Twelve kinds of paper cosmetic boxes post-press processes, how much do you know?

The post-press process of paper cosmetic boxes refers to the processing of the printed product after it is completed. Surface processing is to improve the appearance and quality of the cosmetic boxes, mainly including lamination, and the main processes are concave and convex embossing, die-cutting indentation and other processing technologies.

1. Coating

The lamination is a transparent plastic film that is pasted to the surface of the printed matter by hot pressing, which is smoother and brighter, and the color of the graphics and text is more vivid. Waxing and other processing technology; molding processing technology. The film can make the surface of the printed matter wear-resistant, fold-resistant and chemical-resistant. However, since the plastic film is not degradable, it is difficult to recycle and easily cause pollution. Therefore, the plastic lamination process should be used with caution when glazing can be replaced.

2. Hot stamping

Hot stamping, also known as hot pressing printing, is to make the pattern or text that needs hot stamping into a relief version, and with the help of a certain pressure and temperature, various aluminum foils are printed on the substrate, showing a strong metallic light. , so that the product has a high-grade texture. At the same time, due to the excellent physical and chemical properties of aluminum foil, it can protect the printed matter. Therefore, the hot stamping process is widely used in modern packaging printing.

3. Glazing and waxing

Glazing is to coat or spray a layer of colorless transparent paint on the surface of the printed matter, brush the gloss of the product, and play the role of waterproof and oil-proof on the surface of the package. The product has bright luster and plays a good barrier effect. To make it form a glossy film to increase the printing wax is to apply hot melt wax on the wrapping paper.

4. Concave and convex embossing

Embossing is a special technique for decorating the surface of printed matter. It uses a concave-convex mold to plastically deform the substrate of the printed matter under a certain pressure, and then perform artistic processing on the surface of the printed matter. The embossed various convex graphics and patterns show different shades of patterns, with an obvious sense of relief, which increases the three-dimensional sense and artistic appeal of the printed matter.

5. Die-cutting indentation

Die-cutting indentation is also known as press-cutting molding, buckle knife, etc. When the packaging and printing carton needs to be cut into a certain shape, it can be done by die-cutting and creasing process. Die-cutting is a process of arranging steel blades into a die (or carving a die with a steel plate), a frame, etc., and rolling the paper into a certain shape on a die-cutting machine. The hollow part of the main display surface in the middle is obtained by the die-cutting process. Personalized decoration throughout the package. Indentation is the use of steel wire to press out marks or leave grooves for bending on the paper by embossing.

Six, bronzing

Gold, silver, laser gold, bronze gold, etc., generally hot stamping or silver is only after the glue has passed; the film must have an alignment line; the hot stamping effect is various, but it is also classified according to the base material of the hot stamping, which is divided into hot stamping paper and hot stamping. Flannel hot plastic and so on.

Seven, local UV process

It is a silk-screen printing process that enhances the dazzling effect of printed products by partially coating UV varnish on the surface of the carton.

Eight, freezing point snowflakes

The freezing point snowflake effect is a kind of fine sand and hand feeling formed on the surface of the printed product after the ink screen printing on gold cardboard, silver cardboard, laser cardboard, PVC and other substrates is wrinkled by ultraviolet light and cured by UV light. Subtle effect. Because of its appearance like a thin layer of snow or ice on the surface of the printed product, it is commonly known as "snowflake" (larger pattern) or "freezing point" (smaller pattern) in the industry. This process has the characteristics of fine pattern, strong three-dimensional effect, luxurious and elegant visual, and is widely used in tobacco and alcohol boxes, calendars, gift box packaging or other exquisite printed products.

Nine, reverse frosting

The reverse frosting process is a new type of printing process that has appeared in the past one or two years. It needs to be processed through several special primers or varnishes. A new craft of light. This process is to print the printed product according to the normal color sequence, after the ink is completely dried or cured, a layer of special primer is printed on the local area that does not need to highlight high brightness by offset printing connection (or offline). After the primer is completely dry, apply UV varnish to the entire surface of the printed matter in a full-plate manner. In this way, a cohesive reaction occurs in the contact area between the UV varnish and the primer to form a small granular ink film, which constitutes a matte or frosted matte surface; and a high-gloss mirror surface is formed in the UV varnish area where the primer is not printed. Eventually, localized high-gloss and localized matte low-gloss areas are formed on the surface of the print. Two completely different gloss effects achieve a high-contrast effect of partial images, embellishing and accentuating graphics with a glossy mirror finish.

10. Embossed bronzing

This process is a bronzing method that shows a stronger metallic and three-dimensional sense through the change of the bronzing version. Through the concave and convex changes of the embossed pattern, the graphics and texts present a texture like metal embossing, so that the bronzing graphics and texts jump out of the plane, bringing a stronger visual impact.

11. Laser Transfer

It has dazzling visual effects, which can effectively improve the quality of packaging. This process can print full-page or partial transparent laser effects on ordinary paper with smooth surface, which has changed the previous only using laser paper for printing, or printing on paper. Only the special laser film on the surface can show the processing method of the laser effect, and the laser pattern can be flexible and changeable.

12. Photolithography paper

A paper material with a very high technical content, which integrates advanced technologies such as local embossing, holographic laser anti-counterfeiting, vacuum aluminum plating, paper-plastic composite slitting, and nest printing, which has changed the previous situation of single laser grain effect, and the paper is gorgeous and dazzling. The unique visual effect, coupled with the unique anti-counterfeiting function, not only cannot be copied and plagiarized, but also facilitates consumers to intuitively identify authenticity.
