    摘要: A method for imaging a printing form (10) using at least one controllable light source (42) is described, a number of image spots (20) being generated at a number of positions on the printing form (10) in accordance with image data in a bit field, by the controlled action of light on the printing form (10), the intensity of the light acting at at least one of the positions of the image spots (18) being controlled as a function of the value of a measure for the number of the image spots (24) to be generated in one surrounding area (22) of the position. The method may be implemented in a device for imaging a printing form (10), having at least one controllable light source (42) and a control unit (50) including a processor (52) and a memory unit (54) in such a way that a program for executing the method is stored in the memory unit (54) and may be executed in the processor (54). The device may be used in a print unit (58) of a printing press (60).

    摘要: A method for driving a printing press includes driving, in a printing operation, via a gear train by at least a first motor, at least one drum for advancing printing material and a printing-form cylinder, processing angle-of-rotation signals of the drum in a control device for controlling the driving of the drum and the form cylinder, and driving, in a printing-form production operation in the printing press, a printing-form cylinder by a separate motor. The method further includes, in an operation for producing the printing form, synchronously actuating the first motor and the separate motor by providing a gear allocated to the driving of the printing-form cylinder, and an adjacent gear allocated to the driving of the drum of the gear train, the gears being disposed relative to one another at the most out of contact with one another, and at the least barely in engagement with one another so as to exert a slight pressure on one another, and a device for performing the method.

    摘要: A write head of an imaging system for producing a printing plate can be calibrated quickly, simply and without errors. Test patterns are produced with the write head, the deviation of a property of the write head from a reference value is determined, and a corrective parameter in the write head is adjusted in order to compensate for the deviation. Test patterns that can be evaluated visually with regard to the writing quality are produced in a plurality of test fields with different parameter values, an identifier that can be picked up visually is produced with each test field, and the identifier of the test field which appears best in terms of quality is entered into a control device for the write head. The printing plate is produced by using the entry of the identifier for automatically setting the parameter value with which the best test field was produced.
