    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.

    摘要: A method and a device for imaging a printing form (48) via at least two imaging modules (40,418) which each have at least one light source are disclosed for avoiding the banding effect that an imaging in a transition region (416). The two imaging modules (40,418) are provided in such a manner that a number of at least partially not-simply connected printing dots are produced in the transition region (416) by the first imaging module (40) and the complementary, not-simply connected printing dots are produced in the transition region (416) by the second imaging module (418).

    摘要: A device determines the positional deviation of n points (P) from their reference positions using a source of electromagnetic radiation (1), imaging optics (2, 4, 9), and a photosensitive detector (10), which converts the positional information into information on intensity. Simultaneous or concurrent in time n signals are produced by the detector (10), each of the n signals being uniquely assigned to one of the reflection points (P). The generated signals can be used to control an autofocusing device or to control the intensity of light sources in devices for imaging printing forms.

    摘要: A printing form that can be used many times has a printing surface which is provided with a metallic titanium layer. For imaging, the printing form is selectively coated hydrophilically in point-by-point manner by supplying controlled energy. After the printing, the image on the printing form can be erased by supplying heat; a method for forming images on a printing form and for erasing them; and a printing unit and a printing press including the printing form.
