[Rotate/Skew]
Overview
Perform adjustments when the entire image is rotated clockwise or counterclockwise or a diagonal skew is detected.
[Rotate/Skew] is automatically set to the compensation value by making the following adjustments.
[Chart Adjustment] of [Rotate/Skew]
[Chart Adjustment] of [Back]
[Scan Meas.] adjustment
The compensation value can be adjusted manually.
[Rotate/Skew] adjustment example
[Rotate]: When the image on the front side is skewed clockwise, press [Front] - [Rotate], and enter the positive value. The image on the front side rotates counterclockwise.
[Skew]: If a skew slanting toward the upper right is detected on the front side of the image, press [Front] - [Skew], and enter the negative value. The skew reduces, and the image approaches a normal form.
NOTICE
The following setting is required to use this function.
- Set [Both Sides Rotate/Skew] in [Common Setting] to [Enable].
Tips
- When a compensation value has been entered on the [Rotate/Skew] screen, even if [Both Sides Rotate/Skew] is set to [Disable], the compensation value information remains. If [Both Sides Rotate/Skew] is set to [Enable], the chart adjustment can be made with the same compensation value.
