<p>An imagesetter of the 'internal drum' type for producing an image on a flexible section of photosensitive material does not actually have a drum (10). Instead, the photosensitive material (30) is supported in a cylindrical shape by spaced internal disks (32, 34). The flexible photosensitive material (30) is held in position to pass around the periphery of the disks (32, 34) by rollers (38, 40, 44, 46). In some cases the flexible photosensitive material (30) may be supported by a sheet of flexible, but relatively rigid material (66).</p> |
