1. A method comprising the acts:
warping a 2D graphic artwork with a first warp, in anticipation of distortion when said artwork is later applied to a curvoid object, said warping the 2D graphic artwork yielding a warped 2D graphic artwork;
warping a 2D machine-readable code pattern with a second, different warp, in anticipation of distortion when said code pattern is later applied to said curvoid object, said warping the 2D machine-readable code pattern yielding a warped 2D machine-readable code pattern; and
applying both the 2D warped graphic artwork and the warped 2D machine-readable code pattern to said curvoid object;
wherein warping applied to the 2D graphic artwork is different than warping applied to the 2D machine readable code pattern.
