Classification of books and printed products and structure of books (on)

First, the classification of books and printed products

According to the classification method of CY1-91, the industry standard of the People's Republic of China for the classification of books and printed products, the printed products of books and periodicals are divided into books, periodicals, newspapers and other products in the form of their final products.

books. Refers to publications such as books and albums. Books are knowledge recorded in certain materials by words, drawings, and other symbols; they are non-regular publications that can clearly express certain thoughts and make books. It is an important tool for promoting social, political, economic, and cultural development, spreading knowledge, science and technology, and preserving human culture. Books are one of the important symbols of human progress and civilization.

Journals. The journal is commonly known as the magazine. It is a periodic or periodical serial publication in chronological or chronological order. Journals have fixed binding forms, layouts, columns, and names, and have fixed and open lines and periods, and thus have little impact on the organization of the binding production process.

The first appearance image that the book shows to the reader is the open book. The open book refers to the size of the book format, which means the finished product size of the book. It is usually expressed as a fraction of the area of ​​a single sheet of paper. For example, an open book for a common book is 32 shots, which means that the single-sided area of ​​a book is equivalent to 32 points of a full sheet of paper. In the past, the size of the commonly used sheet-fed printing paper was 787×1092mm and 850×1168mm. Because the format of the printing paper has sizes and sizes, the sizes of the books and magazines are also different from each other. It is customary to call the size of the 787×1092mm paper web series a small copy and the size of the 850×1168mm paper web series. Large format. There is still a certain distance between the open size and international standards. In order to catch up with the international standards for the cost of books and periodicals in China, in 1987, China established the national standard “Book and magazine size and format size”, codenamed GB788-87, and the standard sizes of the standard books and periodicals are shown in Table 1-1. .

In Table 1-1, A and B indicate the symbols of the open size series, and the numbers behind A and B indicate the number of times the full-length paper is folded in the long side, which is used as the transition size. The series of 787×1092mm can still be used 2000 years ago. Use, but to phase out. In order to further integrate with international standards and meet the needs of the rapid development of printing equipment, materials and technology, in May 2000, the new National Standard for Open Book and Size of Books and Magazines was revised and implemented, code-named GB/T788-1999. . According to this standard, the standard open size of books and magazines is shown in Table 1-2.

The sub-cut is 32 open, M indicates that the paper's turn direction is parallel to the size side. The revised standard eliminated the 787×1092mm paper.
