The object of the invention, which relates to a method for printing a substrate by means of inkjet printing, is to enable precise printing of a landing point matrix, which is displaced, rotated, or distorted, particularly not linearly distorted, as compared to an ideally orthogonal landing point matrix, with less complexity. Said object is achieved in that the lateral resolution is selected to be large enough that the smallest distance between nozzle lines is less than the minimum distance between the landing zone rows, and that, with a variation, specified by the substrate, of the distance of adjacent landing zone rows between various landing zone lines (distortion), the position of the landing zones of a landing zone line is determined relative to the nozzle lines and consequently only the printhead nozzles having a nozzle line intersecting a landing zone are actuated according to a nozzle actuation scheme and the corresponding landing zone type.
A method for printing a substrate by means of inkjet printing, wherein landing zones, which correspond to a landing zone type, are specified on the substrate, in a landing zone matrix consisting of landing zone lines and landing zone rows aligned vertically thereto, the landing zone matrix is aligned relative to the print head such that the landing zone rows extend essentially parallel to the print direction, and the actuation of the print head is carried out such that one or more drops of one or more printhead nozzles create a pattern of landing points within the landing zone, wherein the printhead nozzles create imaginary nozzle lines on the substrate surface with a lateral resolution representing the distance between the nozzle lines, characterized in that the lateral resolution is selected to be large enough that the smallest distance between nozzle lines is less than the minimum distance between the landing zone rows, and that, with a variation of the distance of adjacent landing zone rows between various landing zone lines specified by the substrate, the position of the landing zones of a landing zone line is determined relative to the nozzle lines and consequently only those printhead nozzles the nozzle line of which intersects the landing zone are actuated corresponding to a nozzle actuation scheme and the corresponding landing zone type.
