As a distance a1 ; a2 ; a3 In this case, the length of the shortest connecting line between the respective position of the ink outlet opening applies in each case 53 and the pixel to be printed on the substrate surface. An inkjet printer 51 has at least one inkjet printhead with z. B. one thousand or more arranged in the same plane ink jet nozzles 52 on, with per millimeter printhead width z. For example, five to fifteen or more ink jet nozzles 52 are arranged. In an inkjet printer 51 can also be several inkjet printheads, preferably each of the same construction described above, preferably in the same plane z. B. arranged in a row. Like in the 9 exemplified, are in a body 07 with an at least partially curved and / or arched and / or convex lateral surface 54 a plurality of pixels of the printing image to be printed on the printing material surface just not arranged in a same plane.

B. a difference of at least 0.5 mm, more preferably at least 1 mm or more. These differences in the mentioned intervals a1 ; a2 ; a3 can in a conventional inkjet printing 51 lead to a visible reduction in print quality. The printing width of the printing surface to be printed on the printing substrate surface, having a plurality of pixels, extends parallel to the print head width of generally several inkjet nozzles 52 having inkjet printing unit 51 ,

Thereafter, the various individual results are converted into a total result, which shows the different distances a1 ; a2 ; a3 considered. This is done for each relevant in the printing process distance a1 ; a2 ; a3 first create your own profile. The profiles of all these distances a1 ; a2 ; a3 are each optimized so that all these profiles produce the same visual impression to a viewer. Then the data processing device processes 56 the data, e.g. B. image data by means of an algorithm taking into account the respective distance a1 ; a2 ; a3 , This second embodiment is computationally easy to implement and is just in consideration of the color management very beneficial.
