Abstract
A method of printing a print material on a surface of an object by placing the print material on a surface of a print mask having a plurality of holes, positioning the print mask relative to the object such that the print mask is near, and substantially parallel, to the surface of the object, moving at least one of a squeegee and a first combination of the print mask and the object relative to the other of the squeegee and the first combination, in a print direction along the surface of the print mask, while locally pressing, with the squeegee, the print mask against the surface of the object and pressing, with the squeegee, the print material along the surface of the print mask, so that a portion of the print material is printed on the surface of the object through the holes of the print mask, the method including the steps of locally pressing, with a mask-press member, the print mask against the surface of the object, at a position distant from the squeegee by a predetermined distance which assures that the mask-press member does not contact the print material being pressed by the squeegee, and moving at least one of a second combination of the squeegee and the mask-press member …
