Grainy

In a “grainy” appearing image, the individual dots of ink are noticeable, instead of a photographic,
continuous tone image. This may occur if the image is being viewed at a closer distance than
recommended, given how the image was printed.

Print at a higher resolution (600x600 or 600x1200 dpi).

Print with 6 colors instead of 4 colors (if available).

Print in a higher quality mode (Production or High Quality).

Perform a bidirectional calibration (see

Auto calibrations on page 53

).

Perform a head height calibration (the head height may be too high). See Printer Settings > Head
Height off Media.

Note that sometimes changing one setting or condition to address one problem may at the same time
exacerbate a different problem. For example, printing with 4 colors may reduce ink load and saturation
and reduce banding, but may increase a grainy appearance in images. Experience will help you decide
which of several factors to adjust to improve overall image quality.

Not enough saturation or contrast

Use High Quality mode.

Start with a good image, and apply the correct ICC color profiles in the application program or RIP.
