First, the film
The film is made of transparent plastic film which is more smooth and smooth to the surface of the printed matter by hot pressing. The color of the graphic is more vivid, and it also functions as waterproof and antifouling. It can be divided into surface processing and forming. Waxing and other processing techniques; molding process. The film not only makes the printed surface wear-resistant, folding-resistant, and chemical-resistant. However, since the plastic film is not degradable, it is difficult to recycle and easily cause pollution. Therefore, the plastic coating process should be used with caution when the glazing can be replaced.
Second, hot stamping
Hot stamping, also known as hot stamping, is a type of pattern or text that needs to be stamped, and a variety of aluminum foils are printed onto the substrate with a certain pressure and temperature, showing strong metallic light. To make the product have a high-grade texture. At the same time, aluminum foil has the function of protecting printed matter because of its excellent physical and chemical properties. Therefore, the hot stamping process is widely used in modern custom package printing.
Third, glazing wax
Glazing is to apply a layer of colorless and transparent paint on the surface of the printed matter, the gloss of the brush, and to protect the surface of the package from water and grease. The product is bright and has a good barrier effect. To form a glossy film to increase the imprinted wax is to apply hot melt wax on the wrapper.
Fourth, bump embossing
Concave-embossing is a special method of decorating the surface of printed matter. It uses a concave-convex mold to plastically deform the printed substrate under a certain pressure, and then artistically processes the surface of the printed matter. The various convex patterns and patterns of the embossed display different patterns of different shades, and have a distinct embossing feeling, which increases the overall three-dimensional sense and artistic appeal of the package.
Five, die-cutting indentation
Die-cutting indentation is also called press-cutting, knives and the like. When the package printing carton needs to be cut into a certain shape, it can be completed by a die-cutting indentation process. Die-cutting is a process in which a steel blade is arranged into a mold (or a steel plate is used to form a mold), a frame, etc., and the paper is rolled into a certain shape on a die-cutting machine, and the hollow portion of the main display surface is obtained by a die-cutting process. Personalized decoration throughout the package. The indentation is the use of a steel wire to emboss marks on the paper or leave a groove for bending.
Gold, silver, laser gold, bronze gold, etc., usually after the glue is hot stamped or silver; out of the film to have the alignment line; bronzing effect is diverse, but according to the substrate of hot stamping, sub-hot gold paper, hot Flannel of hot plastic and so on.
Seven, local UV process
It is a silk screen printing process that enhances the colorful effect of the package by partially applying UV varnish to the surface of the carton.
