Abstract: A method for printing sheet-type substrates to prevent streaks during the ink-jet paint coating of substrates, includes moving a substrate in a feed direction past an application device by means of a conveying device, applying with the application device, during the movement of the substrate, a fluid application material drop by drop to the surface of the substrate in a pattern with a pre-defined contour, in particular leaving out regions, through a plurality of ink-jet nozzles arranged in a row transversely to the feed direction, in response to computer-controlled switching signals, and during the application of the pattern and during the movement of the substrate, moving the ink-jet nozzles back and forth transversely to the feed direction, preferably in the longitudinal direction of the arranged row of ink-jet nozzles, such that the paths travelled by the nozzles over the substrate by the overlap of the movement back and forth with the movement in the feed direction have direction components running perpendicular to the feed direction.

Abstract: 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.
