Screen printing method and device therefor

Abstract

A printing object surface has a cross-sectional shape curving along a printing advancing direction. The printing advancing direction is defined as a Y-axis, a direction orthogonal to the Y-axis and belonging to the cross-section is defined as a Z-axis, and a direction around an axis orthogonal to a Y-Z plane is defined as a θ-axis. A squeegee is disposed so as to be movable in the respective Y-, Z- and θ-axis directions. Information indicating a mutual relationship among respective Y-, Z- and θ-axis positions is obtained. The relationship is a relationship that enables performing printing while maintaining or substantially maintaining an angle formed by a direction tangent to a printing position in the printing object surface in the Y-Z plane and the squeegee. Printing is executed while the respective Y-, Z-, θ-axis positions of the squeegee relative to the printing object surface are controlled according to the obtained information.
