DPI
Dots Per Inch. A standard unit of measurement for scanners and printers. Scanners are given a DPI rating even though they create pixels not dots. DPI is also a scanners' measure of its' enlargement capabilities. DPI is not a good measure of a scanners overall image quality.

Dynamic Range
An instruments range, such as a scanner, of measurable values. The range is from the lowest value it can detect to the highest value. A perfect dynamic range for a scanner is considered to be 4.0 or Dmin=0 and Dmax=4. The dynamic range of a scanner is most indicative of its' overall image quality with 3.0 being a minimum rating for prepress capable scanners.
