First Claim
1. A method of printing a three-dimensional object onto a base using a printing system, the method comprising:
- receiving at the printing system;
a first target thickness for a first region of the three-dimensional object;
a predefined structural layer thickness for a printed layer; and
color layer information for each of a first color layer and a second color layer;
receiving the base at the printing system;
calculating a number of structural layers to be printed to achieve the first target thickness for the first region based on the predefined structural layer thickness;
printing the first color layer onto the base using the received color layer information for the first color layer;

printing the second color layer onto the set of structural layers using the received color layer information for the second color layer;
wherein the set of structural layers is transparent and the second color layer is partially transparent, such that light from the first color layer passing through the set of structural layers and through the second color layer creates a three-dimensional visual effect that is based at least in part on the first target thickness;
wherein a set of structural layers in a second region that is adjacent to the first region is printed to achieve a second target thickness that is different than the first target thickness, and a set of structural layers in a third region that is adjacent to the second region is printed to achieve a third target thickness that is different than the first target thickness;
the method further comprising receiving the second target thickness for the second region and the third target thickness for the third region at the printing system, and printing the set of structural layers in the second and third regions to achieve the second and third target thicknesses for the second and third regions;
wherein the set of structural layers in the first region, the second region, and the third region are arranged to collectively form an upper surface having a surface contour.

Abstract
A method of printing a three-dimensional color object having a contoured surface onto a substrate includes printing color ink layers and structural ink layers. A color ink layer is printed onto the substrate. Structural ink layers are printed onto the color ink layer to build the three-dimensional shape of the object. The contoured surface is formed from varying the heights of pixel columns in the printing information. The heights of the pixel columns may be varied by printing different numbers of layers in adjacent columns or by printing the same number of layers in adjacent columns where some pixels in a column have different thicknesses than other pixels in the column.
