Abstract: A method for compensating substrate shrinkage during printing on a printing machine includes generating multiple image parts of a digitally available image to be produced, factoring in information on substrate shrinkage by subdividing the image using a computer, subdividing generated image parts into data blocks using the computer, saving actual positions of blocks in the digital image using the computer, calculating target positions of all blocks in the digital image using the computer by shifting the blocks away from one another by one pixel creating single-pixel-wide gaps between blocks in the digital image, copying and rearranging blocks in the digital image according to calculated target positions using the computer, calculating positions of single-pixel-wide gaps using the computer, filling gaps with digital image data of neighboring pixels using the computer to create a compensated digital image. The compensated digital image is printed on the printing machine.

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.
