosensitive bronzing machine (commonly known as photosensitive bronzing machine, portrait bronzing machine and wedding bronzing machine), as the latest seal in the world, is rapidly popularized in China and has become an upgraded product of China seal industry because of its simple and quick production, clear seal, long service life and strong applicability. With the promulgation and implementation of the standard GA 24 1.9-2000 of the Ministry of Public Security, the photosensitive seal machine has been recognized as the first choice for reaching the standard. This product has the advantages of convenient and fast production (customers can take it immediately), continuous hot stamping100000 times, no shrinkage and deformation of the printing surface, clear and non-diffusion of the imprint, lasting and non-fading printing oil, continuous oiling and continuous use. 0. 1 mm anti-counterfeiting stripes can be made. Independent exposure box design, precise alignment. Higher exposure efficiency, sufficient energy and lighter machine weight. The whole machine has beautiful appearance, simple operation, and all padding materials are exposed and formed at one time, which is durable.
