Gold and silver inks are simply called gold or silver. They are metallic inks, which are characterized by noble elegance, saturated colors, and a wide range of applications. There are two main types of gold and silver inks: pigments (colors) and binders (adjusting oils).

To judge the quality of the packing carton, we need to observe the material of the packing carton, the different quality of the packing carton, the material used feels different, we can observe from the outside whether the material is cloudy, the material with Sundries, or relatively clean, with a stronger texture, we can see.

Film is a direct transliteration of "FILM" in English. The common name for film in the platemaking and output center is actually a transparent film. There is a medicine film on one side of the film. Pay attention to protect this side to avoid scratching, and there is no medicine film on the other. The printed film is divided into four colors (CMYK) and spot colors. The four color films are stacked to form a complete color image, and the spot color films are usually made into black plates for printing suppliers to make PS plates.

A lot of people think corrugated box is paper products, production must consume a lot of wood, so feel corrugated box is not a green packaging. Actually is not like this, the corrugated box is indeed a kind of environmental protection packing material. Today, corrugated box manufacturers Wenwei packaging to give you an analysis, why corrugated box is a green packaging.

Because the main raw material of spot color printing gold ink is brass powder, it is a chemically active metal, which is prone to discoloration after exposure to air. Therefore, we should pay attention to the following situations when printing gold ink:

1.Box Shape: in the case of manufacturing, some customers like to make a variety of strange shapes, with boxy appearance, the strength of this kind of box will be reduced, in general, the supporting strength of the box is also relatively large in the box four edges and adjacent edge of the side, here can bear a lot of external thrust. In addition, a layer, the longer the box diameter, height-to-width ratio, the lower the strength of the box.

According to the design requirements, specific paper and materials are processed and manufactured on a machine equipped with a steel knife stencil, and the paper or material is die-cut into the required shape and presents special effects in form. Such a process technology is called die cutting. The specific paper and materials are processed and manufactured on a machine equipped with a steel wire template according to the design requirements. The surface of the paper or material is printed with deep or shallow steel wire traces under pressure, and then folded by hand or machine. The paper And materials are easy to bend and form a certain form of structure or shape. Such a process technique is called indentation.

Post-print processing of printed materials mainly refers to surface finishing, binding technology, and other processing methods to improve the pressure resistance, water resistance, and sealing or environmental protection performance of printed materials. The post-printing process in the industry refers to the surface decoration of printed matter as the main direction. Generally speaking, the post-printing process (hereinafter referred to as the printing process or process) mainly refers to a series of processing steps after the substrate is printed. It includes Die Cutting, embossing, embossing, creasing, bronzing, laminating, folding, punching, glazing, laminating, die cutting, binding, packaging, etc.

Hot stamping aluminum is also called "hot stamping", "hot stamping foil" or "hot stamping", etc. According to different printing materials, it can be divided into paper stamping, fabric stamping, leather stamping, and plastic stamping. According to different hot stamping templates and process technologies, there are hot stamping, cold stamping, single layer stamping, multiple stamping, and three-dimensional stamping.
