UPC Bar Codes
-
Version
4.0
The Universal Product Code has been used in the North
American retail industry since 1973. There are two
different versions of UPC bar codes, UPC-A and UPC-E.
The UPC-A bar code is 12 digits long, including its
checksum. UPC-E bar codes are special shortened
versions of UPC-A bar codes and are 6 digits long.
Both UPC-A and UPC-E bar codes may have optional 2 or
5 digit supplemental codes appended to them.
Our scalable TrueType and PostScript bar code fonts
comes in five different aspect ratios, so you can vary
the height and width of the bars independent of each
other. This lets you print bar codes with the same
height, but different horizontal print densities. The
online manual comes in Rich Text format. Just print a
copy of the manual to see how to use these fonts to
print bar codes.
UPC bar codes encode fixed length numeric data. A
checksum is required, and checksum calculation is
complex. VBA functions for Access and Excel make using
our fonts in those programs a breeze. Our bar code set
includes BARUPC.EXE a utility, which builds bar code
strings and generates checksums for you and Word label
templates. The BarUPC program can export bar codes as
bmp, gif, jpg, or png graphic files.
