Preview

Instructs the scanner to perform a 75 dots per inch (dpi) resolution, 100% scale, in Line Art composition.

A preview is effected by the Threshold setting and the Graymap setting.  Typically, Preview is used to obtain a rough scan image to set scan areas prior to using Scan.

A preview scans the entire scanner glass, ignoring any scan areas set in the Scanner window.

This setting instruct the scanner how to determine whether a scanned pixel should be black or white.  The setting determines the density at which the scanner detects a block dot.  The Threshold setting affects line art composition scans, conversions of grayscale images to line art, previews and adaptive filtering.
