Print data generating apparatus, image processing apparatus, and computer usable medium therefor

An image processing apparatus which processes image data, comprising:

• a conversion table storing system, which stores a white conversion table defining a white colorant level corresponding to color information of each of a plurality of pixels that configure the image data, the white colorant level indicating a level of white colorant to be used in the printing apparatus;
• a colorant data generating system, which generates white colorant data wherein color information of each of the plurality of pixels is converted into the white colorant level according to the white conversion table;
• and
• an image saving system, which applies an imaging process to the white colorant data and saves the processed data as white image data.

A computer usable medium comprising computer readable instructions for controlling a computer to generate print data which is used for printing in a printing apparatus based on image data by executing steps of:

• storing a white conversion table which defines a white colorant level corresponding to color information of each pixel in image data, the white colorant level indicating a level of white colorant to be used in the printing apparatus;
• generating white colorant data wherein color information of each pixel in the image data is converted into the white colorant level according to the white conversion table;
• and
• generating white print data to be used for printing with the white colorant in the printing apparatus based on the white colorant data.
