Saddle stitching hardcover locking sequence perfect binding Sewing machine seams and other different binding methods, these are completely different when formatting the pages, (SZ printing factory) arrange the books according to the page number of different binding methods.
When formatting pages, we must first figure out how to bind the book.
pop up book wholesale Before arranging the pages of the book, the printing department of the printing house should accurately calculate the number of pages of the book according to the printing list of the publishing house and convert it to the number of printed pages.
For example, 16 pairs of open paper and 30 folds, the front and back versions account for 16 pages; 16 pairs of open sheets with two folds, front back version accounting for 8 pages; Fold open 32 pairs of printed paper and set the front back to 32 pages. 32 Print Print on three sides, front and back version takes up 16 pages. The total number of pages divided by the number of pages per sheet equals the number of sheets.
When editing the page number of a book, you should understand the effect of the thinness of the book and paper on the quality of the binding and the page number.
For example, if you print 32 pages of books, 60 g/m2 or less of paper towels can be folded and folded four times, 70 g/m2 of 80 g/m2 of book paper offset paper 60 g/m2 or more, or even coated colored paper. Due to the thick paper, the page numbering takes into account the requirements of printing and binding. Apparently it is impossible to open the printed paper, even if it is hardly folded, the folded signature is very thick, and the corrected page number error it is very large, inconsistent, affecting the beauty of the books and magazines, and the quality of the book printing and binding is impaired.
Therefore, for heavy paper books of 60g/m2 or higher, the number of folds of signatures must be minimized when formatting book pages to control the thickness of signatures and avoid offsets between page numbers. And the layout of the book affects the appearance.
Four experienced publishers, journals and magazines should use integer printing whenever possible when arranging books and pages, or add semi-printing to facilitate the printing and binding of books. However, in actual work, you often encounter the last remaining 0.75, 0.8, 0.9, etc., so how to arrange the remaining sporadic printing paper is the most appropriate? If sporadic worksheets are constrained by paperwork and hardcover lines, do not put the remaining sporadic worksheets at the end of the book. It is best to arrange scattered page numbers of a piece of paper in the last complete table. Previously, this prevents issues such as page loosens and page drops due to scattered pages during book binding.
It is best to insert a scattered sheet of printer paper or a loose sheet of printer paper in the middle of the book, so as to avoid the scattered pages of the book resting on the spine while the pages are scattered.
pop up book wholesale, you should install the book version on the plate roller, adjust the machine, and leave the book position foot cut, etc. You need to compare the compiled page number with the proof page to eliminate proof that the collage misalignment reversed the book printing quality accident caused by the reverse. When binding, you must also strictly match the pages according to the compiled pages and bind them to the book.
pop up book wholesale When writing page numbers, it is required to write clearly and be easy for the collage operator to read. For each printed paper, and for sporadic printed paper (less than one printed paper) must be written on the first page of the printed paper, the page number is etc., if the page number meets the table of contents, preamble, inscription, advertisement, editor's note preface, etc., must be clearly marked in the specific position of the page number, so as not to miss errors.
