Screen printing machines are often used in shoe material printing and T-shirt printing. Screen printing is also known as "screen printing". During printing, the ink is transferred to the substrate through the mesh of the graphic part through the extrusion of the scraper to form the same graphic as the original. Screen printing is widely used because of its simple equipment, convenient operation, simple printing and plate making, low cost and strong adaptability.

In the existing multi-color screen printing, multi-printing system and multi-station printing are adopted, that is, on one printing production line, the printing stations of each color are set cyclically, and a specific shape can be completed in one process cycle. or printing in the printing area.

A plurality of drying stations equal to the number of printing colors and a transmission mechanism, each station is set at equal intervals to form a cycle, and the printing is completed through the cycle. However, the disclosed multi-color printing machine cannot meet the needs of multiple printings for a certain color, such as multiple printing and overprint printing for a certain color or printing with different printing times for each color , you need to suspend the printing of other stations. At the same time, after printing once, you need to transfer the printed matter once between each process, and return to the printing station for the second printing. The suspension of the equipment and the printing process between The increased cost of useless transfers is unacceptable to the printer.
