Abstract
A film transparency (7) is held by centrifugal force with its emulsion side in contact with the inside of the transparent drum (1) of a rotary drum scanner (1, 2, 3) used in a graphic reproduction process. A transparency locator is in the form of either an insert (4) or a clip device (20) and serves to hold the film transparency in position until the drum is rotating at a sufficiently high speed.
