According to different thicknesses and special needs, the binding methods of propaganda albums include: saddle stitch, wireless plastic binding, and thread-locking plastic binding. The following is an introduction to the common printing and binding methods of picture albums:
1. Saddle stitching
In English, it means saddle. When binding, the folded page acts as a saddle on a horse and is attached to the chain of the binding machine. After binding, the nails are fixed on the horse’s back. Therefore, when you open the book and look at the middle part, you can find that the whole book is centered on the middle nail, the first page and the last page of the whole book are connected symmetrically, and the middle two pages are also symmetrical and connected around it.
1) Because of the center-centered symmetry of saddle stitching, the imposition is different from the ordinary flat binding, perfect binding, threaded paperback or hardcover when making a plate. Therefore, when designing a book, it is intended to be flat-bound. If you want to change the saddle stitching and imposition method after plate making, it is completely different, and the change is equivalent to redoing.
2) The page number must be divisible by 4, generally 8 pages, 16 pages, and no more than 64 pages at most. Pay attention to the amount of crawling if the page number exceeds 32 pages.
2. Wireless glue loading
Wireless binding refers to a binding method in which each page of a printed product is fixed on the spine with glue. It does not use iron wire or thread, but uses glue to bond the book block, which is a binding method from book publishing to automatic completion. The process flow is roughly as follows: page collation, book entry, back milling, roughening, upper side glue, book back glue, cover, molding, glue cooling, duplex, slitting, cutting finished product, stacking light book, inspection Finished product, strapping.
Wireless binding is one of the most commonly used binding methods. It consists of a product made by solidifying loose paper on the spine of a book through hot melt glue. It is suitable for general documents, bidding documents, materials, teaching materials, etc.
3. Locking plastic assembly
Thread-locking plastic binding, also called cross-threading plastic binding, after folding the page. It refers to a binding method in which the pages are threaded together with thread, and then the pages of the printed product are fixed on the spine of the book with glue. The advantage of the lock-threaded plastic binding is that the book block is glued together with a thread to fix it. When the book is opened, the content of the book can be fully displayed, from the book publishing to the automatic binding method.
Locking plastic binding is a very firm binding method, the cost and thickness are not limited, but after all, it is complicated, the production cycle is long, and the cost is high. It is suitable for large printing and binding enterprises.
