Abstract: A new testing means and process for determining typographic parameters were developed. The present invention pertains to a pattern of recorded dots, so-called dots, which is reduced such that it is nearly invisible to the observer. This test target is microscopically enlarged and preferably recorded by means of a CCD camera. The signal-to-noise ratio of the measurement is advantageously increased by averaging over a plurality of consecutive printed patterns. Using highly developed image analysis, it is possible to determine the typographic parameters directly from the miniaturized patterns. The measures taken to reduce the test target are described. The application to the type of a process control, which is based essentially on the geometric features of a certain dot pattern, is then schematically outlined as an example.

Abstract: A metering strip for an ink fountain of a printing press for metering printing ink, especially a doctor blade, is fastened in a pivoting mount and has a cylindrically shaped edge with a radius in the range between 0.3 and 1.5 mm. The edge is pressed against an inking roller and forms a metering nip with this roller for the printing ink to be metered. Axial recesses merge on both sides of the metering strip with the cylindrically shaped, wear-resistant edge that covers an angular range of more than 180.degree..

Abstract: The present invention pertains to a process for setting the halftone dot sizes for a rotary offset printing machine, in which average set values based on production technical situations are predetermined for the halftone dot sizes of the printing block, the printing characteristics of the rotary offset printing machine are detected, and compensation measures are introduced in the case of deviations in the printing characteristics from set values; in order to improve the reproduction accuracy, the average set values of the halftone dot sizes are varied in the manner of inking system for setting the individual inking systems of the rotary offset printing machines in the preparation of the printing block, taking into account the deviation trends of the evidenced printing characteristics; as an alternative or in addition, color separation images of the printed original are displayed on the image screen of a color simulation computer; the halftone dot sizes of the color separation displays on the image screen are

Abstract: A pallet feeder for a manufacturing plant or fabrication system wherein pallets are fed along a substantially circular-shaped track or path of travel. A number of transfer stations or locations are provided at which the pallets are infed and outfed essentially at right angles to the circular-shaped conveying path or track. At the center of the circular-shaped pallet feeder there is located a pallet displacement device which is pivotable about the axis of the circular-shaped track into a position coacting with the different transfer stations or locations, in order to be able to move the pallets towards and away from the conveying or conveyor track.
