Three-dimensional shape color adjustment method, three-dimensional object shaping method, and three-dimensional shape color adjustment apparatus

A three-dimensional model color adjustment apparatus comprising:

• a data conversion unit which converts three-dimensional data representing a three-dimensional object having colored layers formed on a surface thereof into two-dimensional data;
• a two-dimensional color patch data creating unit which creates, as two-dimensional color patch data, a plurality of two-dimensional images in which at least one kind of parameter of a plurality of kinds of parameters related to a color of each layer of the colored layers in the converted two-dimensional data is set at a plurality of different levels;
• a three-dimensional color patch data creating unit which applies thickness information about thicknesses of the colored layers depending on the number of layers of the colored layers to the two-dimensional color patch data to create three-dimensional color patch data;
• and
• a color patch layering unit which layers three-dimensional color patches depending on the thickness according to the three-dimensional color patch data, wherein
• the colored layers are formed with a plurality of inks by an inkjet method, and
• the three-dimensional model color adjustment apparatus further comprises a color density adjusting unit which adjusts a color density parameter of each of the plurality of inks to create the two-dimensional color patch data.
