Shaping device and shaping method utilizing color conversion process and color adjustment parameters

A shaping method for shaping a shaped object that is stereoscopic in which at least a part is colored, the shaping method comprising:

• using a head portion that ejects materials of a plurality of colors different from each other as a material of the shaped object;
• controlling an operation of the head portion based on an ejecting position specifying data indicating a position to eject the material of each color, the ejecting position specifying data being data in which a color with respect to at least a part of the shaped object is expressed in a material color space which is a color space corresponding to the color of the material used to color the shaped object;
• generating, in the control of the operation of the head portion, the ejecting position specifying data based on an input data input as data indicating the shaped object, the input data being data in which a color of at least a part of the shaped object is expressed in an input color space which is a color space different from the material color space;
• and
• performing, in a process of generating the ejecting position specifying data, a color conversion process of converting a color using at least of:
• a profile that associates the color in the input color space with the color in the material color space, and
• a color adjustment parameter which is a parameter used for adjustment performed for color conversion performed using the profile,
• wherein a color adjustment is performed based on the color adjustment parameter, the color adjustment is a color density conversion process for converting an input value of a color density before adjustment to an output value of a color density after adjustment according to a color density curve, where a horizontal axis of the color density curve represents the input value and a vertical axis of the color density curve represents the output value,
• wherein the color adjustment parameter specifies the color density curve that is set for each of the plurality of colors, and
• in the color conversion process, the controller is configured to change the color adjustment parameter to use in accordance with a thickness of the colored region in a normal direction of the shaped object, and the normal direction is a direction perpendicular to a surface of the shaped object;
• wherein the colored region having the thickness in which a plurality of layers of the material are layered, and
• in a place where a light reflecting region is provided behind the colored region when viewed from the normal direction, in response to make a color of the colored region seen from the normal direction with a color density of 100%, each layer of the material has a color with a color density of 100% divided by a number of the plurality of layers,
• as the color density of each layer of the material is increased, the number of the plurality of layers is decreased, so that the thickness of the colored region is thinner;
• as the color density of each layer of the material is decreased, the number of the plurality of layers is increased, so that the thickness of the colored region is thicker.
