1. Spray coating is a manual operation. The working speed is slow and the coating quality is poor. It is suitable for the coating of printed materials with small batch and rough appearance.
2. Printing and coating is usually used for glazing coating after printing equipment modification. This method is better than manual spray coating, and the production efficiency is also high. It can use existing printing equipment, one machine is dual-purpose, simple and easy to use, suitable for all kinds of printing plants glazing coating processing; 3 Special glazing coating machine coating, vacuum laminating machine can achieve accurate control of coating amount, coating quality is stable and reliable, suitable for glazing coating processing of various grades of printed products, currently the most commonly used coating method .

The temperature control of the rotary laminating machine process also affects and determines the hot-melt adhesive for laminating to solve the changes when heated, Huadu Printing Factory, and the resistance to the new heat. Therefore, strict temperature control is an important crux of pre-coating. According to our actual situation, it is more appropriate to control the temperature at about 80~100℃. Pressure: Appropriate pressure should be used while accurately grasping the laminating temperature, because the surface of the paper itself is not very smooth.
