The image has a metallic hue (bronzing)
Bronzing describes an image that has a metallic hue when it is viewed from specific angles. Bronzing
occurs most commonly when you print pigmented inks on non-matte paper, such as photo paper. If you
are using standard print-quality options and the image contains the bronzing effect, move the slider to
Quality. See Select print quality on page 80 .
If you are experiencing bronzing when printing grayscale images on glossy paper, try using the Full Set
of Inks printing option. To do so from the Windows driver, click the Color tab and select Print In
Grayscale, and then select the Full Set of Inks option from the drop-down menu.
