Note: With some media, the more dense (darker) colors may still show thin lines
when the correction factor is close to being correct (due to edge of swath banding);
in this case it may be wise to use the lighter colors to calibrate the correction factor.
Apply the Optimal MACF to the Current Media
The above procedure provides two values where neither white gaps nor dark lines
are present. The median value of this range is entered in the MACF field in the Roll
Media Manager. The given media profile (media thickness, tension, MACF, and
lamp power settings) can then be saved in the Roll Media Manager, and used
whenever that type of media is present.
Open the Roll Media Manager.
1.
Enter the media value in the MACF field.
2.
Click on "Create new media from current settings".

Note: You can either save the media with the same name or create a new name for
the media.
Result
