Claim 0:
1. A three-dimensional (3D) color printer for printing 3D color objects layer-by-layer, the printer comprising:
a specification input for inputting a 3D CAD specification defining a 3D geometry and a surface color distribution for said color object;
a region definer for defining regions on a surface of said color object;
a color definer for defining colors for each region based on said surface color distribution;
an error determination unit for determining, using said 3D geometry, conditions applying at respective regions that are liable to cause color variation, such that using said colors as defined at said respective regions may give rise to a coloration error;
a selector, for selecting color corrections defined for respective determined conditions; and
a corrector for correcting said defined colors using said defined corrections, to compensate for respectively corresponding coloration errors;
wherein said printer is configured to print said 3D color object using respective corrected defined colors at each region.
