LabelVision automatically adds a Mod 10 check digit to the end
of interleaved 2 of 5 bar codes when you enable the "Check Character"
option for this bar code. Also, LabelVision automatically puts a
Function 1 character at the beginning, and a and Mod 10 check digit
at the end, when you select the CODE 128 SCC-14/SSCC-18 symbology.
However, there are some applications where you may need more control
over the placement of these characters, including:
When you need both space and a Mod 10 check digit in the human
readable for your bar code. Although LabelVision puts the Mod 10
check digit at the end of the human readable generated when the
Human Readable option is checked in the "Select Bar Code" dialog
box, the human readable does not include the spaces required by
many compliance labeling specifications.
If you need to make a Code 128 bar code that is not exactly like
the Serial Container Code, or has a number of digits other than
19 (SSCC-18) or 15 (SCC-14).
The remainder of this document describes, in detail, how to create
a UCC code 128 Serial Shipping Container bar code and human readable
objects on your label.
Assume that we wish to have an application which outputs a typical
CODE 128 Shipping Container Code which consists of a "00" constant,
a 1 digit packaging type, a 7 digit manufacturer ID and a 9 digit
If the Total number of characters is exactly 19 or 15 digits, you
can use CODE 128 SCC-14/SSCC-18 symbology; For this symbology the
Function 1 and the MOD 10 check digit will be computed automatically
for you. If the number is other than 19 or 15 digits you must use
the Code 128 Subset C symbology, and embed the Function 1 and the
MOD 10 Check Digit yourself.
In the following example, we will use the Code 128 Subset C symbology
to create a bar code on a compliance label for Kmart.
Start the LabelVision designer. Click on the bar code tool, and
draw a bar code on your label. Press the "Bar Code Settings" button,
and choose the Code 128 Subset C symbology and turn off the
human readable. Next, click on Field Expression, and enter the following
This expression is broken down as follows:
This bar code has a function 1 character, 19 digits of data, followed
by a 1 digit MOD 10 checksum. Note that as in every code 128 bar
code a MOD 103 is appended to the end of the bar code.
Next, add a text field for the human readable. Choose an appropriate
font, and enter the following Field Expression:
Note that the parenthesis and spaces between fields are required
by Kmart (and other compliance labeling) specs. The resulting bar
code (when printed) appears below:
The label SSCC.LAB in the SAMPLES sub-directory of your installation
directory contains several examples of SSCC-18 & SCC-14 bar
