<p>A method of printing on a print medium (11) with an ink jet printer (13) uses a first color ink, a second color ink and a black ink. An image area on the print medium has a plurality of pixel locations. Print image data (24) indicate on of a presence and on absence of the first color ink, the second color ink and the black ink at the plurality of pixel locations. A subset of the print image data is defined. A determination is made as to whether the subset of print image data indicates: (1) a presence of the first color ink and/or the second color ink within the subset and a presence of the black ink within the subset; (2) a presence of each of the first color ink and the second color ink within the subset at a same corresponding pixel location; and/or (3) a presence of the first color ink and/or the second color ink within the subset at a number of corresponding pixel locations exceeding a threshold value.</p> |
