This is a commonly used printing method and the price is moderate, so many manufacturers use this method. This printing method uses the LOGO file to make a film, and then the film can be used to dry out the screen. After drying the LOGO, the screen can be made into a printing plate before printing. It is very important to print the plate. If the plate is not dried well, the printed effect will not be good. There are two types of silk screen printing: manual screen printing and machine screen printing. It is an older printing method.

2. Offset printing

It is the abbreviation of machine offset printing. By making a soft offset plate and pasting it on the printing drum of the printing machine, one or both of them can be printed each time it rotates. Logo for multiple bags. This printing method is mainly fast and has good effects, which is inferior to silk screen printing. However, because of its lower price, more and more manufacturers are adopting this printing method.

3. Peritoneum

The finished product processed in this way is usually called a composite non-woven bag. First, the traditional gravure printing process is used to print graphics and text on the film, and then the laminating process is used to laminate the printed film onto the non-woven fabric. Generally, patterned non-woven bags with higher requirements or more colors will use this process. It is characterized by exquisite printing, machine production and fast production speed. The finished product has excellent waterproof performance, and the durability of the finished product is also better than non-woven bags produced by other processes. Peritoneum: There are two types of peritoneum: bright film and matte film, but their cost is high.

4. Thermal transfer printing

It is a special type of printing! This printing method needs to be completed through an intermediate medium, that is, the graphics and text are first printed on the thermal transfer film or thermal transfer paper, and then the pattern is transferred to the non-woven fabric through heating by the transfer equipment. The commonly used medium in textile printing is thermal transfer film. This printing is exquisite, has rich layers, and is comparable to photos, but the printing cost is higher.

5. Copperplate printing

According to data, copperplate printing first appeared in the Song Dynasty and was used for paper printing. This process was also used on non-woven bags later. The production process of copper plates is relatively complicated and slow. Currently, it takes 6-10 days to make a copper plate, and the printing fee is relatively high. But it has long service life, good printing effect and fast speed, so it is widely used.

6. Dye sublimation

It is a technology that uses the action of water to transfer flat printed graphics and text to the surface of objects of different materials. Water transfer printing is divided into water mark transfer printing There are two types: water coating, transfer printing and curved coating. You can print the pattern you want on a variety of objects just by passing water. This is the most widely used printing nowadays. As long as the special adhesive film is placed on the water surface and then sprayed with a reagent, objects of various shapes can be given a new coat, and the effect and durability are just like baking paint, which can be printed almost everywhere. However, the cost of this process is relatively high.

7. Watermarking

It is named because it uses water-based elastic glue as the printing medium. It is common in textile printing and is also called printing. When printing, mix the color paste and water-based elastic glue. No chemical solvents are needed when washing the printing plate, it can be washed directly with water. It is characterized by good tinting power, strong covering and fastness, washability and basically no odor.
