When you print a black-and-white image in color, black areas may be printed using CMY+K inks in some cases. To print black color more clearly, select black-and-white mode for printing black-and-white images.
If black-and-white printing is specified in the application, make sure that you select "Black & White" in "81. Color Mode". If you select "Color", black areas may be printed using CMY+K inks in some cases.
