What is the significance of painting and calligraphy mounting? Be specific.

If you are asking about China's painting and calligraphy mounting:

First, the main purpose of painting and calligraphy mounting in China is to reinforce the painting and calligraphy works of art. Through the mounting process, the paper that absorbs water and deforms after painting will be leveled (except for deformation). Specifically, China's paintings and calligraphy are usually painted on paper or on the surface of textiles (silks and silks). These materials are light, thin, easy to deform, and have poor compressive and tensile strength, which is not conducive to the long-term preservation of works of art, especially paper paintings. Xuan paper with excellent water absorption is usually used, which will be obviously deformed after water absorption and drying, destroying the ornamental effect. Through the step of painting, the mounter can restore the crumpled paper to smoothness, restore the best viewing effect, increase the thickness of paper or silk and increase the strength of the material itself. In addition, through the installation process, the thickness and strength of the substrate are further increased. In addition, with the vertical shaft or hand scroll, calligraphy and painting works can be preserved when rolled up for storage, which not only saves space, but also avoids deformation and damage under external pressure.

Secondly, China's painting and calligraphy mounting also has a very important purpose, which is to beautify the works and provide better viewing effect. In the long historical process, painting and calligraphy mounting itself has developed into a mature cultural and artistic style, and different mounting forms have different names and meanings. Later researchers can also make a more accurate textual research on the life experience of the artwork itself through mounting. )
