Abstract: A method for printing endless printing substrates digitally on an inkjet printing press (1), in which first a predefined region of the printing substrate (17) is under-printed with a base tint (for example, white ink) by the print head (9) being moved to and fro in the X-direction and movement of the bridge (7) in the Y-direction. After the region which has been provided with the base tint has been advanced in the Y-direction, overprinting is carried out there, wherein once again the print head (9) is moved to and fro in the X-direction, but the printing substrate (17) is moved in the Y-direction with the bridge (7) at a standstill. In one variant, the printing substrate is moved in the Y-direction with the bridge (7) at a standstill during the under-printing and the bridge (7) is moved in the Y-direction during the overprinting. The under-printing and overprinting can take place once or multiple times.

Abstract: Process for the processing of image data which represent the color values of an image, to achieve optimal color reproduction of the image by an image reproduction system, especially by a photographic printer or photolab in response to the image data. In an exemplary embodiment, the image data which represent first positions in a first color space are received. The first positions are transformed into transformation positions which represent positions in a second color space; and the response of the image reproduction system to the image data is modeled with a model image reproduction system such that the model image reproduction system outputs the response as model positions which represent the color values produced by the model image reproductions system in response to the input of the image data as positions in a second color space.
