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
).
●
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.
