The processing of soft hardcover book printing is the same as that of hard hardcover book printing, which can be produced by the hardcover linkage line with high efficiency. For books with special specifications and materials, a small number of printed sheets and hardcover requirements, they can also be bound manually. In the nesting process, in addition to some plastic looper book cases, most soft hardcover books still need to go through the processing processes of shell, lining and pressing. Due to the particularity of plastic and paper plastic cover, when selecting adhesive, it can not be equal to general paper adhesive. In order to ensure the bonding fastness between paper and plastic, the mixed adhesive composed of paste and 504 glue is generally used.
