Updated: 01-04-2024

1.Lamination process

Definition: A processing technology that covers the surface of a printed matter with a plastic film and uses an adhesive to bond it together after being heated and pressurized to form a paper-plastic printed matter.

Classification: There are two types of coating: spectroscopic film and matte film.

Features: The surface of products covered with glossy film is bright and expressive, and is mostly used for product prints; the surface of products covered with matte film is non-reflective, elegant, and is mostly used for image prints.

2.Hot stamping process

Definition: Hot stamping uses the principle of hot pressure transfer to transfer the aluminum layer in anodized aluminum to the surface of the substrate to form a special metallic effect. Since the main material used for hot stamping is anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping.

Features: The hot stamping pattern is clear and beautiful, and the colors are bright and eye-catching.

Scope of application: foil stamping on packaging boxes, foil stamping on trademarks and boxes of tobacco, wine, and clothing, foil stamping on book covers, foil stamping on greeting cards, invitations, pens, etc.

3.Glazing process

Definition: A process in which a layer of colorless and transparent paint is applied (or sprayed or printed) on the surface of a printed matter, and a thin and even transparent bright layer is formed on the surface of the printed matter after leveling, drying, calendering and solidification. This process is called coating. Light craft.

Features: Glazing can not only enhance the bright surface gloss, but also play a role in waterproofing and oil-proofing the surface of the packaging, protecting printed graphics and text, and does not affect the recycling and reuse of paper.

Scope of application: surface processing of packaging cartons, books, albums, posters and other printed products.

4.Embossed process

Definition: Concave and convex embossing is a special method of decorating the surface of printed matter. It uses a concave and convex mold to plastically deform the printed matter substrate under a certain pressure, thereby performing artistic processing on the printed matter surface.

Classification: cheap ordinary etched version and expensive laser engraving version.

Features: Various embossed convex graphics and patterns show patterns of different shades, with an obvious sense of relief, which increases the three-dimensional sense and artistic appeal of the printed matter.

5.Die cutting and creasing

Definition: Die-cutting and creasing is a process in which steel knives and steel wires are arranged into a template, and the printed matter is processed into the required shape under pressure.


Classification: Die-cutting is a process of cutting paper into a certain shape on a die-cutting machine. Indentation is the use of steel wire to press out marks or leave grooves for bending on the paper.

Features: Can produce special shapes and enhance expression.

6.Local UV process

Definition: It is a silk screen printing process that partially applies UV varnish to the surface of the carton to enhance the colorful effect of the printed product.

Features: It can present a variety of artistic special effects on the surface of printed matter, making the printed matter more beautiful.

Types: thickened UV, frosted UV, colorful UV, glass beads, sprinkled with colorful powder, etc.

Scope of application: packaging boxes, book and periodical mounting, envelopes, covers, desk calendars, handbags, etc.

7.Reverse lighting

Definition: The working principle of the reverse glazing process is to use the "mutually exclusive" principle of coating type UV varnish and underprinting UV varnish (ink fountain type UV varnish) to achieve the effect of concave and convex texture and different gloss at one time, that is, in Apply varnish to areas without base oil to achieve a glossy effect, and apply varnish to areas with base oil to achieve a matte effect.

Classification: The surface of the printed product forms local high-gloss and local frosted low-gloss areas.

Features: Two completely different gloss effects achieve a high-contrast effect on local images, embellishing and highlighting graphics and texts with glossy mirror surfaces.


8.Hot stamping and embossing in one

Definition: A hot stamping method with a stronger metallic and three-dimensional effect is shown through changes in the hot stamping version. Through the concave and convex changes of the relief pattern, the graphics and text present a metal relief-like texture, making the hot stamping graphics and text jump out of the plane, bringing a stronger visual impact.

9.Laser Imprint Transfer

Definition: After coating the surface of the printed product with UV varnish, it enters the imprinting system, the printed product and the laser transfer film are combined together, and then it is instantly cured by UV light irradiation. Finally, the printed product and the laser transfer film are peeled off to make the laser transfer film The laser pattern on the surface is transferred to the printed product.

Features: It makes printed products have dazzling visual effects, can effectively improve the quality of packaging, and is degradable, recyclable, and easy to handle. It is a high-end printing material that is anti-counterfeiting and environmentally friendly.

Scope of application: cosmetic packaging, wine box packaging, pharmaceutical packaging, gift box packaging, cigarette packaging.

10.freezing snowflakes

Definition: Freezing point snowflake is a kind of fine sandy texture formed on the surface of the printed matter after the ink is screen-printed on gold cardboard, silver cardboard, laser cardboard, PVC and other substrates, wrinkled by UV light and cured by UV light. Craftsmanship with a delicate touch.

Features: fine patterns, strong three-dimensional effect, luxurious and elegant.

Scope of application: tobacco and wine boxes, wall calendars, gift box packaging or other exquisite prints.
