Choosing Twain; Control Panel & Scan Mode - Plustek V1.4 User Manual

The TWAIN interface allows you to make important
adjustments before scanning. For example, you can scan in
different modes: Color, B/W or Grayscale; increase or decrease
the resolution (dots per inch of an image), and adjust the brightness
and/or contrast. The Prescan option allows you to adjust the
margins of a document by increasing or decreasing the frame
located inside the Prescan window. The TWAIN interface also
provides you with statistics: such as how big an image will be after
you scan it (in megabytes), the scanning area and position of the
margins.
