Abstract
Method of exposing a light sensitive member with a discharge lamp energized by an alternating electrical current where the exposure time for each point on the light sensitive member is an integral multiple of the period of the periodic output variations of the discharge lamp. In the preferred embodiment, the exposure is effected through a slit where relative movement occurs between the slit and the light sensitive member and where l = v .multidot. n To, l being the width of the slit, v being the relative velocity between the slit and light sensitive member, To being the period of the periodic output variations of the discharge lamp and n being any positive integer.
