Hardcover is generally used for books with a large number of pages, which need to be read and saved repeatedly and have high quality requirements. The cover and back cover of a hardcover book are usually made of silk, lacquer cloth, artificial leather, leather or paper and pasted on the surface of cardboard to make a book case. According to the processing method of the cover, there are spine and non spine book cases. The back of the book block can be processed into hard back, cavity back and soft back. Hardcover books are strong and durable with high quality requirements.

精裝書(shū)的裝訂工藝主要有書(shū)芯加工、書(shū)殼制作和上書(shū)殼3個(gè)過(guò)程，下面將對(duì)各個(gè)部分進(jìn)行詳細(xì)的介紹：

The binding process of hardcover books mainly includes three processes: book block processing, case making and case loading. Each part will be introduced in detail below:

（一）書(shū)芯加工

（1） Book block processing

書(shū)芯制作的前一部分和平裝書(shū)裝訂工藝相同，包括：裁切、折頁(yè)、配頁(yè)、鎖線與切書(shū)等。在完成上述工藝之后，就要進(jìn)行精裝書(shū)芯特有的加工過(guò)程。書(shū)芯為圓背有脊形式，可在平裝書(shū)芯的基礎(chǔ)上，經(jīng)過(guò)壓平、刷膠、干燥、裁切、扒圓、起脊、刷膠、粘紗布、再刷膠、粘堵頭布、粘書(shū)脊紙、干燥等完成精裝書(shū)芯的加工。書(shū)芯為方背無(wú)脊形式，就不需要扒圓。書(shū)芯為圓背無(wú)脊形式，就不需要起脊。

The binding process of the first part of the book block is the same as that of the paperback book, including cutting, folding, page matching, sewing and book cutting. After completing the above process, we need to carry out the unique processing process of hardcover book block. The book block is in the form of round back with ridge. On the basis of paperback book block, the hardcover book block can be processed through flattening, glue brushing, drying, cutting, rounding, ridging, glue brushing, gauze sticking, re glue brushing, plug cloth sticking, spine paper sticking, drying, etc. The book block is in the form of square back without ridge, so there is no need to pick a circle. The book block is in the form of round back without ridge, so there is no need for ridge.

壓平：壓平是在專(zhuān)用的壓書(shū)機(jī)上進(jìn)行，使書(shū)芯結(jié)實(shí)、平服，提高書(shū)籍的裝訂質(zhì)量。

Flattening: flattening is carried out on a special book press to make the book block firm and flat, and improve the binding quality of books.

刷膠：用手工或機(jī)械刷膠，使書(shū)芯達(dá)到基本定型，在下道工序加工時(shí)，書(shū)帖不發(fā)生相互移動(dòng)。

Glue brushing: use manual or mechanical glue brushing to make the book block reach the basic shape. During the next process, the book posts will not move each other.

裁切：對(duì)刷膠基本干燥的書(shū)芯，進(jìn)行裁切，成為光本書(shū)芯。

Cutting: the book block with basically dry glue brush is cut to become a light book block.

扒圓：由人工或機(jī)械，把書(shū)脊背脊部分，處理成圓弧形的工藝過(guò)程，叫做扒圓。扒圓以后，整本書(shū)的書(shū)貼能互相錯(cuò)開(kāi)，便于翻閱，提高了書(shū)芯的牢固程度。

Round raking: the process of manually or mechanically processing the spine into a circular arc, which is called round raking. After rounding, the book stickers of the whole book can be staggered with each other, which is easy to read and improves the firmness of the book block.

起脊：由人工或機(jī)械，把書(shū)芯用夾板夾緊加實(shí)，在書(shū)芯正反兩面，接近書(shū)脊與環(huán)襯連線的邊緣處，壓出一條凹痕，使書(shū)脊略向外鼓起的工序，叫做起脊，這樣可防止扒圓后的書(shū)芯回圓變形。

Ridging: manually or mechanically clamp the book block with a splint, and press out a dent on the front and back sides of the book block, close to the edge of the connecting line between the book ridge and the ring lining, so as to make the book ridge bulge slightly outward, which is called ridging, so as to prevent the back round deformation of the book block after rounding.

