Interleaved 2 Of 5
(Code I 2/5)
The name Interleaved 2 of 5 is derived from the
method used to encode two characters. In the sym
-
bol, two characters are paired, using bars to repre
-
sent the first character and the interleaved spaces to
represent the second character. Each character has
two sets, one bars and one spaces. Each consisting
of two wide elements and three narrow elements.
Bars and spaces are wide or narrow and the wide
bars are set by the ratio.
Interleaved Two of Five code support the numeric
characters:
0123456789
The printer will automatically add a leading zero
(‘0’) to the odd number of bar code data characters.
The supported ratio of narrow bar to wide bar
widths are: 2:1, 2:5 (2.5:1), and 3:1.
The equation to calculate the Code 2/5 bar code
length is:
L=[©(2R+3))+6+R]X
L = Length of bar code
C = Number of characters
R = Ratio of wide to narrow bars (5:2=2.5)
X = Number of Dots times 0.0033 inches per dot (0.08847
mm per dot)
The minimum recommended height of a Code 2/5
bar code is 0.25 inches (6.35 mm) or 75 dots.
Ideally the bar code height should be 15% of the bar
code length. The recommend “Quite Zone” is
0.25" (6.35mm or 75 dots) or 10 times X if
larger.
