What are the printing process in book printing?
When it comes to printed matter, many people are no strangers to it, and we cannot do without it in our daily work and life. But when it comes to the craftsmanship of printed matter, many people may not be clear about it. Today, the China printing company simply sorted out some of the more commonly used printing processes for everyone to see:
1. Hot stamping
Hot stamping refers to the processing of transferring hot stamping materials or hot stamping patterns on paper (printed matter) by hot stamping. Generally, there are hot stamping, hot silver, etc., which are often used for red envelopes, book covers or high-end business cards.
Punching is easier to understand, that is, to punch a hole in the printed paper, usually a round hole, which is often used for hanging tags, handbags, etc. for stringing.
Over-film, also called glue, is to attach a layer of film to the paper to make the printed matter moisture-proof, waterproof, and not easy to be torn. There are two types of film: light film and dumb film. The best way to distinguish is that the light film reflects light under light, while the dumb film does not.
Folding is a necessary process in the printing industry. The large paper printed by the printing press must be folded to form promotional folds, books, newspapers, etc. There are also many types of folding methods. According to the number of folds, they are divided into two folds, three folds, and four folds; according to the folding method, they are divided into heart folds and organ folds.
5. Pressure line
The pressing process is special, it is aimed at thicker paper. When the thickness exceeds a certain value, if you need to fold, generally you must first press the line to be folded with the machine before folding.
6. Punching a pinhole
Pinhole refers to punching a row of pinhole lines on the paper, and its main purpose is to facilitate the tearing of the paper. Often used for tickets, coupons, etc., it is convenient to tear off the sub-coupons when using them.
Coding refers to printing a different and continuous series of numbers on printed matter to distinguish different printed matter. Generally used for lottery tickets, duplicate coupons, etc.
8. Beer shaped
Bie (bie) shaped refers to cutting out irregular shapes with a knife die, which is often used for some shaped business cards and so on.
UV refers to applying a layer of oil on a specific area or pattern of the paper, which can increase the brightness of the product and enhance the visual effect.
10. hit the convex
When embossing, a set of concave and convex stencils corresponding to the yin and yang of the graphics and text are used, and the substrate is placed in between, and the embossed concave-convex graphics and text can be pressed out by applying greater pressure, which can greatly increase the layering of the printed pattern.
Embossing is also a process of using a concave-convex mold to plastically deform the printed matter under a certain pressure, thereby performing artistic processing on the surface of the printed matter. However, the surface of the paper presents textures of different depths, increasing the three-dimensional effect.
12. Horse riding studs
Saddle stitch is a binding method for books, magazines and picture albums. It is called saddle stitch because of the action such as stepping on a horse's back. Others include wireless plastic binding and threaded plastic binding. Generally, saddle stitches are only suitable for books and periodicals with a small number of P. If the number of P is large, glue binding is required.
The above are some of the common processes in printing by printers in China. General business cards and single-sheet printing will only involve these processes. There are other special processes for other different categories such as packaging boxes and stickers.