書(shū)脊加工：包括刷膠、粘書(shū)簽帶、貼紗布、貼堵頭布，貼書(shū)脊紙。貼紗布能夠增加書(shū)芯的連結(jié)強(qiáng)度和書(shū)芯與書(shū)殼的連結(jié)強(qiáng)度。堵頭布，貼在書(shū)芯背脊的天頭和地腳兩端，使書(shū)帖之間緊緊相連，不僅增加了書(shū)籍裝訂的牢固性，又使書(shū)變得美觀。書(shū)脊紙一定要貼在書(shū)芯背脊中間，不能起皺、起泡。

Spine processing: including brushing glue, pasting bookmark tape, pasting gauze, pasting plug cloth and pasting spine paper. Sticking gauze can increase the connection strength of the book block and the connection strength between the book block and the book case. The capping cloth is pasted on both ends of the crown and foot of the spine of the book block, so that the books are closely connected, which not only increases the firmness of book binding, but also makes the book beautiful. The spine paper must be pasted in the middle of the back of the book block without wrinkling or blistering.

（二）書(shū)殼的制作

（2） Making of book case

書(shū)殼是精裝書(shū)的封面。書(shū)殼的材料應(yīng)有一定的強(qiáng)度和耐磨性，并具有裝飾的作用。用一整塊面料，將封面、封底和背脊連在一起制成的書(shū)殼，叫做整料書(shū)殼。封面、封底用同一面料，而背脊用另一塊面料制成的書(shū)殼，叫做配料書(shū)殼。

The book case is the cover of a hardcover book. The material of the book case should have certain strength and wear resistance, and have the function of decoration. A book case made of a whole piece of fabric connecting the cover, back cover and back is called a whole book case. The cover and back cover are made of the same fabric, while the spine is made of another fabric, which is called the batched book case.

作書(shū)殼時(shí)，先按規(guī)定尺寸裁切封面材料并刷膠，然后再將前封、后封的紙板壓實(shí)、定位（稱(chēng)為擺殼），包好邊緣和四角，進(jìn)行壓平即完成書(shū)殼的制作。由于手工操作效率低，現(xiàn)改用機(jī)械制書(shū)殼。制作好的書(shū)殼，在前后封以及書(shū)背上，壓印書(shū)名和圖案等。為了適應(yīng)書(shū)背的圓弧形狀，書(shū)殼整飾完以后，還需進(jìn)行扒圓。

When making a book case, first cut the cover material according to the specified size and apply glue, then compact and position the front and rear sealing paperboards (called swing case), wrap the edges and four corners, and press flat to complete the production of the book case. Due to the low efficiency of manual operation, we now use mechanical book case. The title and pattern of the book are stamped on the front and back seals and the back of the book. In order to adapt to the arc shape of the back of the book, the book case needs to be rounded after finishing.

（三）上書(shū)殼

（3） Upper book case

把書(shū)殼和書(shū)芯連在一起的工藝過(guò)程，叫做上書(shū)殼，也叫套殼。

The technological process of connecting book case and book block together is called upper book case, also known as sleeve case.

上書(shū)殼的方法是：先在書(shū)芯的一面襯頁(yè)上，涂上膠水，按一定位置放在書(shū)殼上，使書(shū)芯與書(shū)殼一面先粘牢固，再按此方法把書(shū)芯的另一面襯頁(yè)也平整地粘在書(shū)殼上，整個(gè)書(shū)芯與書(shū)殼就牢固地連結(jié)在一起了。用壓線起脊機(jī)，在書(shū)的前后邊緣各壓出一道凹槽，加壓、烘干，使書(shū)籍更加平整、定型。如果有護(hù)封，則包上護(hù)封即可出廠。

The method of putting on the book case is: first, apply glue on the lining page on one side of the book block, and put it on the book case according to a certain position, so that one side of the book block and the book case can be firmly adhered, and then the lining page on the other side of the book block can be smoothly adhered to the book case according to this method, and the whole book block and the book case can be firmly connected. With the line pressing and ridging machine, press out a groove on the front and rear edges of the book, pressurize and dry, so as to make the book more flat and shaped. If there is a protective seal, it can leave the factory with the protective seal on the package.
