3.13.2 PRINTER GAMMA CORRECTION
NOTE:
Normally, the ACC is enough to adjust the color balance to achieve the
optimum print output. The printer gamma correction is only required for
fine-tuning to meet user requirements.
The printer gamma curve created during ACC can be modified using SP modes.
The SP value will be applied to the gamma curve created during ACC.
The gamma data for highlight, middle, shadow areas, and IDmax can be adjusted.
The adjustable range is from 0 to 30 (31 steps).
Copy Mode
