A printing apparatus applies material to a carrier through a planar screen having a pattern including a number of lines substantially parallel to a first direction. The screen and carrier are mounted so material forced through the lines of the screen is deposited on the carrier in the same pattern as the pattern of the screen. A blade having an elongated, straight edge is positioned to force the material through the screen onto the carrier. The blade is supported and actuated so that the blade is displaced in a plane parallel to the plane of the screen and in a second direction. The second direction is adjustable to any angle with respect to the first direction, so that the blade can slide parallel to the lines in the screen. |
