Why do we need a humidifier in the printing workshop? Newspapers, books, and other printed materials are simply damp, and should be kept in a dry environment to prevent dampness. We usually don't use humidifiers in this environment. But in the printing workshop, if the air humidity is not good, it will lead to static electricity, paper wrinkling and the like. Therefore, the printing workshop has strict requirements on the humidity of the air. In the production process of the printing workshop, a humidifier is equipped to ensure that the air is Sufficient humidity:
Eliminate static electricity: paper is prone to static electricity. Workers often feel electric shock, accompanied by static thugs, especially in the dry seasons of autumn and winter. The strength of static electricity is closely related to the environmental humidity. Static electricity is most active at a relative humidity of 30%. The lower the humidity, the more active the static electricity.
2. Prevent elastic deformation: Because of the different types of paper, the swelling and shortening rates are different.
3. Prevent wrinkling: The reason why the paper wrinkles is because of the appearance of "ruffled edges" or "tight edges", which prevents the paper from being stretched flat and wrinkles during printing. This scene will cause the printer to show a lot of waste.
4. Dust reduction: The paper powder contained in the paper and the dust contained in the air fly around in the dry room, which has a varying degree of influence on the quality of the printed product.
5. Simple overprinting: the temperature and humidity of the printing environment, when the plastic intaglio printing is performed under the conditions of high humidity and low temperature, because the solvent evaporates fast and absorbs the heat around the ink film, the water vapor in the air is condensed sharply. Make the surface of the printing ink film form mist, causing the ink layer to lose its luster. The temperature and humidity of the printing workshop are important factors that affect the quality of the product.
