Image setting apparatus having drum simulating supports

摘要

An image setting apparatus produces an image on a flexible section of imageable material. The apparatus includes a retainer for retaining the flexible section in a cylindrical configuration about a cylinder axis. An imageable surface of the section faces inwardly toward the axis. The apparatus includes an imaging source for selectively exposing the inwardly-facing imageable surface to produce the image. The retainer includes a plurality of arced supports spaced from each other along the axis. Each support has a curved surface segment for physical contact with an outwardly-facing surface of the section.
