Abstract:
A method is disclosed. The method includes receiving color data for an object to be printed and performing post color processing for each pixel in the object if the object is a graphics/text object, while no processing is performed if the object is an image object. Post color processing is performed by determining if a pixel is black or gray and converting the pixel to K only black color if the pixel is black or gray.
