The cover is the main body of book design. When the book is put on the shelf, the first thing we see is the cover of the book, which is the facade of the book and the guide for readers.

2. Back shell

The back cover design is an extension of the cover design. Although it is difficult for readers to see at a glance, it conveys a lot of information, which is a powerful supplement to the cover content, including responsible editor, book box designer, bar code, book number, pricing, and sometimes content summary, author profile and publisher introduction.

3. Spine

The spine is the smallest part of the cover, and books that are too thin even have no spine. It is located between the front cover and the back cover, which can reflect the thickness of the book. Even on many occasions, books are placed upright on bookshelves, with only the spine facing outwards. At this time, the spine becomes the first part that readers come into contact with when choosing books.

Step 4 cut

The book is a hexahedron. Except for the front cover, back cover and spine, the other three faces are incisions, that is, the faces composed of the thickness of each paper in the book. These three faces need to be processed and cut together relative to the raw edges, hence the name.

5. Lekou

Necking, also called folding, is the part where the outer incision of the front cover and back cover of a book is folded inward. Usually, the width of the necking is 5- 10 cm, which can increase the thickness of the outer edge of the front cover and back cover, thus protecting the inner pages and corners of the book. There are two kinds of ties: front ties and back ties. The front tie is connected with the front cover, and the back tie is connected with the back cover.

6, protect the seal

The protective cover is another outer cover wrapped in the front cover and the back cover. First of all, it protects books from being damaged. Books may be damaged after repeated reading, and the protective cover can alleviate the damage to some extent; Second, it can play a decorative role. Generally, the cover is mostly used for hardcover books, using better quality paper).

7. Waist seal

The waist seal is the tape of a book, usually outside the cover of the book, and it is a paper tape with a width of one-third to one-fourth of the cover. The above is the summary of the book, or the recommendation of some famous people. From the design point of view, it is a prelude to the cover and can supplement the overall design of the book. Because the waist seal is mainly composed of characters, we should pay attention to the size, font and arrangement of characters when designing.
