3. Line fitting
It is one of the methods of book binding. Its obvious feature is that the bound lines are exposed outside the book. Thread binding is a traditional binding method in China, which is relative to the introduction of foreign "clothing" books. When binding, the printed pages are folded according to the middle seam, so that the book mouth is aligned, and the cover, back cover, punching and threading are carried out. Thread-bound books should only use soft cover, and each volume should not be too thick, so one volume of thread-bound books is often divided into several volumes and dozens.
Therefore, people add a letter (book cover made of hard paper and cloth) to each volume of books, or bind them with threads and ropes from upper and lower boards to protect books. Thread-bound books prevailed after Wanli in Ming Dynasty. It is developed from butterfly skirt and wrap skirt.
The difference between paperback and hardcover of extended materials;
The production of a book includes two parts: printing and binding. For hardcover books and paperbacks, the printing process is the same, and there is no difference. It's just that hardcover books require better quality, so the paper used is generally better (for example, thicker and more upscale), while paperback books can use ordinary paper.
Then, in the printing process, the printer will pay special attention to the printing quality of hardcover books, and will pay special attention to quality control, such as color difference, overprint, dirty spot control and so on. Paperback books can be printed according to general quality standards.
The main difference between hardcover books and paperback books is binding. Paperback books are the books we usually use, such as textbooks. Generally, the binding process is adopted, that is, the inner pages of the book are glued together with special glue, and then glued together with the cover. Usually use a special binding machine.
The cover is plain coated paper, which is thicker than the inner page. The whole book can be bent and held in your hand. The inner pages of hardcover books generally adopt thread-locking technology, that is, the inner pages are locked together with thread, and then glued together, which is relatively firm and does not like to drop pages. The cover is usually cardboard, and beautifully printed tissue paper is pasted on the cardboard to form the book cover, and then the inner pages are glued to the book shell.
