Scan Quality; Gray Scan Ccd Filter - Microtek ScanMaker IIG User Manual

Scan Quality

This option allows you to select the quality of your scans.
• Choose Draft if you're outputting images as drafts. This
option speeds up the scanning process, but the image may
be a little coarse (compared to the Final option).
• Choose Medium if you're outputting images as medium
result. This option outputs general image quality -- not as
nice as Final, yet better than Draft.
• Choose Final if you wish to have a scanned image of
better quality. This option, however, is slower than Draft.

Gray Scan CCD Filter

This option allows you to select a particular color channel
when scanning grayscale images and is useful for obtaining
certain effects.
When scanning grayscale images, one of the color channels of
the CCD can be used for scanning; this could be the red, green,
or blue color channel.
