Inter-character Gap
In discrete barcodes, the space that separates two
adjacent characters. When present, inter-character
gaps are considered spaces (elements) for purposes
of edge determination and reflectance parameter
grades.
Interleaved
A bar code in which characters are paired together
using bars to represent the first character and spaces
to represent the second.
ISO
International Organization for Standardization,
organization that maintains the standards related to
bar codes and bar code verifiers.
Ladder Code
A bar code or symbol printed vertically with the
individual bars looking like the rungs of a ladder.
Laminate
See Over-laminate
Laser Scanner
A bar code reading device that uses a low energy
laser light source for illumination.
Magnification Factor
The size of a printed bar code compared to a
standard (nominal) size.
Maximum Element Reflectance Non-uniformity (ERN
max)
The largest element reflectance non-uniformity in a
scan reflectance profile.
