The present invention provides a method of attaching a tension mask to a frame to achieve desired tensions at a plurality of locations across the mask, wherein the frame has two opposite sides between which the mask is to be attached. Specific forces are applied from each of a plurality of separate actuators at positions, along each of the two opposite sides of the frame, that affect the mask tensions respectively at the plurality of locations across the mask. Each of the actuators is individually controlled to apply a specific force to a frame side that is directly related to the desired mask tension required at a particular mask location. While the specific forces are applied by the actuators, the mask is attached to the two opposite sides of the frame. Thereafter, the forces on the sides are released.
