Patent ID: 8446633

Claim:
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 colors of colorants including a white colorant, based on originally inputted image data representing the image, comprising: a maximum density setting unit, through which a maximum allowable density of the white colorant to be used to form the image is designated; an image storing unit to store the originally inputted image data; a data convertor unit to convert the originally inputted image data into a colorant-enabled data, which is information concerning pixels composing the image in scale values of the plurality of colors; and a density-adjusted data generating unit to generate white density-adjusted data, in which the scale values of the pixels in the colorant-enabled data are adjusted according to the maximum allowable density of the white colorant designated through the maximum density setting unit, wherein the density-adjusted data generating unit adjusts the scale values of white in the pixels in the colorant-enabled data to be lower than or equal to scale values corresponding to the maximum allowable density by obtaining a ratio of the maximum allowable density with respect to a predetermined maximum capable density, which is a maximum density of the white colorant to be used to form the pixels in the printing apparatus, and multiplying the scale values of white in the pixels by the obtained ratio.
