ABSTRACT:
A photosetting apparatus has a segment (11) of a regular cylinder consisting of aluminium in the interior of which a sheet-like photosensitive material (12) is mounted with the photosensitive layer directed inwardly. A rotary mirror (38) arranged on a carriage is illuminated axially by a laser beam and scans the photosensitive material (12) in the circumferential direction while the carriage is advanced axially. The photosensitive material (12) is brought into contact with the inner side of the segment (11) over its full area by compression in the circumferential direction. The photosensitive material (12) is guided by two guide rings (23) which can be arranged at different spacings within the segment (11).
