A method for printing sheet-like substrates, wherein - a substrate is moved past an application device along a feed direction , by a conveyor device ; and - while the substrate is moved, the application device applies, drop by drop, a fluid application material onto the surface of the substrate in a pattern with a predetermined contour , in particular by sparing areas , using a plurality of inkjet nozzles that are arranged in a line transverse to the feed direction, in response to computer-controlled switching signals; wherein - while the pattern is applied and the substrate is moved, the inkjet nozzles are reciprocated in the direction transverse to the feed direction , preferably along the longitudinal extension of the line array of the inkjet nozzles , so that the paths the nozzles cover over the substrate have directional components perpendicular to the feed direction , due to the superposition of the reciprocating movement with the movement along the feed direction ; wherein a fluid organic coating material is applied as the fluid application material, and wherein, once applied, the film is cured to form a solid polymer coating ; and wherein an amplitude of the movement of the inkjet nozzles transverse to the feed direction is not greater than five times the nozzle spacing and is at least equal to a single nozzle spacing as measured from the centre of one inkjet nozzle to the centre of an adjacent inkjet nozzle ; and wherein the coating pattern is defined by an array of adjacent target areas , wherein a computer determines which one of the inkjet nozzles comes closest to or best matches a target area during the movement of the substrate on the one hand and the periodic movement of the inkjet nozzles on the other hand, and sends a control signal to this inkjet nozzle so that the nozzle dispenses a drop of the fluid organic coating material to said determined point closest to or best matching the target area . - a substrate is moved past an application device along a feed direction , by a conveyor device ; and - while the substrate is moved, the application device applies, drop by drop, a fluid application material onto the surface of the substrate in a pattern with a predetermined contour , in particular by sparing areas , using a plurality of inkjet nozzles that are arranged in a line transverse to the feed direction, in response to computer-controlled switching signals; wherein - while the pattern is applied and the substrate is moved, the inkjet nozzles are reciprocated in the direction transverse to the feed direction , preferably along the longitudinal extension of the line array of the inkjet nozzles , so that the paths the nozzles cover over the substrate have directional components perpendicular to the feed direction , due to the superposition of the reciprocating movement with the movement along the feed direction ; wherein a fluid organic coating material is applied as the fluid application material, and wherein, once applied, the film is cured to form a solid polymer coating ; and wherein an amplitude of the movement of the inkjet nozzles transverse to the feed direction is not greater than five times the nozzle spacing and is at least equal to a single nozzle spacing as measured from the centre of one inkjet nozzle to the centre of an adjacent inkjet nozzle ; and wherein the coating pattern is defined by an array of adjacent target areas , wherein a computer determines which one of the inkjet nozzles comes closest to or best matches a target area during the movement of the substrate on the one hand and the periodic movement of the inkjet nozzles on the other hand, and sends a control signal to this inkjet nozzle so that the nozzle dispenses a drop of the fluid organic coating material to said determined point closest to or best matching the target area . <EOS>
