Is the work in the printer's plate-making room harmful to human health?

Generally, it won't, because all printers used for printing and plate making have shading protection devices, which can effectively prevent ultraviolet rays from directly radiating to the human body, so don't worry.

However, if you directly irradiate the human body, it will have a great impact on human health. The data show that ultraviolet rays have not found any other beneficial effects except promoting the synthesis of vitamin D, preventing rickets and sterilizing human skin, but their harm has aroused widespread concern.

1, ultraviolet rays can do harm to eyes. Cataract is considered to be the main cause of excessive ultraviolet radiation. After ultraviolet irradiation, most of the radiation is absorbed by the nuclear protein of corneal epithelium, which leads to cell expansion, fragmentation and cell death, and even damages the cornea and lens, leading to opacity. Generally speaking, ultraviolet radiation increases, and the number of human cataract patients increases.

2. Ultraviolet rays can cause harm to human skin. The influence of ultraviolet light is cumulative, and its main mechanism is that protein is irradiated by ultraviolet light to form photolysis products. In addition, its solubility, viscosity, thermal denaturation sensitivity, fluorescence and other physical, chemical and optical properties have changed significantly. The effects of ultraviolet rays on skin can be divided into acute effects and chronic effects. The acute effect is erythema effect, and its symptoms are edema and desquamation. Systemic symptoms include chills, fever, nausea and rare circulatory failure. Chronic effects such as skin aging, pigmentation, accelerated aging, and even tumors. Mild skin edema and erythema, severe blisters or bullae, accompanied by shock, fever, chills, nausea, palpitations and dizziness.

3. Damage of ultraviolet rays to other parts. The influence of ultraviolet rays on the immune system, some components of the immune system exist in the skin, and the skin is irradiated by ultraviolet rays, so that the immune system is irradiated by ultraviolet rays and its function is disturbed. Studies have shown that the immunosuppression of ultraviolet radiation will lead to skin cancer and some infectious diseases.
