1. A method of operating a three-dimensional object printer comprising:

  • generating with a controller a first tone reproduction curve (TRC) having a first plurality of entries with a first precision, the first plurality of entries being generated with reference to a second plurality of entries having a second precision, the second plurality of entries being modified by a first value generated within a predetermined range prior to being used to generate the first plurality of entries, the second precision being greater than the first precision;

    generating with the controller a second TRC having a third plurality of entries with the first precision, the third plurality of entries being generated with reference to the second plurality of entries being modified by a second value generated within the predetermined range prior to being used to generate the third plurality of entries, the second value being different than the first value;

    receiving with the controller input contone image data corresponding to an image to be printed by the printer;

    generating with the controller first contone image data for a first plane of a multi-layer printed image with reference to the input contone image data and the first TRC;

    generating with the controller first halftone image data with reference to the first contone image data and a predetermined halftone process;

    operating with the controller a plurality of inkjets to form a first layer of the multi-layer printed image on a surface of a three-dimensional printed object with reference to the first halftone image data;

    generating with the controller second contone image data for a second plane of the three-dimensional printed image with reference to the input contone image data and the second TRC;

    generating with the controller second halftone image data with reference to the second contone image data and the predetermined halftone process, the second halftone image data being different than the first halftone image data; and

    operating with the controller the plurality of inkjets to form a second layer of the multi-layer printed image on the first layer with reference to the second halftone image data.
