Abstract:
A print data generating apparatus to generate print data, which is to be used in a printing apparatus to form an image in a plurality of colorants, based on originally inputted image data representing the image, is provided. The print data generating apparatus includes a black enabled image data converter unit to convert the inputted image data into black enabled image data, which indicates scale values of a plurality of colors including a black color to be used in the image, a white scale value calculator unit to obtain scale values of a white color to be used in the image to be formed. The white scale value calculator unit calculates the scale values of the white color by inverting the scale values of the black color obtained in the conversion by the black enabled image data converter unit.
