  • Screen printer and a screen printing method
    Patent number: 6176179
    Abstract: The present invention aims to achieve a screen printer which will not result in uneven printing which may occur depending on the printed positions. The moving position of squeegee is detected by the sensors. The pressure control unit adjusts a degree of opening and closing the valve depending on the moving position of squeegee, and adjusts the pressure P generated by the air cylinder. By decreasing the pressure P at center and increasing the pressure P at both edges of a work, the work is printed without any unevenness.
