With the development of the current society, people often use printing technology to help us print on book paper, and the printing technology is also different, so what are the common printing processes for book covers? The following is introduced by China Printing Company.

 

What are the common printing processes for book covers?

 

There are many printing processes for the cover, such as bronzing, embossing, laminating, oiling, UV, etc. This depends on the needs of your book. Book printing Sjinainvolves many aspects, such as the quality of its own design, the choice of paper, the size of the book, and the later process.

 

Several common processes in the cover of boek druk:

 

Bronzing / bronzing silver

 

Definition: hot press transfer printing, referred to as hot pad printing, commonly known as bronzing and silver bronzing. It is a method of hot-stamping the metal foil on the printed matter with the help of a certain pressure and temperature, and there is also a cold pad printing.

Features: It has metallic luster and magnificence, which makes the printed picture have a strong contrast.

Scope of application: suitable for very prominent text or logo, mostly used for samples, greeting cards, invitations, wall calendars, desk calendars, etc.

Note: It can be more pronounced with the embossing or embossing process; besides gold and silver, the colors that can be used include color gold, laser light, spot color, etc. to choose from.

 

UV-laag

 

UV stands for abbreviation, which means that the ink can be dried and cured by ultraviolet radiation. UV is usually a silk screen printing process, and now there is also offset printing UV.

Definition: a special process for curing the ultraviolet photoresist on the surface of the printed product in full or partially

Features: A variety of artistic special effects can be presented on the surface of the printed matter to make the printed matter more exquisite

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

Scope of application: book mounting, envelopes, covers, desk calendars, high-end packaging, handbags, etc.

Note: If you use UV on the film, you need to use a special UV film, otherwise the UV is easy to fall off, its bubbles, open glue and other phenomena, and the effect of special processes such as bumping and bronzing is better.

 

Embossing

 

Definition: Use the concave template (female template) to impress the surface of the printed matter into a concave relief-like pattern (the printed matter is partially recessed to make it three-dimensional and cause visual impact.) It is called indentation.

Features: can increase the three-dimensional feeling

Scope of application: suitable for paper of more than 200g, high-weight special paper with obvious sense of mechanism

Note: It is better to cooperate with hot stamping, local UV and other processes. If the concave template is heated and applied to special hot melt paper, it will achieve an extraordinary artistic effect.

 

Analysis of the types of post-processes for several book covers:

 

1. Hot stamping and hot stamping of silver, which is a method of hot stamping metal foil on printed matter with the help of a certain pressure and temperature. It is characterized by metallic luster, which makes the printed picture have a strong contrast. Commonly used are greeting cards, wall calendars, desk calendars, invitations, etc.

2. UV coating, which is a way of using ultraviolet radiation to dry and solidify the ink. Its characteristic is that it can present a variety of artistic special effects on the surface of the printed matter to make it more exquisite. Commonly used are high-end gift box packaging, handbags, envelopes and so on.

3. Indentation, the principle is to use the indentation template to emboss the surface of the printed matter into a relief-like pattern with a sense of depression through the action of pressure. It can effectively increase the three-dimensional feeling. It is worth noting that this late-stage process is only suitable for high-gram-weight special papers with obvious textures above 200g.

4. Convex, similar to embossing, embossing uses a convex template to emboss the surface of the printed matter into a three-dimensional relief-like pattern through the action of pressure. It can also increase the three-dimensional effect of printed matter. The applicable paper requirements are also the same as for embossing.

5. Embossing, the principle is to use the metal roller for engraving the texture to leave a full version of the texture on the paper after pressing. It is characterized by strong decorative lines and unique style. Commonly used are desk calendars, high-end packaging, handbags, etc.

6. Laminating, covering the surface of the printed matter with a plastic film and bonding them together after heating and pressing with an adhesive. Laminating film is divided into light film and dumb film. It is only suitable for paper above 200g.
