Code 39 Settings

Code 39 is a discrete, self-checking barcode that is also known as "Alpha39", "Code 3 of 9" (often abbreviated to "3 of 9"), "Code 3/9", "Type 39", "USS Code 39" and "USD-3".

Code 39 data should contain no more than 20 digits from within the following range: Numeric digits: (0-9), upper-case letters (A-Z), seven special characters (- . space $ / + %) and the start/stop asterisk (*) character.

If the Extended character set is chosen, then lower-case letters (a-z) and other special ASCII characters can also be included.

To create dynamic barcodes, Metadata options must first have been set (see Metadata options). Metadata fields are required to create the association between the dynamic data used in the print run and the barcode.


Use the following options to configure the output Barcode settings:

  • General group:

    • Include in output checkbox: This determines whether of not this Additional Content entry should be included in the output or not.
      It is checked by default for all new entries.
      This option allow for "libraries" of Additional Content to be created in Presets, libraries from which you can pick and choose what entries you wish to have included, at time of printing.

    • Description edit box: An edit box for adding an optional Description to the Additional Content entry.

  • Position group:

    • Orientation: Use the drop-down to select the orientation of the Barcode added to the page.

    • Output once per sheet: This option relates to Imposition printing (see Imposition), also known as N-Up printing. Select this box to have the Barcode printed once per sheet rather than once per document page.

      If Imposition options such as auto-positioning and scaling were selected, these options won't apply to the Additional Content added to the physical N-Up sheet.

    • Left: Enter the distance between the left margin of the page and the Barcode, in either metric (cm/mm), inch (in) or point (pt) values.

    • Bottom: Enter the distance between the bottom margin of the page and the Barcode, in either metric (cm/mm), inch (in) or point (pt) values.

  • Code 39 Properties group:
    • Height: Enter the Barcode height in either metric (cm/mm), inch (in) or point (pt) values.
    • Use extended character set: Check to use the Code 39 Extended character set. This extends the range of supported data to include the full ASCII character set. This adds support for lower case letters (a-z) and the full range of ASCII punctuation and special characters.
    • Module Width: Specifies the width of the narrow bars. Changing this value to a higher value will generally make the Barcode bigger. The smallest Module Width is 0.19mm (high density).
    • Bar width ratio: Set the Barcode bar width.
      • Checksum: Use the drop-down to select how to deal with the Barcode checksum:

      • Ignore: Ignore checksum calculations.

      • Auto: Add a checksum character to the Barcode if the initial value does not validate. This is the default value.

      • Check: Verify the Barcode has a valid checksum.

      • Add: Calculate and add a checksum character to Barcode, regardless of current value.

      • Print human readable text: Check to add a textual version of the Barcode data.

      • Placement: Use the drop-down to select whether to place the human readable text above or below the Barcode.

      • Font name: Use the drop-down to select the font with which to display the human readable text.

        Vertically-oriented fonts (fonts whose typeface name begin with the at (@) character) are not supported in Connect.

      • Font size: Enter a font size for the human readable text.

  • Text: Enter the text used to generate the Barcode.

    •  Add button: Click to display a list of variable data that could be used for generating the Barcode.
      This includes metadata fields which must previously have been added in the Metadata options, likely at the Document Tags level (see Metadata Options), as well as some information fields.

  • Condition: Enter the condition which determines whether or not the Barcode will be added to the document at print time. For details on how to create a conditional, see How to Set Conditionals.

    •  Add button: Click to display a list of metadata fields, information fields to add, or common expressions to the condition.
