Loose and loose-leaf binding
Loose page refers to a single-page printed product that is formed by four-sided cutting according to the final size after the printing sheet is printed, folded, and collated. The loose-leaf binding is punched to form loose-leaf pages. Loose-leaf binding is to complete the binding of loose-leaf pages and other inserts.

Loose-leaf binding process
1. Iron ring binder
Iron ring binder is an exquisite appearance, easy to use, and versatile data sorting tool. Compared with the traditional wire binding and glue binding, it can better adapt to the binding of multiple types and numbers of text pages and inserts. Common binders commonly used in offices are mainly used for collecting loose-leaf materials, etc. If you need to accommodate operating manuals, video materials, magnetic tapes, product catalogs, physical samples, etc., you need to be tailored by a professional printing company and designed according to actual needs. For details such as pockets, the ring binder is a good choice. As shown in Figure 1. Using the ring binder binding process, the following selection is required.

(1) Choose the appropriate shell style
There are three main types of shells for iron ring binders: polyethylene shells, vinyl shells and edging shells. Polyethylene sheet is semi-rigid, with a thickness of 0.4 to 2.8mm, and has strong and durable characteristics. For those prints that need to be frequently used in workshops or outdoor operations in poor environments, polyethylene materials are ideal. Program. The vinyl shell (shown in Figure 2) is made of vinyl plastic film wrapped around the cardboard and then heat-sealed along the outer edges of the surroundings. It has the characteristics of flexible structure and good versatility. A variety of pockets can also be attached to the inside of the shell , CD sets, etc. The edging shell (as shown in Figure 3) is to first stick the selected cover material on the cardboard, and paste the lining on the inside of the shell, and finally install the iron ring clip at the back of the book. Due to the characteristics of bright colors, rich layers, and vivid images, offset printed products are often used as shell materials for film-coated offset printing products, and sometimes special materials such as cover cloth or artificial leather are also used.

The finishing process of the shell of the binder includes offset printing, screen printing, hot stamping, embossing, and die-cutting, etc. Generally, related content such as company logos or other important graphic information is also printed on the cover. Generally speaking, the structure, materials and decoration scheme of the binder casing need to be determined according to the number, content and cost requirements of the binder binding.
(2) Choose the shape of the iron ring
The shape of the iron ring directly affects the use effect of the loose-leaf product. There are three types of ring, straight D ring and oblique D ring, as shown in Figure 4. Among them, the diameter of the ring and the straight D ring is 1/2 to 3 inches, and the diameter of the oblique D ring is 3/4 to 4 inches. The ring and straight D ring are suitable for most loose-leaf products. They are easy to use and durable, as shown in Figure 5. The oblique D ring is suitable for loose-leaf binding with index labels. In contrast, the oblique D-ring binder has index labels, which makes it easier to browse and query, and the loose-leaf is not easy to be damaged. The loose-leaf capacity is large, and it is more convenient to add or delete. The ring binder generally adopts a riveting method to fix the iron ring frame to the back of the casing. Therefore, the back of this type of binder will have rivets exposed. For the sake of beauty, circular dark rivets can be used; the riveting positions of the straight D ring and the oblique D ring are set on the back cover, and the rivets penetrate the back cover, as shown in FIG. 6.

(3) Choose the iron ring frame that matches the finished product
The capacity of the iron ring for loose pages is related to the diameter, and the diameter of the iron ring should match the number and thickness of the bound pages. If the diameter is too large or too small, the page will be damaged. In addition, try to use high-quality iron ring frame, if the material is not good, its opening and closing performance will be greatly reduced, easy to cause poor reading, or even tear the inner page.
(4) Select hole
There are two types of loose-leaf binding holes: oval holes and round holes. If the number of inner pages is large, oval holes are recommended.
