1. UV glazing
UV (Ultraviolet) also called UV curing glazing glazing process. UV glazing oil is in the 1980 s the rise of new material. Glazing technology can enhance the appearance of the print, the color is more bright-coloured and bright, and it also can improve the performance of printed matter, enhance the protection performance of the print. UV glazing whole wide glazing and partial glazing. The former is referred to as "UV oil" or "oil", the latter is referred to as "local UV". UV glazing type with high gloss and matte type two kinds. UV glazing quality is quite high, local UV glazing, especially by comparison with high gloss and matte screen can produce wonderful artistic effect. At the same time, the ultraviolet radiation curing, does not produce waste, no pollution to the environment.
Local UV glazing, combining with other process also to make ice, foaming, wrinkles, grinding, such as refraction, pearl effect. Since the local UV glazing appear in books after finishing a couple of years ago, in 2003, and 2004 presented a use, are widely applied to press the cover of the book binding, especially children, economics, literature, management, by category.
2. The effect of
Coated with transparent plastic film by hot pressing is attached to the surface of a sealed book, the friction resistance, resistance to moisture, light, waterproof and antifouling functions ", and increase its luster. Has two kinds of high gloss and matte film, high gloss sparkling type thin film surface of books and gorgeous; Matt is books of primitive simplicity, and elegance. But the effect of the used plastic film is non-biodegradable material, adverse to the environment. Now 90% of all books in the use of the process, the general and local UV glazing, are also on the cover of the books in the membrane. Some printing enterprise in the use of environmental protection membrane, some local UV glazing in test is not coated. Foreign books, generally not coated, domestic also has many publishers began to abandon laminating and low use cost and environmental protection way of UV glazing cover trims.
3. The concave-convex embossing
This is not ink for "printing" process. Concave-convex embossing and pressure bump, convex, convex, concave and convex model is the use of mutual matching steel or copper, delivery is concave and convex three-dimensional shape of the graphic or plating design Outlines. In book binding, concave-convex embossing are mainly used for printing HanTao, cover text and pattern or wire frame, in order to improve the print of the stereo feeling, also can be in after the concave-convex embossing printing ink or local UV glazing, make the graphic more outstanding. This technology is also widely used in hardcover or paperback books seal shell and cover. With manual sculpture, but also can make three or four levels of emboss effect.
4. Color foil hot stamping
Color foil hot stamping is in wood, leather, fabric, paper or plastic on the cover of the book and other materials, in gold, silver, red or other colors of electrochemical aluminium foil or powder foil (matte) printed on the title or by heating pattern, wireframes, etc. Book covers after color foil stamping appears high and luxuriant, enhanced the light flashes of the print. Trims used widely cover this way. Used in hardcover book cover and book bronzing, hot silver, and now and book in paperback cover bronzing, hot silver, also more and more. Some still in paperback book HuanChen appears on the title page, bronzing, hot silver, because silver print on the ring leaf color paper, can produce lasting appeal unique effect.
5. Die cutting and creasing
Die cutting is to use steel knife tablets in die cutting, print or paper mill on the die-cutting machine cut into certain shape, it can be print or other complex shape rolling cut into arc, can also be carried out on the print punching processing or hollow out, etc.
Indentation also called indentation line or wire, using steel wire, through the pressure seal, pressure on the print out, or leaving the groove for bending. Generally thicker cover books, in the fold on the left side of the cover in indentation processing.
6. Plating (embossing)
In paper or cardboard surface suppression of different texture of the grain, can change the normal texture on the surface of the coated paper or cardboard to make it like leather, cloth, hemp products, weaving, carpet, bark, wood grain, pear peel, orange peel, etc., can make it with the clouds, leaves, elegant lines, also can make its have the dignified like oracle, earthenware grain. Now used for the design of lines on the surface of the books can follow one's inclinationsly, and can be on a page printed on several different lines at the same time.
7. Plastic
Plastic is a transparent flexible or rigid crystal glue evenly onto the surface, make the surface have a glittering and translucent crystal, three-dimensional effect. Can be plastic in the material such as paper, polyester, PVC, metal surface, plastic surface also has a water resistant, resistant to moisture, UV light resistance and other properties.
The refractive indentation 8.
Refraction indentation is conducted has a electrochemical aluminum foil hot stamping or mirror substrates such as aluminum paper surface with the aid of lp pressure convex process from different directions are arranged in a straight line or arc slightly concave and convex lines. Can make full use of it instead of ink, paper surface state, according to the principle of the diffuse light, multi-side light changes, can make the picture have layers of depth image, so the refractive printing has a unique charming effect. Its on the surface of the concave and convex lines on the surface of the light reflection to make different books image shines, novel and chic, with the change of the Angle by light, the image text is like concealed, extremely rich move feeling and stereo feeling, lifelike, and have anti-counterfeit effect. Refraction processing generally for aluminized paper, paper surface of gold, silver, etc, and have the matte paper, of quantitative is 80 ~ 250 g/m2.
9. The surface grinding
Use of external force, by breaking the print surface deformation with 3 d effect and uniform sand of concave and convex point. The process often applied together with hot stamping. (Gold Printing Group)
