PROBLEM TO BE SOLVED: To solve the conventional problem that a printing process is time- consuming because of the replacement of a mask each time a different pattern is to be printed on a different base. SOLUTION: The screen process printing machine comprises a printing table equipped with a mechanism for positioning an X-axis, a Y-axis and aθ-axis and a lift mechanism, the mask having a transfer pattern attached to a plate frame as an operating part, a camera for photographing an image of a positioning mark put on a substrate and the mask, a squeegee head equipped with a squeegee, a squeegee lift mechanism and a squeegee horizontal transfer mechanism, and a control device for controlling these mechanisms. The mask has a plurality of patterns, and each of position registering marks formed for each of the patterns and the substrate has each of position registering marks of shapes such as corresponding to each of the printing patterns. Thus, the position registering process by pattern matching is achieved. COPYRIGHT: (C)2004,JPO
