Transmission Mode

The mode where light is transmitted through a film

master symbol rather than reflected from a printed

symbol.

symbol below the normal specification. Truncation

decreases a symbol’s omni-directional readability

and should be avoided.

Valley

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

ley represents a bar. One or more valleys could

also be found within an element representing a re-

flectance 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

symbol.
