A printing system and method of printing an object having a surface (36) of varying height, by a printer configured to print a number of pass images (1; 2; 3; ...) on top of each other in a number of passes, including: deriving (S12) from an object image a number of pass images (1; 2; 3; ...) to be printed on top of each other, including: establishing (S28; S40) pass pixels of the pass images for which pass pixels a pass pixel height is defined, wherein a sum of the defined heights of a sequence of pass pixels that corresponds to a respective pixel (A; B) of the object image equals the height of that pixel of the object image; and printing the pass images (1; 2; 3; ...) on top of each other. An amount of printed material that is printed per printed pass pixel is varied in accordance with the defined pass pixel heights. The pass pixels heights are selected S26), based on random data, from a respective set of at least two positive pass pixel heights. |
