Adjustment procedure 1
(When a color differential meter is used)
1. First adjust the -MID-1- tone, from G color.
2. Select G of point No.2 and change the
EDFNJURXQGWRVROLG*PRQRFKURPH
3. Measure the illumination at points No. 2, 3, 10
and 11.
The values should be:
No.2 = Y2 [lx], No.10 = Y10 [lx]
No.3 = Y3 [lx], No.11 = Y11 [lx]
4. Points No.2 and No.3 have the average of Y2
and Y3.
Y2 = ( Y2 + Y3 ) / 2 ± 3 [%]
Y3 = ( Y2 + Y3 ) / 2 ± 3 [%]
5. Points No.10 and No.11 have the average of Y10
and Y11.
Y10 = ( Y10 + Y11 ) / 2 ± 3 [%]
Y11 = ( Y10 + Y11 ) / 2 ± 3 [%]
6. Then adjust R and B color of the -MID-1- tone.

7. Measure the color coordinates of point No.1 and

front panel. The measurement shown after this
displays the deviation from point No.1.
8. Measure the color coordinates at point No.2 and
adjust R and B color of point No.2 so that the
coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.005 (as target)
x = x1 ± 0.010 , y = y1 ± 0.015
9. Measure and adjust their color coordinates of
points No.3 to 17 in the same way starting in
order from the small number points.
This completes adjustments required for -MID-1-
tone.
NOTE: Since excessive correction may lead
to a correction data overview during internal
calculations, use the following values for
reference.
No.2 to 5: ± 40 or less
No.6 to 9: ± 50 or less
No.10 to 13: ± 70 or less
No.14 to 17: ± 120 or less
10. Next, adjust the other tones in order of -MIN-,
-MID-3-, -MID-2-, -MID-5-, -MID-4-, -MAX- and
-MID-6-.
11. Adjust each tone as follows, from G color.
-MIN- tone : one and a half of -MID-1- tone
-MID-3- tone : 0 (no adjustment)
-MID-2- tone : a half of -MID-1- tone
-MID-5- tone : 0 (no adjustment)
-MID-4- tone : average of -MID-3- and -MID-5-
tones
-MAX- tone : 0 (no adjustment)
-MID-6- tone : average of -MID-5- and -MAX-
tones
12. Select R or B of point No.2 at -MIN- tone and
FKDQJHWKHEDFNJURXQGWRVROLG:PRQRFKURPH

x1, y = y1.
14. Now measure the color coordinates at point
No.2 and adjust R and B color of point No.2 so
that the coordinates are as follows.
x = x1 ± 0.010 , y = y1 ± 0.020 (Target)
x = x1 ± 0.040 , y = y1 ± 0.080
15. Similarly, measure and adjust their color
coordinates of points No.3 to 17 starting in order
from the small number points.

Adjust them in the same way as the -MIN- tone
adjustments in the step 12 to 15 so that the
coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.005
17. Finally, set the values of the -MID-2-, -MID-4-
and -MID-6- tones as follows using the values
already set.
-MID-2- tone : average of -MID-1- and -MID-3-
tones
-MID-4- tone : average of -MID-3- and -MID-5-
tones
-MID-6- tone : average of -MID-5- and -MAX-

(visual inspection)
1. First adjust G color of the -MIN- tone.
2. Select G of point No.2 and change the
EDFNJURXQGWRVROLG:PRQRFKURPH
3. View point No.2 and 3. Lower the G color
intensity only of the color point whose G color is
more intense than point No.1.
NOTE: When adjusting a point, it affects around
the point as the diagrams.
4. View point No.10 and 11. Lower the G color
intensity only of the color point whose G color
is more intense than point No.1, and raise the
intensity of the point whose color intensity is lower
than point No.1.
5. Now adjust R and B colors of the MIN tone.
6. View points No.2, 3, 10 and 11. Adjust R and B
color of each point so that they have the same
color as point No.1.
Adjustment technique: First, adjust B color of
the point whose color is to be adjusted so that it
approximates that of point No.1. If R color is low at
this time, the image will have cyanish cast, in which
case increase R color. On the other hand, if R color
is excessive, the image will have a reddish cast, in
which case decrease R color. Overall, a cyanish
