RSS Composite Symbology Barcode

Bar code activeX software for printing bar codes without special bar code printers or barcode fonts. The EAN UCC Composite Symbology is a combination of a linear barcode component or RSS bar codes and a special 2D symbol Composite Component (CC) printed on top. The linear component or RSS (e.g. RSS-14) encodes the itemís primary identification. The adjacent 2D Composite Component (CC) encodes supplementary data, such as a batch number and expiration date.

The linear bar code component might be a:

  • EAN/UPC symbology (EAN-13, EAN-8, UPC-A, or UPC-E),
  • a member of RSS-Reduced Space Symbology family (e.g. RSS-14),
  • or an UCC/EAN-128


    The linear component determines the name of the Composite symbol, such as an EAN-13 Composite symbol, or a UCC/EAN-128 Composite symbol.

    Composite symbols are designed to be scanned with hand-held laser, linear CCD, or 2D imaging scanners.


    3 Versions of 2D CC-Composite Component are available

  • CC-A

  • CC-A is a variant of MicroPDF417 Symbol with a unique combination of row address patterns (RAP)l. It is the smallest variant of the 2-dimensional composite component. Up to 56 digits of alphanumeric data can be coded with 3 to 12 rows and 4 columns.
  • CC-B

  • CC-B is a subset of MicroPDF417 Symbol, which is identified by the Code 920. Encoding systems choose CC-B automatically when CC-A has not enough capacity than needed. CC-B encodes up to 338 digits of alphanumeric data in 3 to 12 rows and 2 to 4 columns.
  • CC-C

  • The CC-C structure is a PDF417 Symbol, which is clearly identified by the internal code word 920 (920 is the first code word after the symbol length indicator). The CC-C structure can be used as a 2 dimensional composite component of a UCC/EAN-128 Composite Symbols. It has the largest data capacity of EAN.UCC Composite Symbols because of its possibility to code of up to 2361 numbers. It can code numbers with up to 2361 digits of alphanumeric data, which have a minimum of 3 to 30 rows and up to 30 Data-Error-checking-Code-Columns.

    Benefits of RSS bar codes and CC-Composite Components:


  • The composite symbol is the only one with an easily scannable item identification.
  • The composite symbols are comparable in size to the matrix symbols but can be scanned with a wider range of scanner technologies.
  • The composite symbol combined with RSS is smaller than other laser scannable 2D symbols.
