Abstract: The invention relates to a system (21) for transferring data to disk-like data storage media (23, 23?), which system comprises a pick-up (22, 22?) which is at least partially in the form of an inner cylinder and is intended to arrange the data storage media—the side of which that is intended to receive data faces the cylinder axis (29) of the pick-up—and a transfer head (30) which can be rotated about this cylinder axis and has at least two transfer means (24, 24?) for transferring the data to the data storage medium (23), wherein the pick-up (22, 22?) and the transfer head (30) can also be moved relative to one another in the direction of the cylinder axis (29), and the at least two transfer means (24, 24?) comprise a respective array of light sources in order to transfer the data using multi-beam technology.

Abstract: An internal-drum imagesetter for transferring data to disc-like data storage media has a pickup for arranging the data storage media and a transfer head having at least one transfer means for transferring the data to the data storage medium. In this case, the pickup is advantageously at least partially cylindrical in shape. The side of the data storage medium which is provided for picking up datafaces the cylinder axis of the pickup. The pickup and the transfer head can move relative to one another such that the transfer head can move in the direction of the cylinder axis of the pickup and is arranged so as to be able to rotate about the cylinder axis of the pickup. The transfer means are in the form of violet high-power laser diodes with a wavelength of 405 nm. In addition, the laser diodes are arranged in an easily replaceable laser diode arrangement and they can also be easily replaced individually. This internal-drum imagesetter can also be used to expose conventional offset plates.

Abstract: An exposure device for the production of screen-print stencils has a holder for the stencil, an exposure system with a light source, and a lens system in an exposure head that is movable. A signal source that yields digital signals is connected with the exposure system. The light source is a number n of laser diodes that work in the wavelength range of 300-450 nm. Several modules comprising groups of laser diodes are present on the exposure unit and can be controlled by the signals of the signal source. The light signals of the laser diodes are guided to a raster plate in the exposure head, by light-guiding fibers. The light output of the raster plate is passed to a focusing lens system in the exposure head, which is adapted to the laser diodes in terms of the wavelength range.

Abstract: The invention relates to a device, a method and a corresponding computer program product for transmitting data to a carrier. The device (1) comprises a control system (2), a holding surface (3) which is used to hold the carrier (4) and a transmission head (5) for transmitting data from a data memory (6) to said carrier (4). The holding surface (3) is arranged in such a way that it can be rotated about an x-axis (8) by means of a first drive device (7) and the transmission head (5) is arranged in such a way that it can be moved along a y-axis (10) by means of a second drive device (9). Both the holding surface and the transmission surface are controlled by the control system (2) in a coordinated manner.

Abstract: In order cost effectively and in spite of the lowest possible expenditure on construction to permit the logical provision of printing plates of different types and sizes for an extremely wide range of printing plate exposers, in an apparatus for loading and/or unloading an exposer, in particular a drum exposer, with printing plates, having a suction means comprising at least one sucker plate and at least two suction heads connected to a vacuum system for picking up printing plates, in particular thermal printing plates, and a pivoting device for pivoting the suction means, it is proposed that the sucker plate be constructed in the form of a cylindrical segment and the suction means be pivotable about an axle which is arranged substantially parallel to the axis of the cylindrical segment.

Abstract: A system (21) is proposed for transferring data to plate-like data carriers (23, 23′), the system comprising a holder (22, 22′), shaped at least partly as an inner cylinder, to arrange the data carriers (23, 23′)—of which the side provided to accept data faces the cylinder axis (29) of the holder (30)—and a transfer head (30) which can rotate about this cylinder axis and has at least one transfer means (24)—for transferring the data to the data carrier (23, 23′) the holder (22, 22′) and the transfer head also being capable of moving relative to each other in the direction of the cylinder axis (29) and the distance between at least one surface of the transfer head (30) or transfer means (24) and the data carrier—during the transfer of data—preferably being less than ¼ of the holder diameter and particularly preferably less than 1 cm.

Abstract: For the production of a printing stencil, a fine-mesh screen is provided with an unexposed photoemulsion layer and aligned in order to establish it in an essentially tubular or flat shape On the photoemulsion layer, those locations which are not to be exposed are covered with an opaque layer according to a particular pattern. The opaque coating layer--together with the non-exposed portions of the photoemulsion layer--is removed after the exposure of the non-covered locations of the latter. The opaque coating material contains wax and preferably is soluble in water. To avoid a perceptible starting line in the case of a tubular screen, the pattern start is varied according to any law, preferably following a sine line, in order to avoid a clear-cut separating line.

Abstract: A method of encoding data, involves the steps of comparing an input image from a video camera with an image being built up, and stored in store. The images are processed by an analyser in accordance with a plurality of different algorithms stored in a store to produce a plurality of different data packets each representative of a partial change which can be effected to the image to be built up to bring it closer to the input image. The analyser compares the effects of the different data packets if implemented on the data image to be built up and provides each one with a score in accordance with a predetermined criteria. A comparator selects the packet with the best score under the predetermined criteria and uses it to alter the image in the store accordingly. The cycle is repeated to cause the image to be built up, to progressively converge on the input image.
