The film is a transparent plastic film adhered to the surface of the book cover by hot pressing to make it resistant to friction, moisture, light, water and dirt, and to increase its luster. There are two types of films, high-gloss type and matt type. The high-gloss type film makes the surface of the book dazzling and magnificent; the matt type film makes the book simple and elegant. The dumb film makes the print color darker and softer, while the bright film makes the print color more brilliant, but it is prone to chaotic reflections. The cost of the dumb film is higher than that of the bright film. Simply put, sub-film prints can be viewed from all angles, while bright film prints can only be seen from a fixed angle. However, the plastic film currently used for the film is a non-degradable material, which is not good for environmental protection. Now 90% of the books are using this process, generally local UV coating is also done on the book cover with the film.
3. Bump embossing
This is a process of "printing" without ink. Concave and convex embossing is also called embossing, embossing, and embossing. It uses matching concave and convex steel molds or copper molds to extrude the entire figure or the outer contour of the printed pattern in a concave and convex three-dimensional shape. In book binding, concave-convex embossing is mainly used to print letter sleeves, cover text and patterns or wireframes to improve the three-dimensional effect of the printed matter. It can also be printed with ink or partial UV glazing after embossing to make graphics and texts. More prominent. This process is also widely used on the cover or cover of hardcover or paperback books. With hand-carving, three or four levels of relief effects can also be made.
4. Color foil hot stamping
Color foil hot stamping is a hardcover book cover made of wood, leather, fabric, paper or plastic. The book title is printed with gold, silver, red or other colors of electrochemical aluminum foil or powder foil (matt) by heating Or patterns, wireframes, etc. The hardcover book cover looks noble and gorgeous after being hot stamped with colored foil, which can enhance the sparkle of the printed matter. This method is widely used in cover finishing. In the past, hot gold and silver were often used on the cover and back of hardcover books, but now there are more and more hot gold and silver on the cover and back of paperback books. Some paperback books are still hot stamped and silver on the ring lining and title page, because the gold and silver printed on the colored paper of the ring title can produce a unique effect.
5. Die cutting, indentation
Die-cutting is the process of using steel blades to form a die-cutting plate, and rolling and cutting printed matter or paper into a certain shape on a die-cutting machine. It can roll-cut the printed matter into arcs or other complex shapes, or punch the printed matter. Or hollow and other processing.
Indentation is also called indentation line or indentation line. Steel wire is used to emboss to make marks on printed matter or leave grooves for bending. Generally, the cover of a thicker book must be indented on the left side of the cover.
6. Printing (embossing)
Pressing different textures on the surface of paper or cardboard can change the texture of ordinary coated paper or cardboard to make it look like leather, cloth, hemp, woven, felt, bark, wood grain, and pear bark. , Orange peel, etc., not only can make it have the elegant texture of clouds and leaves, but also make it have the solemn texture like oracle bone inscriptions and earthenware.

Plastic dropping is to evenly drop transparent soft or hard crystal glue onto the surface of the object, so that the surface of the object obtains a crystal-like and three-dimensional effect. It can be dripped on the surface of paper, polyester, PVC, metal and other materials. The dripped surface is also resistant to water, moisture, and UV light.
8. Refraction indentation
Refraction indentation is the use of dense embossing process on the surface of mirror substrates that have been hot stamped with anodized aluminum foil or sprayed aluminum paper to produce fine uneven lines such as straight lines or arcs in different directions. It does not use ink, and can make full use of the surface state of the paper. According to the principle of light diffusion, it reflects the changes of light from multiple angles, and can produce hierarchical three-dimensional images on the screen, so the refractive print has a unique and charming effect. The different reflections of light by the uneven lines on the surface make the image on the surface of the book shining, novel and unique. With the change of the light receiving angle, the image text is looming, full of dynamic and three-dimensional, lifelike, and has an anti-counterfeiting effect. The paper for refraction processing is generally aluminized paper, with gold and silver on the surface, and matte paper. The available basis weight is 80-250g/m2.
9. Surface matte
