The lamination process is a surface processing process after printing, and is also known as post-press lamination, post-printing lamination, or post-printing film. It refers to the laminating machine covering the surface of the printed material with a layer of 0.012 to 0.020 mm. Thick transparent plastic film forms a paper-plastic product processing technology. In general, according to the process used can be divided into coating film, pre-film two, according to the film material is divided into two kinds of light film, matt film.
As a method of protecting and decorating the printed surface, the surface of the printed matter that is covered by the film will be smoother, brighter, stain-resistant, water-resistant, and wear-resistant. The color of the cover of the books and books will be more vivid, not easily damaged, and the abrasion resistance of the print The folding endurance, tensile strength and moisture resistance have been greatly enhanced, protecting the appearance of various types of printed products and increasing the service life. What is most worth mentioning is that the film can largely compensate for the quality defects of the printed products. Many apparent defects appearing in the printing process can be covered after the film is covered (especially after covering the film).
