The laminating process is a surface processing process after printing. It is also known as post-press over-molding, post-press silicone or post-press film. It refers to the film covering the surface of the printed product with a layer of 0.012~0.020mm. Thick transparent plastic film to form a paper-plastic product processing technology. Generally speaking, according to the process used, it can be divided into two types, namely, a coating film and a pre-coating film, and is classified into two types: a bright film and a matt film depending on the film material.
As a process for protecting and decorating the surface of printed matter, the film accounts for a large share of post-press processing, most of which are used in this way. This is because the printed film will be smoother, brighter, stain-resistant, water-resistant and wear-resistant. The color of the cover of the book will be more vivid and dazzling, and the wear resistance, folding resistance and tensile strength of the printed matter will be The moisture resistance has been greatly enhanced, which protects the appearance of various types of printed matter and improves the service life. Most notably, the film can largely compensate for the quality defects of the printed product, and many of the apparent defects that occur during the printing process can be covered after the film is coated (especially after the matte film).
