Adjustment procedure 2
(visual inspection)
1. First adjust [MIN] tone [G:].
2. Select [No.2] [G:].
If the background is [G] monochrome, press the
[ENTER] key on the Remote control transmitter to
change to solid white.
3. View measurement point [No.2] and [No.3].
Lower the [G] colour intensity only of the colour
point whose [G] colour is more intense than
measurement point [No.1].
4. View measurement point [No.10] and [No.11].
Lower the [G] colour intensity only of the colour
point whose [G] colour is more intense than
measurement point [No.1], and raise the intensity
of the point whose colour intensity is lower than
measurement point [No.1].
5. Now adjust the [MIN] tone for colours [R] and [B].

6. View measurement points [No.2], [No.3], [No.10]
and [No.11]. Adjust the [R] and [B] of each
measurement point so that they have the same
color as measurement point [No.1].
Adjustment technique:
First, adjust [B:] of the point whose colour is to be
adjusted so that it approximates that of [No.1]. If
[R:] is low at this time, the image will have cyan
cast, in which case [R:] is increased. On the other
hand, if [R:] is excessive, the image will have a
magenta cast, in which case [R:] is decreased.
Overall, a cyan cast makes it easy to see colour
shading.
7. Next, view measurement points [No.4], [No.5],
[No.12], [No.13] and make similar adjustments.
8. Then adjust measurement points [No.6], [No.7], [No.8],
[No.9], [No.14], [No.15], [No.16] and [No.17].
This completes the [MIN] tone adjustments.
9. Make similar another three tones as described in
steps 1 to 8 above.
