Abstract
A method and an apparatus for adjusting devices (1, 1′) for generating color separations (2, 2′) in a multicolor printing machine (3), changes in the dimensions (4, 4′, 5, 5′) of printing substrates (6) being taken into account by controlling the image generation. Changes in the dimensions (4, 4′, 5, 5′) of printing substrates (6) during or after printing are to be taken into account as early as during the image generation. The fiber orientation (7) of printing substrates (6) is registered and, on the basis of the fiber orientation (7) and values from experience (8, 8′, 10, 10′, 10″) of the behavior of printing substrates (6) depending on the fiber orientation (7), control being carried out before the start of printing.
