The basic principle that the mesh of the image-text part of the screen plate can be penetrated by ink and the mesh of the non-image-text part can not be penetrated by ink is utilized for printing. When in printing, ink is poured into one end of the screen printing plate, a certain pressure is applied to the ink part on the screen printing plate by the scraping plate, meanwhile, the ink moves at a constant speed towards the other end of the screen printing plate, and the ink is extruded onto a printing stock from the mesh of the image-text part by the scraping plate in the moving process.
The structure of a screen printing mechanism on the market is shown in fig. 1 and comprises a rigid support frame 3 for supporting a printing screen 5; a pair of parallel spaced apart linear bearings 7 mounted to the support frame 3 on opposite sides of the printing screen 5; a print carriage 9 comprising a carriage 11 supported on linear bearings 7, and a print head assembly 15 mounted to the carriage 11, the print head assembly 15 being operable to print a print medium through a pattern of print apertures in a printing screen 5 onto a workpiece supported under the printing screen; and a drive unit 17 for reciprocally driving the print carriage 9 along the linear bearings 7 in the direction D1, D2, the drive unit comprising a drive motor 19 and a toothed belt 21 connected to the print carriage 9.
