    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.

    摘要: A device for spotwise imaging printing surfaces includes a laser light source producing at least one laser beam movable relative to a printing surface, the laser beam defining an image spot on the printing surface, the laser beam having a laser power. A laser control varies the laser power or an exposure time as a function of a distance of the laser light source from the image spot.

    摘要: An imaging method for a printing form (32) is described, with one or more laser diode bars (10) with n individually controllable laser diodes (12) each of which are assigned to one imaging channel, in which the laser diodes (12) of a laser diode bar (10) are divided into a main field (14) of m and into an auxiliary field (16) of (n-m) laser diodes (12) in such a way that an imaging channel (44) in the auxiliary field (16) with a matching feed that can be activated is assigned to each imaging channel (44) in the main field (14) that cannot be activated. In order to create a row (40) of m printing dots (38) on a setting line (36) at even distances a by means of the imaging channels (44), printing dots (38) are set by the main field (14) at a first time, and by the auxiliary field (16) at least at a second time. The imaging channels (44) are shifted relative to the printing form (32) parallel to the setting line (36) between the imaging times. Also, a method for the determination of the largest possible main field (14) with imaging channels (44) that under the circumstances cannot be activated is provided.
