SYSTEM AND METHOD FOR DECREASING TIME FOR PRINTING LAYERS IN THREE-DIMENSIONAL OBJECTS AND FOR ENHANCING COLOR FIDELITY AT THE SURFACE OF THREE-DIMENSIONAL OBJECTS
A three-dimensional object printer has a controller that operates pluralities of ejectors ejecting drops of different materials having different colors, at least one color of which is white, to produce objects with different levels of color saturation. The controller operates the pluralities of ejec...

| description | A three-dimensional object printer has a controller that operates pluralities of ejectors ejecting drops of different materials having different colors, at least one color of which is white, to produce objects with different levels of color saturation. The controller operates the pluralities of ejectors with reference to a function of a sum of an average number of drops per voxel in each layer, a target value of an average number of drops per voxel of colorants other than white in each layer, and a distance from a closest surface of the object for each material ejected by the ejectors. At a predetermined distance from a closest surface and greater, the controller operates the pluralities of ejectors to form voxels in layers of the object with only clear and white drops. At distances less than the predetermined distance, the number of clear drops increases and the number of white drops decreases. |
