Patent ID: 11148436

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.
