magazines.
This item is grayed out when [Film] has been selected as the Image Source
or when the resolution is more than 600 dpi, or when the Color Mode is
Black and White or Text Enhanced.
This function is the same as the Descreen function in the Advanced mode.

Source.

image but the slower the scanning speed. Make sure you select a
setting based on the capability of your output device.

an image larger than 21,000 x 30,000 pixels cannot be cropped or
