A method produces a printing image formed of sections on a material using two inkjet printing heads. The printing image has first and second printing image sections meeting at a y coordinate Y1. The method includes choosing a data stripe extending in the x direction having a width about the location Y1, and examining the data in the selected stripe for a data field of the extent dx in the x direction and dy in the y direction, in which edge detection is possible. The data field is selected and the x coordinate x1 and the y coordinate y1 of the data field are captured. The printing image is then produced. An image of a measurement field correlated to the data field is recorded. The image is recorded, and edge detection is carried out. The image is corrected when an edge is detected.
