What are the commonly used printing techniques for books that you know?

Today, we have compiled 9 commonly used book printing processes, including hot stamping, laser hot stamping, laminating, die-cutting, local UV, embossing, embossing, edge brushing, and laser hollowing. Let‘s take a look together!

1. Stamping process

The hot stamping process utilizes the principle of hot press transfer to transfer the aluminum layer from anodized aluminum to the surface of the substrate to form a special metal effect. As the main material used for hot stamping is anodized aluminum foil, hot stamping is also known as anodized hot stamping.

The metallic luster of hot stamping has a strong decorative effect and visual impact.

2. Laser hot stamping

Laser hot stamping is a process that utilizes the effect of temperature and pressure to transfer the laser pattern on the anodized aluminum to the substrate.

The characteristic of laser hot stamping process is that the brush can present different colors with changes in observation angle, with a significant dynamic color change effect, and can produce a rainbow ring effect under concentrated light.

3. Film coating process

Lamination, also known as overgluing, has a strong protective effect on the printing color, avoiding scratches and enhancing the toughness of the printed product. The book cover after lamination has a smooth and bright surface.

According to the different film materials, it can be divided into glossy film, matte film, pearlescent film, and tactile film.

4. Die cutting process

Usually, the die-cutting process involves combining the die-cutting knife and the wire pressing knife into the same template to perform shape excavation treatment on the material.

Die cutting allows various printing packaging to be presented in three-dimensional and curved shapes, creating a variety of shapes and shapes that are more beautiful and exquisite, full of creativity.

5. Local UV

UV technology is the use of UV ink to cover the surface of printed materials, producing different bright effects, and is widely used in book design and production.

The UV process makes the printed parts appear high in brightness, transparency, and wear resistance. The surface of printed materials that have undergone local UV treatment has a more textured and three-dimensional feel, highlighting the visual effect of local bright light.

6. Indentation process

The embossing process is the use of concave and convex molds to perform artistic processing on the surface of printed materials. Applying pressure from the front of the paper to make the surface concave is called "indentation". Embossing is the use of a single metal plate to press the graphic and textual content of thicker paper into it, creating a unique concave feel.

This craft image and text have a clear three-dimensional sense, adding artistic appeal to the book.

7. Punching process

The embossing process is one of the commonly used techniques in the post printing process. The process of applying pressure from the back of the paper to cause the surface to swell is commonly known as "embossing"; The purpose of this process is to increase the sense of hierarchy in the overall structure.

The raised text on the cover of the picture uses the plain embossing printing process, which can present the raised graphics or text with a unique embossing process in a delicate, neat, and clean manner.

8. Brushing process

Brushing edge technology is the use of manual or digital technology to print different colors or images and texts on the side of a book at the opening.

The edge brushing process includes: 1. Rolling the golden edge refers to hot stamping various colors on the side; 2. Spray color; 3. Silk screen printing (with color on the side, including colorful patterns) The book‘s opening in the picture uses silk screen technology., It can enhance the uniqueness of books.

9. Laser hollowing out

Laser hollowing is the use of the high energy density characteristics of lasers to irradiate the surface of products, cut through the processed products, and produce a certain hollowing pattern effect.

The precision of traditional post press processing for circular or right angle die-cutting is limited, while using laser engraving can achieve many special shapes and greatly improve the accuracy of the product. Laser hollowing fills the print with an artistic sense.
