A screen printing method includes the steps of moving a doctor plate across a printing screen to apply a paste thereon and then moving a squeegee across the screen to deposit a paste on an object below the screen while maintaining a predetermined pressure of the screen against the object to produce a substantially even deposition of the paste. The method also can include varying the squeegee pressure as the screen tension varies to maintain the predetermined printing pressure and using a screen aligning mark on an imaging plane to correct the positional relationship between the screen and the object.

Screen printing method comprising printing pressure regulation

A screen printing apparatus capable of uniformly applying a paste onto a screen to accomplish fining of a printed pattern and formation of a fined printed pattern. The apparatus includes a pair of laterally movable printing heads alternately actuated for printing and each including a doctor plate and a squeegee which are vertically movably arranged. The doctor plates of the printing heads being arranged laterally opposite to each other on the screen. The doctor plates each serve to apply a paste onto the screen while transferring the paste on the screen and the squeegees each act ot press the screen against a printed object after application of the paste onto the screen by the doctor plate corresponding thereto.
