What is a bolting cloth printing?

First, bolting cloth printing:

Bolting cloth printing includes the preparation of printing screens, printing screens (screens used in the printing process used to be made of fine silk, the process is called screen printing. Although silk screens are no longer used, printing The name screen printing is still often used in the process.) Made of fine mesh nylon, polyester or wire fabric that is tight on a wooden or metal frame. The polyester mesh screen fabric is coated with an opaque, non-porous film. At the pattern, the opaque film is removed, leaving a screen with fine mesh, which is the part where the pattern will be printed. Most commercial mesh fabrics are first coated with a photosensitive film, and then the film is removed by photographic method to reveal the pattern. A screen is placed on the fabric to be printed for printing. The printing paste is poured into a printed frame and forced through the mesh of the screen by a doctor blade (a tool similar to a wiper on a car windshield). Each color in the print pattern requires a screen alone to print different colors. Example 3 sets of color printing requires 3 frames, and the 3 colors are printed on the fabric separately. In addition, the pattern of each color in the pattern must be accurately positioned on the screen so that the position of the pattern after printing is accurate, avoiding the phenomenon that the green stem of a rose is printed in the middle of the red petals. Print-to-flower refers to the industrial term for all pattern colors printed on fabrics.

First, manual screen printing:

The printing is commercialized on a long platen (the platen is up to 60 yards long). The printed cloth roll is smoothly spread on the platen, and the surface of the platen is pre-coated with a small amount of viscous material. The printer then continuously moves the frame by hand along the entire platen, printing one frame at a time until the fabric is completely printed. Each frame corresponds to a printed color. This method is produced at a speed of 50-90 yards per hour. Commercial hand screen printing is also widely used to print sanctioned cut pieces. In the film printing process, the garment process and the printing process are arranged together. Customized or unique patterns are printed on the pieces before the pieces are sewn together. Because the manual screen printing can make large frame for the large flower back pattern, the printing method can also print fabrics such as beach towel, novel printed apron, curtain and shower curtain, and manual screen printing is also used for printing. Limited, highly fashionable women's clothing and products that are printed in small quantities for market exploration.

Second, automatic screen printing:

Automatic screen printing (or flat screen printing) is faster than the manual screen, except that the process is automated. The printed fabric is conveyed to the screen through a wide rubber band and is not placed on the bench (like a hand screen print). As with manual screen printing, automatic screen printing is also a batch rather than a continuous process. In this process, the fabric is moved under the screen, then stopped, and the screen scraper is used for scratching (automatic scraping). After the printing, the fabric continues to move under the next frame, and the production speed is about 500 yards per hour. . Automatic screen printing can only be used for whole rolls of fabric, and cut pieces are generally not printed in this way. As a commercial production process, the output of automatic screen printing (referred to as flat screen printing) is declining due to the preference for more efficient rotary screen printing.
