Abstract:
A screen printing method comprising:placing a material to be printed at a predetermined portion of a printing table; feeding one of a paste-state coating material and an ink-state coating material to a surface of a screen plate; coating a thickness of the one of the paste-state coating material and the ink-state coating material onto the surface of the screen plate to form a coated material layer; degassing bubbles in the coated material layer by changing a pressure surrounding the coated material layer from a high-vacuum state to one of an atmospheric-pressure state and a low-vacuum state; and printing the coated material layer onto the material to be printed by sliding the surface of the screen plate and a surface of a squeegee relative to each other while the pressure surrounding the coated material layer is at one of a vacuum state or the atmospheric-pressure state.
