8-15
Several Application Identifiers (00, 01, 22, and 8003) specify fields that will have a check
digit as part of their data. A character must be included in the check digit place (although it
need not be the correct check digit). This character is used as a placeholder and will not be
printed. The printer will calculate the correct check digit and replace the character already
there.
8.1.20 UCC/EAN Text Information, TCI 51
The TCI 51 generates the UCC/EAN information as text. This TCI uses the same criteria for
formatting as the TCI 50 bar code. The CGN selects the desired resident font that will be
used to generate this string. The printer will automatically surround each application
identifier with parentheses and add a space character in front of the data when using a TCI
of 51. Do not use the parentheses or spaces when entering the data for an application
identifier field.
8.1.21 RSS-14, TCI 35
RSS-14 Reduced Space Symbologies are the latest barcode types for space-constrained
identification from EAN International and the Uniform Code Council, Inc. (UCC). RSS
barcodes have been identified to solve problems in the grocery industry and in healthcare,
where items are too small to allow for older barcode symbologies.
All six different RSS-14 symbologies:
1) RSS-14
2) RSS-14 Truncated
3) RSS-14 Stacked
4) RSS-14 Stacked Omni-directional
5) RSS-14 Limited
6) RSS-14 Expanded.
8.1.21.1
RSS-14 Standard
RSS-14 is capable of encoding up to 20 trillion values. There are actually 15 characters
that make up the barcode, but only 13 data characters and 1 check are encoded. The first
character is a flag, which determines if there is a Composite 2D barcode associated with the
barcode. This is the first character encoded and it should not be included in the “Data To
Encode” field.
The next 14 characters are the 13 data characters plus an implied check digit. The check
digit is not actually encoded in the barcode, but should be included as part of the “Data To
Encode” field.
If less than 14 characters are entered in the “Data To Encode” field, zeroes are padded to
the front after the linkage flag. Non-numeric characters are stripped from the “Data To
Encode” field.
