ABSTRACT:
A mask for an electroluminescent panel has an elongated aperture through which a moving photoconductive member is exposed. To prevent elongated side strips from bowing, a connecting strip of mask material runs obliquely to the direction of movement of the photoconductive member. Portions of one or both of the elongated side strips are missing to provide additional exposure to the member to compensate for exposure masked by the connecting strip.
