Application of Humidifier in Printing Industry

　　People in the printing industry know that humidifiers play a vital role in printing, especially in the autumn and winter of each year, when the air is particularly dry, when the paper is printed and bound with static electricity, it is a very difficult problem. When the humidity in the air is lower, the paper is more likely to generate static electricity, dust and other problems. These problems seriously affect the normal printing production and product quality. Because printing is a special industry, neither the humidification environment is larger than the ground nor the humidity in the air is too much. At this time, a humidifier is needed. What role does the humidifier play in the printing industry?

　　1、 Prevention of paper deformation: the shrinkage of different types of paper is not completely different due to different types of paper. If the humidity of the paper in the environment is relatively high, the paper will absorb water and expand. If the humidity of the paper in the environment is relatively small, the paper will shrink due to lack of water. When the paper is seriously deformed after receiving and shrinking, the printing machine cannot be used, otherwise the paper will break and the overprint will be inaccurate.

　　2、 Eliminating static electricity: when the captain shakes the paper when it is being cut, the feeling of being struck by electric shock will appear. This often happens in autumn and winter. The appearance of static electricity is mainly caused by the reduction of humidity in the air.

　　3、 Reduce dust: When the indoor humidity is lower than 50%, all the paper scraps and paper powder in the paper will fly everywhere in the air. By using a humidifier, the dust in the paper can be controlled to make it fall after absorbing moisture.

　　4、 Avoid wrinkling: when the moisture in the air is reduced, the paper will have tight edges, ruffles and other phenomena.
