The invention relates to a method for printing on a substrate by inkjet printing. The aim of the invention is to devise a method for printing on a substrate by way of inkjet printing, which method allows a substrate to be printed on efficiently and simply, with the printing result being particularly uniform and without unwanted artefacts and in particular the printed surface being free from visually noticeable different zones. According to this method, landing zones are provided on the substrate in a landing zone pattern consisting of landing zone columns and landing zone rows, and the landing zones are each printed on, using an individual pattern consisting of at least two droplets, by means of print head nozzles of at least one print head, and the print head nozzles and the surface of the substrate are moved relative to one another, in particular along an imaginary nozzle path, during printing. The droplets are printed within at least a part of the individual patterns, preferably within each of the individual patterns, such that any mutual influence of the droplets within an individual pattern on the substrate is counteracted.

Method and device for printing on a substrate by way of inkjet printing

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.

The invention relates to a surface machining device comprising a substrate support for receiving a substrate to be machined, a machining unit which can be moved relative to the substrate support along a first and a second movement axis, a position detecting unit for ascertaining the orientation of the substrate, and a control unit for controlling the movement of the machining unit dependent on the orientation of the substrate on the substrate support. The aim of the invention is to provide a surface machining device which can be produced in a compact manner and which allows a precise machining of the surface of the substrate to be machined in an inexpensive manner regardless of the position of the substrate on the substrate support. This is achieved in that the machining unit can be pivoted relative to the substrate support, in particular about a height axis which extends perpendicularly to the plane formed by the first and second movement axis.
