  • Method for correcting skewed recording when exposing printing originals
    Patent number: 7330202
    Abstract: A method for correcting the skewed recording of a printing original on a recording material in an exposer includes the steps of projecting, with an exposure head, a linear array of exposure points generated by N laser beams onto the recording material and moving the exposure head continuously along an exposure drum in axial feeding direction as the exposure drum rotates. As a result, the printing original is recorded along a helix wound around the exposure drum. The laser beams are modulated with image data that is taken from a stored image point matrix along an angled read path, the read path running through the image point matrix at an angle formed by the helix with respect to a circumferential line of the exposure drum.

  • Method for setting a device for image reproduction on printing plates
    Patent number: 7324131
    Abstract: A method sets up a device for image reproduction on printing plates. The fastening of image reproduction members, their orientation and tolerances, and also tolerances in the positioning of the image reproduction members on a guide or a spindle, lead to mis-positions of the image reproduction members in relation to one another. Offsets of two adjacent image parts may occur. In the method, the printing plate has reproduced on it in the X-direction at least one first pattern which overlaps with the first pattern of an adjacent image reproduction member and/or the printing plate, in each case with a right and a left column, has reproduced on it in the Y-direction in each case at least three spaced-apart second patterns, such that in each case the right column of an image part is at least contiguous to the left column of an adjacent image part.
