See Global Threshold)

Transmission Mode

The mode where light is transmitted through a film

master symbol rather than reflected from a printed

symbol.

Truncation

Decreasing the length of the bars in a bar code sym-

bol below the normal specification. Truncation de-

creases a symbol’s omni-directional readability and

should be avoided.

Valley

The graphical pattern on a scan reflectance profile

which looks like a “U” or “V.” Within a profile a valley

represents a bar. One or more valleys could also be

found within an element representing a reflectance

change within an element.

Vertical Redundancy

The availability of more than one scan path through a

bar code symbol.

Visual Measurement

Measurements obtained by using human vision in the

determination of characteristics of the bar code sym-

bol.
