Abstract
A printing apparatus is adapted to receive print data specifying a color of an object to be printed with RGB values and specifying a type of the object as one of a text object, a graphic object and an image object. A print processor is operable to generate black image data from a set of the print data for one page, such that a black density value for one color of at least the text object is made greater than a black density value for the one color of the image object. A print engine is operable to perform monochrome printing with black toner in accordance with the black image data.
