- The ACC is usually sufficient to adjust the color balance to get the best print output. You only need the printer gamma correction to fine-tune to meet user requirements.
 
Use SP modes if you want to modify the printer gamma curve created with ACC. You can adjust the gamma data for the following:
- Highlight
 - Middle
 - Shadow areas
 - IDmax.
 
The adjustable range is from 0 to 30 (31 steps).
