Claim:
1. A method for printing an object using a color image printer that applies colorant dots having a flat shape, the object having an apparent surface with a locally varying color for representing a color image on the surface, the printer comprising a white colorant, that is applied as a background underneath a surface colorant for begetting a local color of the apparent surface, the method comprising the steps of: a) generating two-dimensional image data for composing the object in slices; b) determining a local surface orientation of the apparent surface of the object; c) applying colorant material in accordance with the two-dimensional image data, wherein the composition of the colorant material is dependent on an angle between the colorant dots and the local surface orientation, wherein white colorant dots are deposited between other colorant dots to compensate a color effect of an orientation of a surface colorant dot relative to the local surface orientation, and wherein a number of white colorant dots between other colorant dots is augmented if an angle between the local surface orientation and a direction perpendicular to the applied slices increases.
