option is especially useful to check the quality of the color rendering and the
color fastness.

Problem
Drop-out
Banding
Description
Problems with the noz-
zles can cause drop-out.
Banding means that a
print contains regular
horizontal stripes.
These stripes can ap-
pear as light or dark
bands. Problems with
the nozzles can cause
banding. The tone scale
area check is printed in
the 'Presentation' mode
and must not contain
banding.
