There are 4 page arrangement skills for book printing

generally, the folding of 16 folio book pages, especially the effective travel pages of the stretching machine and sample fixture, is three folio, and the duplicating page is two folio; 32. The folding of the pages of the folio book set is half fold, and the reproduction is half fold. For the coding process of books and periodicals with different specifications and sizes, the larger printing enterprises are arranged in detail by the production department and completed together with the completed printing construction sheet, while the page numbering of books and periodicals in small and medium-sized printing enterprises is generally completed by the direct operation of the plate making workshop. No matter who completes the page arrangement of books and periodicals, the following problems should be paid attention to when arranging the page numbers of books and periodicals

1. When arranging the pages of books and periodicals, we should first make clear the binding method of books and periodicals. Paperback binding, horse riding binding, hardcover sewing, adhesive binding, sewing machine sewing and other different binding methods are absolutely different in arranging the page numbers of books and periodicals. The page numbers of books and periodicals should be arranged according to their different binding methods. For example, the pages and their codes of 16 Kai horse binding books and periodicals and 16 Kai flat binding books and periodicals are different. Horse riding bookbinding is to fold all the pages of books and periodicals together, and then use the stapler to bind two iron nails at the middle book indulgence, while flat bookbinding is to separately arrange a stack of 16 folio three fold Book stickers folded according to the page number sequence, and then paste them into books in turn, and then put them flat on the stapler. 20. The weight of the main machine: 1250kg; Pack your luggage into a book

accurately calculate the page number of a book according to the publishing house's book printing layout sheet, and convert it into the number of printed pages. For example, 16 folio printing sheets are folded three times, and the front back overprint accounts for 16 pages; 16 folio printing, double folding, front and back reprinting, accounting for 8 pages; 32 folio printing sheets are folded in four, and the front and back overprint accounts for 32 pages; 32 folio printing, three fold, front and back copy, accounting for 16 pages. The total number of pages divided by the number of pages of each printed sheet equals the number of printed sheets

3. When arranging the pages of books and periodicals, we should grasp the influence of the thickness of the paper on the binding quality and page arrangement. For example, when printing 32 folio books and periodicals, the thin paper below 60g/m2 can be folded into four folio sheets; However, for 70g/m2, 80g/m2 and more than 60g/m2 book edition paper, offset paper, and even coated paper color pictorial, due to the thick paper, considering the requirements of printing, binding and other processes when arranging the page number, it is obviously impossible to fold the opening sheet four times. Even if it is reluctantly folded, the folded book has a thick spine, and the cut page code has a great error, which is wrong in the back of the pin clamp block, and the opening is inconsistent, affecting the beauty of the book, The printing and binding quality of books and periodicals is damaged. Therefore, for thick paper books and periodicals with more than 60g/m2, the folding times of books and periodicals should be reduced as much as possible when arranging the page numbers of books and periodicals, so as to control the thickness of books and periodicals, and avoid the deviation of page numbers of books and periodicals and the graphics and texts in the center of the page, which will affect the aesthetics

4. Experienced publishers and periodicals and magazines try to use integer printing sheets or add one and a half printing sheets when arranging the pages of books and periodicals, so as to facilitate the printing and binding of books and periodicals. However, in practical work, we often encounter the situation that the final remaining 0.75, 0.8, 0.9 and other printing sheets, so how to arrange the remaining sporadic printing sheets is the most appropriate? If the sporadic printed sheets are bound by paperback, binding, hardcover sewing and other binding methods, do not compile the remaining sporadic printed sheets to the end of a book. It is best to arrange the sporadic page numbers of less than one printed sheet in front of the last complete printed sheet, so as to prevent the failure of scattered pages and page loss caused by sporadic pages in the binding of books and periodicals. For the sporadic printing sheets or loose pages that are not enough for a book or periodical ordered on horseback, it is better to insert them into the middle of the book or periodical, so as to avoid the phenomenon of pages falling and scattering when the sporadic loose pages of the book or periodical are placed at the spine of the subscription mouth
