1. A method for printing a white underbase and a highlight white onto a substrate in one pass, the method comprising:
processing, by a raster image processor, image data and generating from said image data any corresponding white underbase data, color data, and highlight white data;
for each pixel in the white underbase data:
determining whether a corresponding pixel exists in the highlight white data; and
in response to determining that the corresponding pixel exists in the highlight white data, increasing an ink percentage value of the underbase pixel to by a higher ink percentage value;
printing onto the substrate the white underbase data that includes at least one white underbase pixel at the higher ink percentage value; and
printing onto the substrate the color data.
