Hardcover refers to an exquisite method of making books. Hardcover books are mainly made after various modeling processing on the back and corner of the book cover and block. There are many kinds of processing methods and forms, such as round back (ridged or not ridged), square back, square corner and fillet; Cover processing is divided into the whole face, joint face, square corner, hot foil, hot embossing patterns and so on. Next, I will explain the production method and technology of hardcover book.

手感

feel

持书有实重感，书槽明显有凹陷感，翻动前后皮壳面180°无吱吱声响，皮壳面书槽与衬纸出现假粘现象 。

There is a real heavy feeling when holding the book, and there is an obvious concave feeling in the book slot. The leather surface is 180 before and after turning ° There is no squeaking sound, and there is false adhesion between the book slot on the leather case and the backing paper.

除上述装订相关工序质量外，打孔两头须居中、孔口平齐、无毛边，收口位为1mm，铁线不超过书芯。这样，给人以不乏现代美感中的纯朴、而更兼有现代工艺中的精致，总是把这些细节处理的很好，让精装书看起来更高 档。

In addition to the quality of the binding process mentioned above, the two ends of the hole should be in the middle, the hole should be flush, without burr, the closing position should be 1 mm, and the iron wire should not exceed the book block. In this way, it gives people not only the simplicity of modern aesthetic feeling, but also the delicacy of modern craft. They always deal with these details well, making the hardcover book look more high-grade.

总之，一本好的精装书并非偶然所得，制作过程中需各工序质量的严格把关，直到后面工序产品质量完全合格。

In a word, a good hardcover book is not obtained by accident. In the production process, we need to strictly control the quality of each process until the product quality of the later process is completely qualified.

流程共分三条线，即书芯、书封和套合。

The process is divided into three lines, namely book block, book cover and sleeve.

书芯加工流程:半成品印张开始→撞页→开料→粘、套页→粘环衬→配页→锁线→半成品检查→压平→堆积压平→切书→捆书→涂黏合剂~→干燥分本→切书→

Book block processing process: semi finished sheet printing → page bumping → cutting → gluing and page setting → gluing ring lining → page matching → sewing → semi finished product inspection → flattening → stacking and flattening → book cutting → book binding → applying adhesive ~ → drying and Book splitting → book cutting →

涂黏合剂→扒圆→起脊→涂黏合剂→ 潮湿→粘书签丝带→粘堵头布→涂黏合剂→粘书背布→粘书背纸→涂黏合剂→粘筒子纸。

Apply adhesive → pick circle → ridge → apply adhesive → wet → stick bookmark ribbon → stick plug cloth → apply adhesive → stick book back cloth → stick book back paper → apply adhesive → stick bobbin paper.

书封加工流程:计算书封壳各料尺寸→开料→涂黏合剂→组壳→包壳塞角→压平→自然干燥→烫印。

Book seal processing flow: calculate the size of each material of the book seal shell → cutting → coating adhesive → shell assembly → shell plug angle → flattening → natural drying → hot stamping.

套合加工流程:涂中缝黏合剂→套壳→压槽→扫衬→压平定型→自然干燥→成品检查→包护封→包装贴标识。

The process flow of nesting: apply the middle seam adhesive → sleeve shell → groove pressing → lining sweeping → flattening and shaping → natural drying → finished product inspection → package protection → package labeling.
