Book printing page number layout attention problem

1. When formatting a book page, first make sure that the book is bound. Flat binding, saddle stitching, hardcover lock binding, glue binding, sewing machine seams and other different binding methods, which are absolutely different when formatting the pages of the book, according to their different binding methods to arrange the book page number. For example, 16 pages of saddle-stitched books and 16-page bookbinding books and their codes are different. The saddle stitching is to stack all the books and pages together, and then use the stapler to place two nails at the middle spine, and the flat binding is a stack of 16 open and three folds in the order of page numbers. The posts are arranged separately, and then they are matched into a book, and then placed flat on the stapler for binding.

2. Before the page number of the book is arranged, the printing department of the printing house shall accurately calculate how many pages of a book are based on the printed list of the publishing house, and convert it into the number of printed sheets. For example, 16 pairs of open sheets and 30 folds, the front back version accounts for 16 pages; 16 pairs of open sheets are folded, and the front back version takes 8 pages; 32 open and close sheets are folded, and the back packs account for 32 pages. 32 open three folds on the opposite side of the print, the front back 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 compiling the page number of the book, you should grasp the influence of the thinness of the book and the paper on the binding quality and page numbering. For example, if a book with 32 specifications is printed, a tissue of 60g/m2 or less can be folded and folded four times, and a color of 70g/m2, 80g/m2 of book paper, offset paper or even coated paper of 60g/m2 or more. Due to the thick paper, the page number is taken into account when printing, binding and other processes are required. It is obviously not possible to open a four-fold copy. Even if it is barely folded, the folded signature is thick and the cut page number error Very large, inconsistent between before and after, affecting the beauty of books and magazines, and impairing the quality of book printing and binding. Therefore, for thick paper books of 60g/m2 or above, in order to reduce the number of folds of the signatures in order to control the page number of the books, the thickness of the signatures can be controlled to avoid the offset between the page number and the layout of the book, which affects the appearance.

4. Experienced publishers and journals and magazines should use integer prints or one and a half prints when arranging book pages to facilitate bookbinding. However, in the actual work, you will often encounter the last remaining 0.75, 0.8, 0.9 and other printed sheets, so how to arrange the remaining sporadic printed sheets is the most appropriate? If the sporadic printed sheets are in the form of paperback, perfect binding, hard-locking, etc., do not put the remaining scattered prints at the end of a book. It is best to arrange the scattered page numbers of one printed sheet in the last complete printed sheet. In the front, this can prevent problems such as loose pages and dropped pages due to sporadic pages when books are bound. For a saddle-stitched book that is not enough for a printed sheet of scattered paper or loose leaf, it is better to insert it into the middle of the book, so as to avoid the phenomenon that the scattered pages of the book are placed on the ridge of the book and the pages are scattered.

5. When writing the page number of the book, it is required to have clear handwriting, which is easy for the imposition operator to read clearly. For each sheet, and a sporadic sheet of paper that is not enough for a sheet, after the unstack, be sure to write the page number sequence number, title, etc. on the first page of the sheet, if the page number encounters the catalog, foreword, inscription, advertisement, editor According to the preface, etc., it is necessary to mark clearly and informatively at the specific position of the page number, so as to avoid flaws and errors in the imposition.

6. When printing offset printing, it is necessary to install the book version on the plate cylinder, adjust the machine, and leave the position of the book, the foot, the incision, etc., and compare the compiled page number with the proof sheet to eliminate the proof. The quality of book printing quality caused by misplacement, inversion, etc. When binding, we must also strictly match the pages according to the compiled book pages and bind them into a book.
