Transmission Mode
The mode where light is transmitted through a film master symbol rather than reflected
from a printed symbol.
Truncation

Truncation decreases a symbol’s omni-directional readability and should be avoided.
Valley

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
