This Symbology is also known as GS1-128 Composite Barcode, GS1-128 CC-A (CCA), GS1-128 CC-B (CCB), GS1-128 CC-C (CCC), GS1-128 Composite A, GS1-128 Composite B, GS1-128 Composite C, GS1-128 2D Composite, GS1-128 Composite Component A, GS1-128 Composite Component B, GS1-128 Composite Component C

In Barcode Composite Symbology, the linear component encodes the item's primary identification while the adjacent 2D Composite Component (abbreviated as CC) encodes supplementary data, such as a batch number and expiration date. The Composite Symbol always includes a linear component so that the primary identification is readable by all scanning technologies. The Composite Symbol always includes a multi-row 2D Composite Component that can be read with linear- and area-CCD scanners, and with linear and rastering laser scanners. The 2D Composite Component is printed above the linear component and both are separated by a separator pattern.

GS1-128 Composite Barcode is an GS1-128 linear barcode linked to a 2D barcode called CC-A or CC-B or CC-C.

• GS1-128 (formerly UCC/EAN-128) Symbology is a subset of the more general Code 128 Symbology. By agreement among AIM, Inc., GS1 (EAN International and the UCC), use of the Function 1 Character (FNC1) in Code 128 Symbols in the first symbol character position following the Start Character has been reserved exclusively for the GS1 System. GS1-128 was developed to provide a worldwide format and standard for exchanging common data between companies. While other barcodes simply encode data with no respect for what the data represents, GS1-128 encodes data and encodes what that data represents.
• The 2D Composite Component that can be liked to GS1-128 can be one of the following depending on the amount of supplementary data to be encoded:
  • CC-A: it is a variant of MicroPDF417 barcode and the smallest of the 2D Composite Components which can encode up to 56 digits.
  • CC-B: it is a subset of MicroPDF417 barcode which can encode up to 338 digits. Encoding systems normally automatically select CC-B when the data to be encoded exceeds the capacity of CC-A.
  • CC-C: it is a PDF417 barcode which can encode up to 2361 digits(the greatest data capacity of the Composite Symbols). CC-C can be used as a 2D Composite Component within a GS1-128 Composite Symbol only.

In order to get GS1-128 CC-A, CC-B and CC-C Composite Barcode images, please follow these steps:

• Set the Symbology property to GS1128CCA or GS1128CCB or GS1128CCC
• Setting up dimensions and quiet zones:
  • Set the BarWidth and BarHeight properties per your requeriments (By default, values are expressed in Inches)
  • Set the BarRatio property to 3
• Set the Code property with the primary and secondary values separated by | char (See example below).
• Set the Text property to the Secondary Data which was encoded into the 2D Component

Code property = (01)03212345678906|1A1B2C3D4E5F6G7H8 (Primary Data = (01)03212345678906 and Secondary Data = 1A1B2C3D4E5F6G7H8), Symbology property = GS1128CCA, AddChecksum property = True will produce the following barcode image:
