Both the oiling process and the laminating process are methods of protecting printed products.
The laminating process is to bond plastic films together with adhesives under heating and pressure to protect printed products; the oiling process is to apply a colorless and transparent oily coating on the surface of printed products to protect printed products.
The laminating process uses plastic film, and the processing uses chemical solutions such as benzene solvents, which does not conform to the concept of pollution-free, healthy and environmentally friendly printing. After the printed paper has been laminarized, it is difficult to recycle it, and it becomes a pollutant similar to white plastic. Therefore, from the perspective of environmental protection, the lamination process belongs to the non-environmentally friendly printing process technology.
The printing oiling process is also called glazing. Its function is to improve the glossiness of the printed surface and increase the reflective effect. Secondly, it is to improve the friction resistance of the printed product, so as to protect the printed product from scratches and moisture (it can be simply understood as applying transparent nail polish).
Oiling is the process of drying the ink directly on the printing machine during the printing process. It is the last step of printing to apply a layer of varnish on the surface of the printed product.
