Mainly pay attention to the following aspects when storing lithographic paper: The warehouse for storing paper should be higher than the ground by a certain height. The warehouse should be clean, dry and well ventilated. The windows should not be too large, they should be opened high, and must be small, and equipped with curtains to prevent direct sunlight on the paper. The temperature in the warehouse is 18 ℃ ～ 22 ℃, and the relative humidity is preferably 60% ～ 65%. The warehouse must be dedicated, and no other chemicals or items with high water content and fat content should be stacked in the warehouse. When the paper is placed on the ground, there should be a sleeper with a height of about 35cm. At the same time, the paper should be about 40cm away from the wall. Do not ventilate the warehouse after wind and snow or rain to prevent the paper from getting wet. In the rainy season, it is necessary to prevent mildew on the paper. When a small amount of mildew appears on the paper, use 3% formaldehyde aqueous solution to gently apply it. If there is more serious mildew phenomenon, sulfuryl fluoride can be used for fumigation treatment. Lithographic paper should be placed flat, not stacked vertically. After the flat paper is laid flat for three layers, it should be stacked into a cone when stacking upwards to prevent collapse. Smoking is strictly prohibited in the warehouse and should be equipped with necessary fire-fighting facilities. There should be no open wires passing through the wall, and no electrical appliances with open flames are allowed. A running account should be established, indicating the time of leaving the paper and the time of storage. The paper should be distributed according to the principle of advanced paper first out of the warehouse to prevent the paper from aging for a long time. Always check the condition of the paper, especially the good medicine in the spring and summer season to prevent the insects from biting. Do not unpack the paper when storing it. If the packaging is damaged, you should find a way to remedy it to prevent the paper from being directly exposed to the air, causing frequent exchange of moisture with the outside world around the paper, and causing undesirable deformation of the paper. The temperature and humidity of the printing environment and the temperature and humidity of the paper storage warehouse should not be too large, in order to prevent the paper from being transported to the printing environment and opening the package to produce large deformation of the paper. A certain channel should be reserved between different types of paper stacks to facilitate paper handling.
