1. UV coating
UV (Ultraviolet) glazing process is also called ultraviolet curing glazing. The glazing technology can enhance the appearance effect of the printed matter, the colors are more vivid and bright, and it can also improve the use performance of the printed matter and enhance the protective performance of the printed matter. UV coating is divided into full-frame surface coating and partial coating. The former is called “over-UV oil” or “over-oil” by the industry, and the latter is called “partial UV”. Since partial UV coating appeared in book finishing a few years ago, it has a climax of use in 2003 and 2004. It has been widely used by publishing houses for book cover binding, especially for children, finance, literature, and management. Books of class and graphic class.
2. Laminating：Matt and glossy
The covering film is made of transparent and plastic packaging film that can be adhered to the surface of the book cover by hot pressing, so that it has the functions of friction resistance, moisture resistance, light resistance, water resistance and antifouling, and its luster is continuously increased. There are two different types of films, high-gloss type and matt type. High-gloss type film makes the surface of book materials not dazzling and magnificent; matt film is important for book design to be simple and elegant. The dumb film makes the color of printed advertisements darker and softer, while the bright film makes the print color more brilliant, but it is prone to chaotic reflections. The cost management of the dumb film is higher than that of the bright film. Simply put, sub-film printed matter can be seen from the perspective of all companies, while the quality of bright film printing can only be seen from the perspective of fixed assets. However, the plastic composite film, currently use is an inevitable degradation material, which is not good for environmental protection. At present, 90% of the book information is researching the technology of using the network. Generally, partial UV coating is used, and it is also done on the book reading cover with the film.
3. Bump embossing
This is the process of “printing” without ink. Embossing, also known as embossing, embossing, embossing, and embossing, uses a matching concave-convex steel mold or copper mold to emboss into a concave-convex three-dimensional overall pattern or outline of a printed pattern. In book binding, intaglio relief is mainly used for printing envelopes, cover text and patterns or wireframes to improve the three-dimensional effect of the printed product. Ink or partial uv glazing can also be applied to the intaglio to make the graphics more prominent. This process is also widely used on the shell or cover of hardcover books or hardcover books. By hand-carving, three or four levels of relief effects can also be made.
4. Color foil hot stamping
Color foil hot stamping is made on the book cover made of wood, leather, fabric, paper or plastic, and printed with gold, silver, red or other different colors of electrochemical aluminum foil or powder foil (matt) through controlled heating A book title or pattern, wireframe, etc. As the cover, the book is more noble and gorgeous after being hot stamped with colored foil, which can enhance the sparkle of printed matter. This teaching method is widely used by cover decoration models. In the past, used to bronz and hot silver on the cover and back of hardcover books, but now the cover and back of paperback books are more and more hot. Some companies on paperbacks can still bronzing and silvering on the ring lining and title page, because Chinese gold and silver are printed on the color of the ring or paper, which has a unique effect of creating cultural charm.
5. Die cutting, indentation
Die-cutting is a process that uses steel blades to form a die-cutting plate. On a die-cutting machine, the printed matter or paper is rolled into a process that requires a certain shape. These printing qualities are processed for information processing such as design punching or hollowing. Indentation technology is also called indentation line or indentation line. It uses steel wire to increase the embossing to make marks on printed matter or leave grooves for bending. Generally, thicker book covers are used, and students are required to measure indentation on the left side of the cover.
6. Printing (embossing)
The utility model can change the surface texture of ordinary coated paper or cardboard by pressing different textures on the surface of paper or cardboard, such as leather, cloth, linen, weaving, felt, bark, wood grain, pear peel, orange peel, etc. Not only can it have flowing moire and leaf patterns, but it can also have dignified textures such as oracle bone inscriptions and pottery. Now the lines used on the surface of the book can be designed at will, and several different lines can be printed on one page at the same time.
