Offset printing apparatus

Abstract

On a guide rail (2) provided on a mount (1), there are travelably provided a plate table (3) and a substrate table (4). On the tables (3, 4), there are respectively installed alignment stages (6, 8), on which a plate (7) and a substrate (9) are respectively held. At required locations on the mount (1), there are provided separate alignment areas (15, 16) respectively for the plate (7) and the substrate (9). In the alignment areas (15, 16), the position of the plate (7) held on the plate table (3) and the position of the substrate (9) held on the substrate table (4) are subjected to an initial alignment, to thereby correct the positions so that the plate (7) and the substrate (9) squarely face the center of axle of a blanket roller (11) in the same relative arrangement with respect. As a result, reproducibility of the printing pattern that is printed from the plate (7) onto the substrate (9) via the blanket roller (11) is improved.
