There are generally two types of mounting methods: manual mounting and machine mounting.
Traditional hand-made mounting uses small powder to make paste. "A good craftsman uses paste like water. It only needs to be brushed more. If you brush too much, the water will penetrate the paper and it will condense like paper. It does not rely entirely on the power of paste." . "The frame is smooth and crisp, and the roll is comfortable and warm. Of course, it takes a lot of time and effort to frame a good work, which can take anywhere from a few days to several months. A high-quality mounting piece can be peeled off several times without hurting the painting. The large number of calligraphy and painting works handed down by ancient Chinese are the best evidence.
Machine mounting is a fast-food method introduced from abroad, using hot melt glue, chemical fiber fabrics and machine-made paper. Use a heat sealing machine and an iron to press and iron the painting center, backing paper and fabric with hot melt glue. Heat to bond together and serve immediately. It looks beautiful, and its mounting styles are much better than traditional hand-mounted ones. However, hot melt adhesive is insoluble in water, and once the calligraphy and painting mounted with it is damaged, it cannot be mounted again. The well-preserved machine-mounted calligraphy and paintings will also become brittle and cracked over time due to the aging and deterioration of the colloid and machine-made paper. This kind of framing also has a resounding name: "One-life goods". (This kind of mounting is mainly used in Japan for emergency mounting of beginners and children’s calligraphy and painting when exhibiting.)
