Book printing and binding mode of technologyBook printing and binding mode of technology
1. Fifty years on behalf of the bookbinding industry, the adjustment
Fifty years on behalf of the former, in the book printing industry, most technologically backward, the largest proportion of manual work is the binding. In the binding process, in addition to foot stapler, hand-cut the book to move beyond the use of machinery, the rest of the fold, with software, and brush glue, threading, package cover and other operations, no not the manual work. In some remote cities, and some binding also use machetes trimmer, awl drilling and hammer stapler. Because binding equipment operating in relatively poor, so bookbinding produced mostly scattered in small-scale hand-Zhuangding Chang, conducted a small workshop-style.
Binding is an indispensable book a production process, its production must be balanced with the print production. The early fifties, and Publication Administration in order to coordinate the development of book printing industry, so that books and printing, typesetting, printing, binding simultaneous development, the structure of books and printing industry to re-adjusted some of the small scale of the binding workshop merged into the scale of large professional Zhuangding Chang, or merge with the books and printing where a printing bookbinding workshop. Especially through public-private partnership since 1956, these small-scale Zhuangding Chang have been a merger or acquisition. In Shanghai, for example, in 1949 binding factory 130 in size,
In 1956 merged into 24 books Zhuangding Chang. With Shanghai in other cities similar to that after the early fifties, medium-term industry adjustment, all of the books are basically printers are configured to have binding workshop. Beijing-based Dragon Gate has always had a certain Zhuangding Chang, still preserved, after the further development of a specialized system of factory in Beijing.
2. Paperback and hardcover books printingBook binding, in short, sub-books and book exterior body of the core of the set together two aspects. Book exterior body of the book in order to protect the core, in order to form beautiful measures taken, such as the package cover, fitted book case, intensive care letters, cutting edge book, etc.; the book together is the core of the set loose in order to bring the book quote join a book core, easy to save and read. The body of the book sub-paperback and hardcover exterior two categories.
(1) Paperback
Is a book binding techniques binding of the more popular manner. It is relatively simple process, using fewer materials, low cost, suitable for circulation of the larger popular books, textbooks, children's books and so on. Paperback process: folding with quote → → → stapler pin plastic backs → compaction → package covers, hot back → crop.
(2) hardcover
For the important classics, academic works, important historical materials, pictures, Atlas, tools and books to use more hardcover. Hardcover books have a hard shell, and some even care letters, the book has a good protective effect of the core. Hardcover stress due to the use of materials, process complexity, so the cost of hardcover books to be higher than the paperback book. Fine hardcover books already, and for some books, in order to increase its value to the collection, or even luxury fitted, not only binding and beautifully designed, binding and even more excellent material. Need for the book but this is very rare.
Hardcover book, the general process in four phases:
Core set the book together: folding → → threading with quote compaction → → → Cutting the book back plastic core processing: a round back from spinal → → → paste plug paste gauze cloth → paste cardboard book case processing: The next material → brush Gum paste fabric → → → drying a letter to the shell package corner: complete sets of pressure tank shell → → → paste ring lining compaction → stereotypes
Book together and book-shell core set can be separately processed in parallel. When the book-core processing is completed, then processing of a good book in the book and core-shell units, further processing of stereotypes.
3. The book provides the core technology, the evolution of joint
Binding technological progress, mainly around the core of the book provides the development of joint manner. Core book link is as follows:
(1) 3 set
Quote in the book's set near the entrance to play three set eyes, eyes set with the line through the book quote book connecting core.
3 set on the old-fashioned method of manual stapler, the production efficiency is low. After the hard core turned the book are folded down, the rarely used since the fifties.
(2) wire-ping set
After the three set out, and in the quote set the mouth with wire stapler the book quote book linking the core. Connected with wire, book a solid core, high production efficiency, with the three set out, like the book after the hard core turned smoothing, wire easy to rust contamination of Book.
(3) threading set
For the book block in the 200-page book can still be below the level set with the wire, but for the core thick book of books, you must use threading set. Quote the book in order according to page numbers in the set mouth set into a book with the line string core. Threading set of Book advantage is that no matter how thick, and are available on-line wear set, and the book spread out after the core, arbitrary turn, can be shared flat. Threading is not a set of new technologies. Just before the hand threading the fifties, sixties after, and eventually the use of the stringing machine.
(4) sewing set
This is a flat set. Written quote along with industrial sewing machines set set sew the mouth, put that quote in a book linking the core. For the book block in the 100 the following books or pamphlets, no wire set available when sewing set.
(5) Perfect Binding
This is only after gaining popularity in the seventies as a book core set associative. As the name suggests, this provides an alternative to the joint line, but the quote in the book set out the mouth first broke open the burrs, and then coated with adhesive will be posted on the book I set out a book at each other bonding method of the core of a link. Tends to be used white latex adhesive or hot melt adhesive. Adhesive Binding books to read core smoothing are very good, is easy to realize mechanization, less than is sometimes quote the book stick together is not strong, easy off pages. Since the eighties, the book after it has become the main form of core-level set.
(6), saddle stitching
With only 12 copies of thin brochures printing and publications, can be used saddle stitching. The wire in the book quote of the folding joints from the outside through the crease, put that quote into a book link. Saddle stitching process is simple, high efficiency, low cost, easy to implement mechanization. However, this approach also has less stapler, one wire easy to rust; second book pages easy to fall off, so used for journal binding, is the main form of bound journals have been widely used.
