  • Publication number: 20240408891
    Abstract: The invention relates to a method for printing on a substrate by means of inkjet printing, in which method landing zones are provided on the substrate in a landing zone grid consisting of landing zone columns and landing zone rows, and the landing zones are each printed on using an individual pattern consisting of one or more drops by means of one or more print head nozzles of a print head, wherein the print head nozzles are moved over a surface of the substrate along an imaginary nozzle path during printing. The invention also relates to a device for printing on a substrate comprising a landing zone grid consisting of landing zone columns and landing zone rows by means of inkjet printing.

  • Patent number: 10981394
    Abstract: 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.
