Meaning of the service color balance target gamma data and
the purpose of registration
This procedure must be executed only when the color balance is
customized with SIM 67-25.
If the color balance is not customized, this procedure is not
required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 67-25 according to the user's request, use SIM 67-27

CAUTION: In this case, be sure to use A4 or 11" x 8.5" paper for
printing the adjustment pattern by SIM 67-25.
By this procedure, the service color balance target is revised.
It is recommended to keep the printed adjustment pattern created
with SIM 67-25. This adjustment pattern can be used to register the
same color balance target to another machine.
It is also useful to register the service color balance target data. Do
not fold it and keep it under the circumstances which protect it from
discoloration and dirt.
The service color balance target data is basically registered imme-
diately after the color balance adjustment (Manual) with SIM 67-25.

If a considerable time has passed after completion of the color bal-
ance adjustment (Manual) with SIM 67-25, the color balance of the
adjustment pattern at the time of adjustment differs from the color
balance of the adjustment pattern printed after a considerable time.
Never use such a pattern for the adjustment.
The correctness of the service color balance target data can be
judged as follows.
When result of the color valance adjustment (Auto) with selecting
the service color balance target in SIM 67-24 is unsatisfactory or
abnormal.
In that case, the registered service target data for the color balance
adjustment (Auto) may be improper.
This may be caused when an improper or abnormal color balance
adjustment pattern was used to register the service color balance
target data for the color balance adjustment with SIM 67-27.
The color balance adjustment pattern used in registration was
made and printed by the color balance adjustment (Manual) with
SIM 67-25. This procedure may have been executed erroneously.
