Tactile texture is extremely direct. Even the blind can sense it by touching it. However, once it is photographed, the directness of tactile cognitive texture is lost.
In recent years, in order to allow people to perceive the tactile pleasure on the surface of packaging materials such as paper, a wide variety of special paper materials with different textures are often used, such as embossed paper and mesh paper, which are dazzling. The surfaces of offset paper, coated paper and special paper have obvious differences in touch texture, and thus their artistic expressiveness is also different.
