Screen printing includes the preparation of printing screens, and printing screens (screens used in the printing process were once made of fine silk, and the process is called screen printing. Although silk screens are no longer used, printing The name “screen printing†is also often used in the process.) Made of fine mesh nylon, polyester or wire fabrics that are tight on wooden or metal frames. The screen fabric is coated with an opaque, non-porous film.
Where there are patterns, to remove the opaque film, leaving a fine mesh screen, this area is where the pattern will be printed. Most commercial screen fabrics are first coated with a photosensitive film, and then the pattern is revealed by removing the film of the pattern portion by a photosensitive method. Place a screen on the fabric to be printed for printing. The printing paste is poured into the printing frame and is forced by a scraper (a tool similar to the wiper on the windshield of the car) from the mesh of the screen, through each color in the printing pattern Screen only, the purpose is to print different colors.
Example 3 Chromatic printing requires 3 frames and 3 colors are printed on the fabric. In addition, the pattern of each color in the pattern must be accurately positioned on the screen so that the position of the pattern is accurate after printing, 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 accurately printing all fabric colors on fabrics.
There are three methods for achieving screen printing, and the principle of application of each method is basically the same. The first is manual screen printing, which was common in the 1920s and is still widely used today. Until the mid-1950s, prior to modern technology giving this process automation, manual screen printing was always the only method of screen printing.
The second method is called automatic screen printing (also known as flat screen printing and automatic flat screen printing). In the mid-1960s, with further development, the shape of the screens evolved from manual and automatic flat screens to rotary screens. The third method, called circular screen printing or rotary screen printing, is the most widely used screen printing method.
