The main difference between hardcover and paperback is the making of the hardcover cover.

Speaking of hardcover book printing, many people think that compared with hardcover books and paperback books, there does not seem to be much demand, and the production cost should not be too different. In fact, from the hardcover printing process, the paperback book does not have much difference, but the key to making a hardcover book is producing the hardcover book cover. The cover and back cover of hardcover books are generally made of silk fabrics, varnished cloth, artificial leather, leather or paper, which are pasted on the surface of cardboard to form a bookcase.

The hardcover book is completed in three steps according to the processing method of the cover.

According to the processing method of the cover, the hardcover book is divided into two bookcases with spline groove and without spine groove. The textbook back of the book block can be processed into the hardback, cavity back and softback, etc., with a beautiful appearance, solid and durable.

The process is: making the book block → making the bookcase → adding the bookcase.

1. The production process of the hardcover book block

The first part of the hardcover book block is the same as the binding process of the paperback book, including cutting, folding, collating, threading and cutting, etc. The book block is in the form of a round back with a spine. The paperback book block can be flattened, brushed, dried, cut, rounded, ridged, brushed, glued, gauze, re-brushed, and plugged. , Gluing the spine paper, drying, etc., to complete the processing of the hardcover book block. The book block is in the form of a square back without a spine and does not need to be rounded. The book block is around the back without a range, and no spine is required.

2. The making of a hardcover bookcase

The cover is the cover of the hardcover book. The material of the bookcase should have a certain degree of strength and wear resistance and have a decorative effect. A bookcase made by connecting the front cover, back cover and back with a whole piece of fabric is called a monolithic bookcase.

The cover and back cover are made of the same fabric, while the back is made of another piece of cloth, which is called the ingredient book cover.

When making the bookcase, cut the cover material according to the specified size, brush the glue, and then compact and position the cardboard of the front and back seals, wrap the edges and corners, and flatten to complete the bookcase. Due to the low efficiency of manual operation, the bookcase is now made by machinery. KSprinting recently introduced a fully automatic hardcover book sealing machine, which provides a strong guarantee for improving hardcover book production and fast shipping quality.

3. Add the book cover

It is the process of connecting the bookcase and the book block, and the method of adding the bookcase is:
First, apply glue on one side of the book block, place it on the bookcase according to a specific position to make the book block and the bookcase stick firmly, and then stick the other side of the book block smoothly method. On the bookcase, the entire book block is firmly connected to the bookcase. Then use a crimping machine to press a groove on the front and back edges of the book, pressurize and dry, make the book printing more smooth and finalized, and then be delivered to the customer from the printing factory.
