GS1-128, formerly known as UCC/EAN-128 Symbology, is a variant of the Code 128 Symbology.
The UCC EAN System was established by Uniform Code Council (UCC) in 1973.
In 1977, the European Article Numbering Association (EAN International) designed a compatible system for use in Europe.

The pattern of using FNC1 right after start character is reserved for GS1128.
According to the specification, a GS1128 symbol has the following characteristics:

Space is excluded from encodable charset.
The maximum data characters can be encoded is 48.
Including quiet zones, the maximum physical length is 165 mm (6.5 inch).
The minimum height of the symbol is 32 mm (1.25 inch).
The Human Readable Text of the data must be shown below the symbol. Start, stop, FNC1 character, and check digit are not shown.
Application Identifiers (AIs) define the interpretation of data.

GS1-128 (UCC/EAN-128) is flexible. It is used for the representation of Element Strings using EAN-UCC System Application Identifiers. It is not intended to be read on items passing through the Point-of-Sale.

The system provides a series of Application Identifiers (AIs) that define the interpretation of data.

Generate GS1128 Barcode in Crystal Reports

GS1128 is designed upon Code128. Therefore, GS1128 barcode is encoded by Code128 barcode font.

1. Open your crystal report. Right click Formula Fields, choose "New..." from the context menu.

Type in "GS1128" in the Name textbox, then click "Use Editor".

2. From Functions List ==> Additional Functions ==> COM and .NET UFLs (u212com.dll) ==> Visual Basic UFLs, double click to choose "BCSLinearGS1128" function as shown below.

3. Then type in the database field as parameter for GS1128 formula. And click "Save" button to save GS1128 formula field.

Please notice that FNC1 will be added for you automatically when necessary. When preceded by a variable-lengthed Application Identifier, the DLL will place a FNC1 before the new Application Identifier.

When you need to encode multiple AIs in one GS1-128 bar code, please put parentheses before and after each Application Identifier (AI).

Therefore, AI (02) and (10) will be input as shown below
(02)12345678901234(10)12345678901234567890
The first FNC1 will be output as "[C1".
Other FNC1 will be output as GS (ASCII 29).

4. Drag and drop the GS1128 formula field in your crystal report design view. You will see some strange characters in your report. Don't worry! You have NOT applied GS1128 barcode font yet.
