Abstract (en)

[origin: WO2020043463A1] The invention relates to a method for setting the layer thickness of a covering coating material to be applied to a substrate (13) by an application device (04), wherein: the coating material is applied to the substrate (13) in a printing machine or in a paper-processing machine; the coating material is applied at various points on the substrate (13) in question by means of the application device (04) in a machine process; at each of at least one first point on the substrate in question (13), the coating material is applied in a grid having a plurality of grid points, and at each of at least one other second point on the substrate (13) in question, the coating material is applied over the full area; each first point in question on the substrate (13) in question forms a grid zone and each second point in question on the substrate (13) in question forms a solid zone; a control unit (06) connected to a sensing device (12) determines respective values for the optical density of the layer of the coating material applied at the points in question on the substrate (13) from data captured by the sensing device (12) at the first and second points on the substrate (13) in question; the control unit (06) defines the layer thickness of the coating material currently applied to the substrate (13) in question by the application device (04) in the ongoing machine process, at which layer thickness the value of the optical density determined in a grid zone corresponds to the value of the optical density determined in a solid zone, as the layer thickness of the coating material having an opacity of 100%.
