An image processing apparatus includes a reception unit and a conversion unit. The reception unit receives as a designated color a color of an image desired to be seeable when irradiated with light at a specific wavelength. The conversion unit converts, when converting image data on an image to be printed into print data, a color value of the designated color received by the reception unit into a color value including a value for outputting a special color material that has absorption properties for the light at the specific wavelength.
