Flat Screen Printing Machine

Flat Screen Printing Machine

Flat screen printing machine is an automated version of the older hand-operated silkscreen print process, used on t-shirts and other clothing. In this type of printing, the pattern is transferred to the cloth through openings in special screens that are engraved for each color in the design. A squeegee is then used to force the printing paste through these holes. In addition to a glue trough and the flat bed print table, the flat screen printing machine has a harness to lift and lower the flat screens.

The first step in the flat screen printing process is the creation of a design or image to be printed. This can be done digitally or by hand. Once the design is completed, a textile artist will convert it to a stencil or screen. The screen is then coated with a liquid photo-sensitive resin. A high-intensity light is then directed onto the screen. When the light hits the screen, the resin hardens where light is not reflected or blocked.

After the screens are ready, a fabric is laid flat on the print table. It is then glued to the flat rubber blanket. A series of flat engraved screens are then raised up and lowered onto the cloth, one at a time, in the order of the colors in the design. The squeegee then forces the printing paste through the open areas of the screen, thereby reproducing the desired pattern on the cloth.

A flat screen printer is also able to print smaller patterns that cannot be printed on a rotary machine. This includes one-pixel line, spray, and dot patterns. It is also superior to rotary screen printing in terms of image quality, as it can print fine details that would otherwise be impossible to produce with a squeegee.

This type of printing is commonly used for logo and text print on t-shirts and other garments. However, it is also used for a variety of other applications. This includes printed circuit boards and medical part prints. It can also be used to print on glass and plastic sheets.

Another benefit of a flat screen printing machine is its ability to work at high speed. This is important because it allows the screen to be exposed, printed, and removed within 30 minutes or less. This is much faster than rotary screen printing, which can take as long as two hours for a single print. Additionally, the printing process is more reliable, as the flat screen printer is able to maintain the same printing angle and pressure throughout each cycle. This is especially important for the application of fine lines and sprayed coatings. It also helps reduce the risk of damage to the print. This ensures that the end product will be of high quality. Lastly, the flat screen printer is much more economical than rotary or lithographic printers. This makes it a popular choice for businesses looking to print large quantities of small, complex designs.
