GS1-128

GS1-128 is one of the types of barcodes that can be added to a template; see Barcode.

The barcode can be added either using the Barcode toolbar button or through selecting Insert > Barcode on the menu; see Adding a barcode.

To change a barcode's properties, such as the scale and color, open the Barcode properties dialog: right-click the barcode (on the Design tab in the Workspace) and select the Barcode... option in the context menu.

This topic lists the properties and output options of the barcode type GS1-128. For the properties of other barcode types, see Barcode type and properties.

Barcode properties

Module width

Specifies the width of the narrow bars in centimeters. Changing this value to a higher value will make the barcode bigger when Scale is set to None.

Scale

Defines if and how the rendered barcode is scaled in relation to the parent element:

  • None: The barcode is rendered based on the module width.

  • Fit to box: The barcode is stretched to fit the parent box in both width and height.

Add Checksum

When checked, PlanetPress Connect will calculate a Checksum character and add that to the result of the Barcode script. If the value to be encoded is longer than 10 digits, a second check character will be calculated.

Tilde processing

Check this option to process tilde (~) characters in the data as special characters. (See the Java4less Barcodes Guide to learn what the tilde character can be used for.)
The tilde is expected to be followed by the 'd' character and 3 digits representing an ASCII character: ~dNNN . For example, ~d013 represents a carriage return.
Note that with this option checked, any tilde that needs to be included in the output must be escaped by adding another tilde: ~~.

Human Readable Message

When this option is checked, PlanetPress Connect shows a human readable text below or above the barcode, as defined using the Text Position, using the specified font and font size. The font size is given in points (pt).

Barcode output

Color

The Color group allows you to choose a different Barcode color (instead of black) and Background color (instead of white), by typing a hexadecimal color value (see for example w3school's color picker).

When black is a composite of CMYK or RGB values, it may incur a color click charge on some printers. Check the Output in Grayscale option to make sure that pure black is used.

Output format

Defines how the barcode is output on the page. There are two possible formats:

  • SVG: Vector format. This is usually of higher quality, but may take longer to generate and is not compatible with Email output.

  • PNG: Binary rasterized format. This has a slightly lower quality than SVG but is usually generated faster and will display properly in Email output.
