Claim 0:
1. An additive printing method for printing a functional print pattern on a surface of a three-dimensional object, the method comprising the steps of:
providing a three-dimensional object on a planar surface;
providing a print head having a plurality of print nozzles, the plurality of print nozzles defining at least one print nozzle plane, the print nozzle plane being non-parallel to the planar surface;
generating three-dimensional geometrical surface data of an exposed surface of the three-dimensional object on the planar surface;
generating two-dimensional geometrical surface data of the exposed surface of the three-dimensional object on the planar surface on the basis of the three-dimensional geometrical surface data;
determining an amount of printing fluid to be discharged at a discharge time from each of the plurality of print nozzles;
generating a relative movement between the three-dimensional object and the print head; and
printing a functional print pattern on at least one portion of the exposed surface of the three-dimensional object during the relative movement,
wherein the step of generating the two-dimensional geometrical surface data includes the step of projecting the two-dimensional geometrical surface data onto the print nozzle plane to correct distortions present in the two-dimensional geometrical surface data due to the print nozzle plane being non-parallel with the planar surface, thereby obtaining two-dimensional print nozzle plane data of the three-dimensional object.
