6. Take the set of printed charts and remove the first charts that are not marked with a number.
One sheet is printed on the front side, the other sheet is printed on the back side.

7. Measure the charts. (

on page 236)
8. Read the feedback information. (
Read media family calibration feedback
on page 227)
• When the differences with the previous media family calibration are negligible, you can
decide to reject the new calibration values.
• When calibration measurements seem to be inaccurate, calibration charts could have been
printed with artifacts or on the wrong media. Check the prints and the target media.
• When there are no visible artifacts and the chart media were correct, the manual chart
measurements were possibly executed with small inaccuracies. You are strongly advised
to redo the media family calibration.
• When the measurement accuracy results do not improve, there can be another problem.
The heatmap can indicate a possible problem, but cannot analyze the problem. Similar
patterns of reddish patches that appear after several similar calibrations can indicate that
there is a structural problem. Carefully check your job prints if there is a print quality
problem.
• When one or more primary colors or the paper white value deviate from the reference
values calibration charts could have been printed with artifacts or on the wrong media.
Check the prints and the job media.
9.
Finish the media family calibration when you accept the results. Close the calibration
procedure when you want to reject the calibration values.
10. Repeat the calibration procedure when the media family has more media print modes to
calibrate.
