Claim 1:
2. A three-dimensional (3D) color printer for printing 3D color objects layer-by-layer, the printer comprising:
a specification input for obtaining a 3D CAD file defining a 3D geometry and a color texture for said color object;
a region definer configured to divide said 3D geometry into a core and a color shell, and further to divide said color shell into volumetric regions;
an assigner configured to assign, based on a look up table (LUT), each of said regions with an arrangement of voxels in a color stack, which arrangement results in an optimal reproduction of the requested color;
an error determination unit, for determining, based on said 3D geometry, conflicting instances in which the color stack of one region interferes with a color stack of another region; and
a corrector associated with said error determination unit configured to apply a color correction in case of conflict between color stacks wherein the 3D color printer is configured to print using said color correction.
