1. Cold mounting: The method of mounting the protective film on the surface of the picture by cold pressing at room temperature is called cold mounting. Among them, there are single-sided mounting and double-sided mounting. In terms of operation methods, there are also artificial film mounting and self-revealing film mounting. The cold lamination process has the characteristics of simple operation, good effect and low cost. It is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.

2. Hot mounting: The mounting method of the special hot film on the equipment heated to a certain temperature (about 100-180°C) is called hot mounting, which can be divided into single-sided hot mounting and double-sided hot mounting. Good permeability and water resistance, good heat resistance, strong hardness, suitable for post-production of advertising pictures relying on lighting or other occasions. However, the heat lamination equipment and consumables are expensive, the operation is complicated, the energy consumption is large, and the cost is also high.
3. Vacuum lamination: Use a special vacuum lamination machine to vacuumize the space between the film and the painting and then shape it at a certain temperature to complete the lamination. The operation method is complicated, the cost is high, and the picture size is limited to a certain extent, but the mounting quality is high and the picture texture is strong, which is suitable for photos.
