【Effect of the invention】
As described above, according to the inventions of claim 1 and claims 11 to 18 , color conversion is possible such that the highlight part is also a natural color tone for all color tones for all media. A medium storing color conversion table data, a medium storing a color conversion program, a color conversion apparatus, a color conversion method, a color conversion program, and a color conversion table can be provided.
Further, according to the invention of the second aspect, printing can be performed without exposing the ground color of the print medium used in the second image device.
Furthermore, according to the third aspect of the present invention, color conversion can be performed such that monochrome images including low saturation colors can be printed naturally on all media.
According to the fourth aspect of the present invention, the second image device can output an image with a natural color tone without affecting the color tone of the image due to the ground color of the medium.
Furthermore, according to the invention of claim 5, the tone jump does not occur due to the change of the color in the image, and the natural color tone can be obtained.
