US Patent 10071527 Colour 3-dimensional printing with 3D gamut mapping

Provided is a Layered Object Manufacturing, LOM, system configured to form a colored three-dimensional (3D) object, the system comprising: a 3D object gamut mapping module configured to define a 3D object formed from a plurality of surfaces and provide a printing regime consistent with the defined 3D object, wherein the 3D object gamut mapping module is configured to analyze the orientation of a surface of each of a plurality of media layers to be printed in order to adaptively modify the color printed to that layer; and a printer configured to color print at least a portion of a first surface of each of the plurality of layers in accordance with the printing regime. Also provided is a color 3D object media layer printing module for providing a print-through region in a 3D object media layer. Also provided is a 3D object gamut mapping method, and ink for use in a Layer Object Manufacturing (LOM) system including the printing module.
