GS1-128 (formerly UCC/EAN-128) CC-A, CC-B and
CC-C Composite Barcodes
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

GS1-128 Composite Component C
Overview
 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.
How to create GS1-128 CC-A, CC-B and CC-C Composite
Barcodes using BarcodeItem
Note: Please refer to the Class
Reference documentation for more information about the properties and methods
stated in this document.
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
