According to an example aspect of the invention, there is provided a method for producing a heating system on a 3D plastic window such as a car window of plastic, comprising an electric heat conductor structure consisting of at least two bus bars (principal heat conductors) and a grid line pattern with a plurality of grid lines (branch heat conductors), comprising n a step, in which the two bus bars are respectively screen-printed onto the 3D plastic window, preferably on the edges of the latter, by means of at least one displaceable squeegee with screen-printing ink in the form of a first electrically conductive paste, preferably a first silver paste,n na step, in which the grid line pattern is applied onto the 3D plastic window such that it respectively overlaps the two bus bars with at least one second electrically conductive paste, preferably a second silver paste, which has a greater electrical resistance than the first electrically conductive paste, andn na final step, in which the two bus bars and the grid lines overlapping these bus bars are at the respective overlapping points electrically connected into the electric heat conductor structure by means of electrical connectors. |
