Abstract:
1. An image processing apparatus comprising: a reception unit that receives color image data composed of process color image data, which are image data represented in process colors, and spot color image data, which are image data represented in spot colors that are different from the process colors; an intermediate data generation unit that generates intermediate data including color information indicating a color of each image data on the basis of the color image data received by the reception unit; an extraction unit that extracts spot color image data from the intermediate data generated by the intermediate data generation unit; a conversion unit that converts color information on the spot color image data extracted by the extraction unit into color information represented in the process colors; an addition unit that adds color transparency information indicating a proportion of a color to a color of image data in a background to the color information on the spot color image data converted by the conversion unit; a determination unit that determines whether or not the intermediate data generated by the intermediate data generation unit for each image data have background image data, which are other image data provided in the background to overlap the image data; and a drawing processing unit that performs a drawing process on the basis of the intermediate data, the color information on the spot color image data converted by the conversion unit, and the color transparency information added by the addition unit, wherein in the case where the determination unit determines that the intermediate data for spot color image data have background image data, the drawing processing unit performs a drawing process so as to add a color of the spot color image data and a color of the background image data of the spot color image data on the basis of the color transparency information added by the addition unit, the color information on the spot color image data converted by the conversion unit, and the color information on the background image data.
