Paper coating is a process that involves applying a layer of material to the surface of paper to enhance its properties. This coating can improve the paper's appearance, making it smoother and glossier, which is particularly beneficial for printing. Common materials used for coating include clay, latex, and other substances that help achieve the desired finish. Coated paper is often used in various applications, such as magazines, brochures, and packaging. The coating not only enhances visual appeal but also provides better ink holdout, resulting in sharper images and text. This makes coated paper a popular choice in the printing industry.
