5.6.1.3.1.8 Codabar / Codabar 18 - Additional test criteria
The
Codabar is a very old code symbology that is used in the
pharmaceutical industry and in the photo lab sector. It is no longer
current and should not be used with new applications.
The Codabar can use a check digit, although this is not essential.
The check digit is formed per Modulo 11 or Modulo 16 and is
checked by the REA ScanCheck 3n if the check box is activated.
The ANSI check box permits size ratios between the narrow and
wide bars of between 1:2.5 and 1: 3.0, if the module width is below
0.5 mm. The ISO standard always permits ratios between the
narrow and wide bars of 1:2 to 1:3 without limitations as with ANSI.
Codabar 18 (optional symbologies) is a predecessor version of the
2 bar wide Codabar code (Codabar Monarch) and has 18 different element widths. The same
additional test criteria apply here as with the Codabar.
5.6.1.3.1.9 2 of 5 Interleaved / ITF-14 Code - Additional test
criteria
The
2/5 Interleaved Code was developed to obtain codes with a
higher coding density, i.e. many characters in a small space.
Activation of the check box “Check digit: Modulo 10” enables testing
of the check digit per Modulo10 or for the consignment notes of
Deutsche Post AG.
With selection of the ‘
ANSI
’ box, ratio checking switches from the
ISO standard to ANSI standard and back. With ANSI, size ratios are
permitted between the narrow and wide bars of between 1:2.5 and
1: 3.0, if the module width is below 0.5 mm.
The ISO standard always permits ratios of 1:2 to 1:3 without limitations as with ANSI.
A bar code reader cannot automatically distinguish between these two code types. For this reason,
only one or the other code type can be activated in the pre-settings (i.e. either 2/5i or ITF-14).
The
ITF-14 Code is a special form of the 2/5 Interleaved Code with a few additional limitations and
specifications and GS1 data structure.
This code can only be selected if the 2/5 Int Code is not activated.
In the GS1 General Specifications, the code sizes are specified depending on the application area.
These are listed in so-called symbol specification tables (SST). By selecting the menu item
“Change GS1 module size”, the size table can be set according to the application area, as
described with EAN-13 in chapter 5.6.1.3.1.2.
