Image printing arrangement

摘要

The arrangement consists of a light source, whose light affects partially a layer of a print form, according to data representing an image to be printed. The light is led onto the form over light conductors with the help of an arrangement for the control of light. The layer comprises a lasting affinity to the ink through the influence of the light. An arrangement is provided for the movement of the print form relative to the light conductors, so that the light records the entire surface of the print form. Several optic fiber bundles (5, 13, 21-24) are provided as the light conductors, at which the relative position of the fibers (29) at both ends (25-27) is respectively equal. The fiber ends (25) which face the layer of the print form (1) are arranged as bundles along at least one line crosswise to the movement direction of the print form. The fiber ends (26) which face the light source (9), are arranged along a line for each fiber bundle, and are layered on a plane (6). An arrangement (7, 14, 20, 34) for controlling of light is coupled before the fiber ends on the plane, which release light for each image element, according to data representing the image to be printed.
