9 or : Optional parameter to select a variable ratio bar
code. Enter the number 9 to select a variable ratio
bar code. This feature overrides the default EAN 13
ratio 1:1:2:2:3:3:4:4.
If the : parameter is specified, the ratios are
represented in printer dots instead of IGP dots
(60 x 72 dpi).
type Represents the bar code type. Enter T for standard
EAN 13; enter m for EAN 13 plus a 2-digit add-on
data field; enter n for EAN 13 plus a 5-digit add-on
data field.
ratio Optional parameter (used in conjunction with 9
above) representing the ratios for variable ratio bar
codes. Default ratios are overridden by the variable
ratio feature. However, unique variable ratios for
EAN 13 bar codes easily generate large, out-of-
spec bar codes. Ratio data must be hexadecimal
numbers from 0 through 9 or A through F; the Code
V automatically checks the input for validity. If an
invalid character is found in the ratio, an error
message is generated.
EAN 13 bar codes use eight-digit ratios. The ratios
are interpreted from left to right, measuring the size
of each bar or space, in dot width, in the following
pattern:
1 module wide bar : 1 module wide space :
2 module wide bar : 2 module wide space : 3
module wide bar : 3 module wide space : 4 module
wide bar : 4 module wide space.
The Code V automatically checks ratio data for validity only within the
allowable hexadecimal range. The Code V does not verify that ratio data
creates acceptable bar/space element relationships for bar code readability.
When designing unique ratio data, carefully plot bar/space ratios to conform
to readable bar codes.
data The bar code data. EAN 13 bar codes encode
exactly 12 digits. The first character input is
interpreted as the number system character. (A bar
code character is not produced for the number
system character.) The next six characters are the
left side (the upper side on vertically oriented
symbols). The final five characters are the right side
(or the lower side on vertically oriented symbols). A
thirteenth character is an automatic check digit
which is computed and printed in the last character
position in the right data field. If the 2- or 5-digit
add-on data field is used, include this data at the
end of the data field. The characters available for
the data field are 0 through 9 (hex 30 through 39,
respectively).
