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 .
