1. When formatting the pages of a book, you must first clarify the binding of the books. Flat binding, saddle stitching, hardcover lock stitching, glue binding, sewing seams and other various binding methods, which are absolutely different in the layout of the book page number, according to their different binding methods to arrange the book page number. For example, books with 16 horseback riding books and 16 books with open bound books and their codes are all different. The saddle stitching stacks up all the book pages, and then staples two staples at the middle spine, and the flat binding folds a stack of 16 open three-fold books in order of page number. The placards are arranged separately, and then the placards are put into books, and then they are placed flat on the stapler for binding.

2. Prior to the layout of the page number, the Printing House Production Division has to accurately calculate how many pages of a book are printed according to the book printing and dispatching orders of the publishing house and is converted into the number of printed pages. For example, a 16-fold open-sheet is folded, a front-to-back version takes up 16 pages, a 16-fold is open for two-fold, and a front-back version is used for 8 pages. A 32-fold split is a 4-fold offset, and a positive back version takes 32 pages. ;32 open off the printed sheet tri fold, is back to copy version accounted for 16 pages. The total number of pages divided by the number of pages per sheet is equal to the number of sheets.

3. When formatting the pages of books and periodicals, you should master the effect of the thickness of the books and papers on the quality of binding and the arrangement of page numbers. Such as printing 32 specifications of books, 60g/m2 below the thin paper can be folded off 40 percent off; and 60g/m2 of 70g/m2, 80g/m2 of the book paper, offset paper, and even the colorful art of coated paper Due to the fact that the paper is thicker, the layout of the page number takes into account the requirements of printing, binding, and other processes, and it is obviously not feasible to open four-fold printed sheets. Even if it is reluctantly folded, the folded back has a thick back, and the page number error of the trimmed page is too large. Very large, staggered inconsistencies before and after, affecting the beauty of books and publications, so that books and magazines are bound to impair the quality of printing and binding. Therefore, for thick paper publications of 60g/m2 or more, the number of folds of the signature should be reduced as much as possible in order to control the thickness of the signatures, and the offset of the page number and edition of the publication should be avoided to affect the appearance.

4. Experienced publishers and periodicals and magazines should use as many as possible whole-page prints or a half-page print when arranging the pages of a book to facilitate book binding. However, in the actual work, it is often the case that the last remaining 0.75, 0.8, 0.9, etc. sheets are printed. What is the most appropriate way to arrange the remaining sporadic printed sheets? If the sporadic printed sheets are bound by paperback, perfect binding, or hardcover binding, do not arrange the remaining sporadic copies to the end of a book. It is advisable to arrange the sporadic pages of one print less than the last full print. In the front, this can prevent books and magazines from being sporadic because they have sporadic pages that cause page breaks and page breaks. It is better to insert a sporadic printed sheet or loose leaflet that is not enough for a saddle-stitch book and periodical into the center of the book, so as to avoid the appearance of page breaks, loose leaflets, etc. at the book's spine.

5. The written handwriting is required to clear the written handwriting, making it easy for the imposition operator to read it clearly. For each printed sheet and a piece of printed sheet that is not enough for one sheet, after the stacking, it must be written on the first page of the printed sheet to clear the page number sequence number, book name, etc., if the page number compilation encounters the table of contents, the preface, the inscription, the advertisement, and the editor. Press, preface, etc., must be clearly written and detailed in the specific position of the layout page number, so as to avoid the imposition of errors, errors and so on.

6. During offset printing, it is necessary to install a book version on the plate cylinder, adjust the machine, and leave space for books, magazines, feet, cuts, etc., and compare the edited page number with proofing proofs to eliminate Mistakes caused by imposition, reversal, etc. caused by the printing quality accidents. At the time of binding, the pages of the book must be strictly sorted according to the pages of the book.
