精装书的装订工艺主要有书芯加工、书壳制作和上书壳3个过程，下面
济南精装书制作厂家将对书芯加工事项进行详细的介绍：
The binding process of hardcover books mainly includes three processes: book block processing, book case manufacturing and book case loading. Jinan hardcover book manufacturer will introduce the book block processing in detail below:
书芯制作的前一部分和平装书装订工艺相同，包括：裁切、折页、配页、锁线与切书等。在完成上述工艺之后，就要进行精装书芯特有的加工过程。书芯为圆背有脊形式，可在平装书芯的基础上，经过压平、刷胶、干燥、裁切、扒圆、起脊、刷胶、粘纱布、再刷胶、粘堵头布、粘书脊纸、干燥等完成精装书芯的加工。书芯为方背无脊形式，就不需要扒圆。书芯为圆背无脊形式，就不需要起脊。
The former part of book block production is the same as the binding process of paperback, including: cutting, folding, matching, sewing and book cutting. After completing the above process, we need to carry out the special processing process of the hardcover book block. The book block is in the form of a round back with a ridge. On the basis of the paperback book block, the hardcover book block can be processed through flattening, gluing, drying, cutting, rounding, ridging, gluing, gluing, gluing gauze, re-brushing, gluing cloth, gluing spine paper, drying, etc. The book block is in the form of square back without ridge, so it does not need to be rounded. The book block is in the form of round back without ridge, so there is no need for ridge.
压平：压平是在专用的压书机上进行，使书芯结实、平服，提高书籍的装订质量。
Flattening: Flattening is carried out on a special book-pressing machine to make the book block strong and flat, and improve the binding quality of books.
刷胶：用手工或机械刷胶，使书芯达到基本定型，在下道工序加工时，书帖不发生相互移动。
Glue brushing: use manual or mechanical glue brushing to make the book block reach the basic shape. During the next process, the book post will not move each other.
裁切：对刷胶基本干燥的书芯，进行裁切，成为光本书芯。
Cutting: cut the book block that is basically dry with glue to become a light book block.
扒圆：由人工或机械，把书脊背脊部分，处理成圆弧形的工艺过程，叫做扒圆。扒圆以后，整本书的书贴能互相错开，便于翻阅，提高了书芯的牢固程度。
Rounding: The process of manually or mechanically processing the spine of the book into an arc shape is called rounding. After being rounded, the book stickers of the whole book can be staggered, which is easy to read and improves the firmness of the book block.
起脊：由人工或机械，把书芯用夹板夹紧加实，在书芯正反两面，接近书脊与环衬连线的边缘处，压出一条凹痕，使书脊略向外鼓起的工序，叫做起脊，这样可防止扒圆后的书芯回圆变形。
Ridge lifting: The process of manually or mechanically clamping and consolidating the book block with a splint, and pressing a dent on the front and back sides of the book block, close to the edge of the line between the spine and the ring liner, to make the spine bulge slightly outward, which is called ridge lifting, which can prevent the book block from being rounded back and deformed.
书脊加工：包括刷胶、粘书签带、贴纱布、贴堵头布，贴书脊纸。贴纱布能够增加书芯的连结强度和书芯与书壳的连结强度。堵头布，贴在书芯背脊的天头和地脚两端，使书帖之间紧紧相连，不仅增加了书籍装订的牢固性，又使书变得美观。书脊纸必须贴在书芯背脊中间，不能起皱、起泡。
Spine processing: including brushing glue, pasting bookmark tape, pasting gauze, pasting plug cloth, pasting spine paper. Sticking gauze can increase the connecting strength of the book block and the connecting strength of the book block and the book case. The cap cloth is pasted on the top and bottom of the back of the book block, making the book stickers closely connected, which not only increases the firmness of the book binding, but also makes the book beautiful. The spine paper must be pasted in the middle of the back of the book block, and cannot wrinkle or blister.
