The laminating of the automatic laminating machine is a process in the later stage of printing. The first thing is to cover the surface of the printed product with a layer of plastic film to achieve the effect of the printed product becoming smoother and brighter. The automatic laminating machine is divided into several categories according to the temperature and use of the original data used by the various materials and equipment. The laminating skills completed by the equipment are analyzed in the following categories.
        1. Cold mounting: The method of mounting the protective film on the surface of the image by cold pressing at normal temperature is called cold mounting, and there are single-sided mounting and double-sided mounting in between. There are also manual peeling and self-releasing films in the operating method Framed. The cold mounting technique 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 laminating of laminating machine: The method of laminating the dedicated hot film on the equipment heated to a certain temperature (about 100-180°C) is called hot laminating, which can be divided into single-sided hot lamination and double-sided hot lamination. Because of its good light permeability and water resistance, and strong hardness, it is suitable for the post-production of advertising images in other occasions. However, hot laminating equipment and consumables are more expensive, with messy operations, high energy consumption, and high costs. The automatic laminating machine vacuum laminating is to use a special vacuum laminating machine to evacuate the film and the painting and set it at a certain temperature to complete the laminating. Its operation method is messy, the cost is large and the picture scale is subject to certain. Limited, but the mounting quality is very high, the picture texture is strong, suitable for photos.
