- Entering correction values after checking gamma and gain settings
Calculate each correction value based on the readings on the sample gauge taken at step 3).
*The gamma scale has values ranging from -0.30 (0.7) to +0.30 (1.30) to show the deviation of a reading
from the gamma reference value 1.00 that may need correcting.
*The gain scale has values ranging from -12% to +12% to show the deviation of a reading from the gain
reference value 0% that may need correcting.
4) Gamma
correction
steps
“Example: gain and gamma readings of -8% and -0.15 for cyan”
Referring to Table A, you lean that the gamma adjustment value is +0.10 for the gain reading of -8%. Add
the gamma reference value 1.00 and the gamma adjustment value to the gamma reading as calculated
below.
*gamma reference value 1.00 + gamma reading -0.15 + gamma adjustment value +0.10
= gamma correction value +0.95.
-Keep clicking the button “
▲
” or “
▼
” for the cyan gamma setting on
the color correction dialog
until the
gamma value “0.95” appears, as shown below.
*You can set the gamma value to +0.05 to +3.00.
- Press
Apply
after you have completed the entry.
* To cancel the setting, press
Cancel
.
Next, enter a gain correction value.
* If you want to quit the color correction setting without correcting a gain setting, follow the steps 1) to 3) to
print cyan after you have pressed
Apply
above.
- Take out the printed disc from the tray and check if the gamma and gain readings on the sample gauge
fall within the acceptable ranges below.
Color correction is not required if the gamma and gain readings respectively fall within the ranges of
-0.05 to +0.05 and -2% to +2%.
(If desired, correct the settings so that the gamma and gain readings can be closer to the ideal values of
0.00 and 0% respectively on the sample gauge.)
If no further correction is needed, the color correction to cyan is completed.
*
If you want to correct colors other than cyan now, go back to step 1) and select a color you want to print
on
the color correction dialog
.
