A system for aligning a mask and a product with high precision, featuring a means for supporting a product in a fixed position and a mask adjacent to the product so that the mask is movable relative to the product. The mask is surrounded by a rectangular mask frame. At least one movable first plunger presses against a first edge of the mask frame, while two movable second plungers press against a second edge of the mask frame, where the first and second edges are perpendicular. A first computer-controlled movable push plate is designed to push the mask frame against said at least one movable first plunger; pushing the mask frame in a first direction. Two second movable computer-controlled plates are designed to move the mask frame in a second direction by pushing the mask frame against the two movable second plungers. The two second movable computer-controlled push plates may also be used to rotate the mask frame by moving one of the second movable push plates toward one of the movable second plungers, while controlled simultaneously moving the other of the second movable push plates away from the other of the movable second plungers. A computer is used to determine the relative position of the mask and the product prior to alignment; and that, to achieve proper alignment of the mask and the product, the mask must be moved in the first direction by a first distance, moved in the second direction by a second distance, and rotated by a defined amount. The computer then signals the first computer controlled movable push plate to push the mask frame in the first direction by the first distance; and also signals the two second computer-controlled movable push plates to push the mask frame in the second direction by said second distance. If rotation of the mask is required, the two second computer-controlled movable push plates are signaled to rotate the mask frame by said defined amount.
