Folio refers to the layout size and layout of books, magazines and other printed matter. The word folio is usually used in the printing and publishing industry to describe the specifications and styles of printed matter. According to the content, purpose and design requirements, the size and layout of folio can be adjusted. For the text of a book, the meaning of the folio number is the same as that of the folio number, but for the folio number of the cover and the insert, the meaning is different because of the different areas. The size of a one-page publication is usually called a folio.
Folio refers to the size of the book format, that is, how many pages are cut on a fully open printing paper. There are 32 folio (cut into 32 sheets, mostly used in general books), 16 folio (cut into 16 sheets, mostly used in magazines) and 64 folio (cut into 64 sheets, mostly used in small and medium-sized dictionaries and comics).
Format specification
In actual production, the whole paper with a width of 787× 1092 mm (3 1×43 inches) is usually called orthogonal paper. The width of the whole paper is 889× 1 194 mm (35×47 inches), which is called wide paper. Because the format of 787× 1092 mm paper is defined by China itself, it is inconsistent with international standards and belongs to non-standard format, which needs to be phased out. Due to many reasons such as domestic paper-making equipment, paper and existing paper types, there is still a transitional stage between the old and new standards.
The maximum size is 20 13, and the cutting specifications are: large 16 format 2 10×297(mm), large 32 format 148×2 10(mm), and large 64 format/kloc-. The correctness is: 16 folio 188×265(mm), 32 folio 130× 184(mm), and 64 folio 92× 126(mm).
