o
Do the RIP or application print settings
differ from the actual print conditions?
Printing cannot be performed correctly if the paper
type or black ink type differ from the RIP or
application settings. Check the the paper type
loaded in the printer and the black ink type settings
are correct.
o
Was the color measurement chart printed
with clogged nozzles?
Check that there is no visible banding (horizontal
lines at regular intervals) in the color measurement
chart. If a color measurement chart is printed with
clogged nozzles, the correct color measurement
result cannot be acquired. If there are clogged
nozzles, perform head cleaning, and then print the
color measurement chart again.

measurement chart, or does ink peel off?
If there are stains or scratches on the color
measurement chart, or if ink peels off, the correct
color measurement result cannot be acquired.
Reprint the color measurement chart.

Is the color measurement chart sufficiently
dry?

time is not increased beyond the standard time, ink
will not be dried sufficiently. Set a longer drying
time in the RIP or application you are using. See the
manual supplied with the RIP or application for
more information in setting the drying time. See the
manual supplied with the paper for more
information on the drying condition.
