Abstract
A printing apparatus including: a screen having a printing plate portion and reinforcing strips formed on both sides of the printing plate portion; a stretching device for stretching the screen by applying a predetermined tension thereto in a longitudinal direction of the strips; a squeegee for sliding on the screen in the same direction as the longitudinal direction of the strips, thereby transferring ink onto a surface subjected to printing; and a support table for supporting a material subjected to printing. The squeegee has a width larger than the minimum spacing of the strips on both sides of the printing plate portion. When the squeegee slides on the screen, it presses the printing plate portion and the strips on both sides simultaneously. In printing, the portion of the screen in contact with the surface subjected to printing is maintained flat in the transverse direction. A stretching amount of the screen in the moving direction of the squeegee is equal to a stretching amount of each strip. The screen is not damaged by deformation.
