Table 8-10 Human Readable/Extended Bars TCI’s
The Text/Extended Bar TCI’s generate the human readable text and extended bars that are
aligned with the original bar code to create the complete bar code, see Figure 19.
Figure 8-13 UPC-A Text/Extended Bars
The TCI 32 text/extended symbol, shown in Figure 27, is positioned with the TCI 12 code so
that there is no space between the two. This creates one bar code. TCI’s (17, 22, 23, 32,
and 33) that add the extended bars should default the CGN parameter or enter a value of
“1”. The fields may then be multiplied using the CMX and CMY parameters to generate the
proper size to match the bar code that the human readable code is intended. The data
used to generate the human readable code should be the same data used to generate the
bar code.
TCI’s (3, 28, and 29) that only add the human readable portion may select any CGN for the
font size and multiply it normally. The main purpose of these codes is to add the
automatically calculated check digit character to the human readable code. The data used
to generate the human readable code should be the same data used to generate the bar
code.
The following is a sample format is used to illustrate the proper use of the human readable
code. This format contains the data used in Figure 27 and will print out two bar codes. The
first bar code is a complete version while the second bar code illustrates the text/extended
code before aligning to the original bar code.
