In real life, many consumers have heard of sulfuric acid paper, but many people do not know what paper is sulfuric acid paper, how to use sulfuric acid paper. Because sulfuric acid paper is not common in daily life and work, but in some special printing and copying, sulfuric acid paper has an indispensable use.
    There is a very common type of paper in the papermaking technology and process of sulfuric acid paper. The scientific name is sulfuric acid paper, which is more common in the printing and advertising production industry. So, how to use sulfuric acid paper? The following is a brief explanation of the use of sulfuric acid paper.
1. A brief introduction to sulfuric acid paper
    Sulfuric acid paper is a kind of fiber in plants through fine fibers, which are interwoven with woven fabrics as raw materials, and then processed in a wet state by beating, papermaking, etc., without applying glue or filling in the process. Other materials are then soaked with a certain concentration of concentrated sulfuric acid. The soaking time is about two to three seconds, then it is washed with clean water and then treated with glycerin for a surface treatment, and finally dried to a film shape, and the texture is relatively hard.
    The sulfuric acid paper produced by the process has a compact texture and good hardness, the paper is slightly transparent, and is not breathable, and oil liquid and water cannot penetrate from it, and therefore has good waterproof oil penetration property, and Not mildew, easy to save. However, the printing sulfuric acid paper is more dry than other types of paper, so it is easy to generate static electricity due to friction between each other, so that it is easy to bring up a plurality of sheets of sulfuric acid paper or empty paper in the printing process.
Second, a brief description of the use of sulfuric acid paper
    In the above introduction to sulfuric acid paper, a small problem that occurs in the printing process of printing sulfuric acid paper is mentioned. In order to solve this problem, it is ensured that the paper can be smoothly fed during the printing process, and it can be printed before using the sulfuric acid paper. Drying it and maintaining the temperature and humidity of the printing job are relatively suitable. Because the paper is hard and stiff, the separation of the paper is more difficult than other papers of the same weight, which can increase the blowing and suction of the printing equipment. Big to improve the situation.
    In addition, since the sulfuric acid paper has a weak transparency after printing, it produces three kinds of optical principle expressions of absorption of light, reflection of light, and refraction of light, thus causing the actual color of the ink. The color observed after printing on sulfuric acid paper is not the same. In this issue, we must pay attention to the adjustment of humor color in the actual printing operation, and pay attention to the adjustment of ink dosage. When observing the color of the ink to be used, a layer of pure white paper can be placed under the sulfuric acid paper. In order to reduce the chromatic aberration that may occur in the naked eye, it should be noted that it is better not to use a denser and finer dot to print a sulphuric acid paper having a smoothness of less than 100 filaments, nor to add a too high number of screens.
    The above briefly introduces the details of the use of some sulfuric acid paper. Do you have a certain understanding of how to use sulfuric acid paper? For the usual production process, pay more attention to the details, there will be a great improvement for printing.
