摘要:
An image-recording device for generating image spots (210) by n individually controllable light sources (12), which each have a distance si, i being=1 . . . n, to an object line (14), in a projection line (16) of the object line (14) on a printing form (28), which moves with a velocity component v normally to the direction defined by the projection line (16) and tangentially to the surface of the printing form. The image-recording device is distinguished by the triggering device (216) having an assigned time-delay device (222), which delays the tripping instant of the triggering device for each light source (12) as a function of the particular distance si. The image-recording device may advantageously by used in direct imaging print units or printing-form exposure units.
