► The field separator FNC1 (encoded by the sequence „\F“) has to be used because the batch
number is a variable length data field and has only 8 characters (and not the maximum of 20
characters).
5.2.3 EAN-128 with embedded Check Digit
Sometimes it is required to calculate a check digit only for a partial content of a barcode. A good
example is the AI 01 (GTIN) in combination with other data fields within an EAN-128 symbol.
Description Value
AI for GTIN 01
AI for Date 11
GTIN without check digit 1234567890123
Production Date 060606
In our example, the GTIN contains no check digit (e.g. when created based on the EAN-13
number). The check digit has to be generated only for the first 13 digits of the supplied data and not
for the full data content.
Since TBarCode Version 7+ you can use the format property to solve this problem:
Description Value
Format property: 01#############^11######
Input Data (Text property): 1234567890123060606
Check Digit Method: EAN-14 (Mod-10)
Calculated Check Digit: CD = Mod-10 of (1234567890123) = 1
Result: 01 + 1234567890123 + CD + 11 + 060606
Data used for encoding: 011234567890123 1 11060606
5.3 GS1 DataBar Expanded / GS1 DataBar Expanded Stacked
The mentioned symbologies use an internal data compression algorithm for specific Application
Identifiers. Compression means that the barcode can encode more data or can be made smaller.
This optimization takes effect automatically if the AIs are applied in the following predefined order.
5.3.1 AIs with a Fixed Length
5.3.1.1 AI(01) and Weight
AI (01) must begin with an indicator digit of 9 for variable units
Combinations Description Max. Weight
AI (01) + AI (3103) Weight in kg with 3 decimal places (n,nnn kg) 32,767
AI (01) + AI (3202) Weight in pound with 2 decimal places (n,nn lbs) 999,99
AI (01) + AI (3203) Weight in pound with 3 decimal places (n,nnn lbs) 22,767
