(1) Working cycle program of flat screen printing machine. Take the flat screen type flat-type monochrome semi-automatic hand surface screen printing machine as an example. Its working cycle is: feeding piece → positioning → falling plate → falling to the ink plate, rising back to the ink plate → scraping stroke → rising to ink Plate → return to the ink board → lift the plate → return ink stroke → release the positioning → receive the piece.
In the continuous cycle action, as long as the function can be realized, the time occupied by each action should be as short as possible to shorten each work cycle and improve work efficiency.
(2) Imprint line. In the printing process, the ink is pressed against the ink plate and the screen printing plate, so that the screen printing plate forms a contact line with the substrate, which is called an embossing line. This line is at the edge of the squeegee, and numerous embossed lines form the printed surface. Achieving an ideal embossing line is difficult because the printing stroke is a dynamic process.
