Royal Mail 2D Mailmark

Royal Mail 2D Mailmark 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 Royal Mail 2D Mailmark. For the properties of other barcode types, see Barcode type and properties.

Barcode properties

Module width

The recommendation is to print these barcodes with a module size of 0.5 mm, which equates to 6 dots when printed at 300dpi. The maximum module size for printing is 0.7 mm.

Preferred version

Use the drop-down to select the size of the barcode, in a number of modules. The actual size of the barcode can be 12 mm x 12 mm up to 22.4 mm x 22.4 mm, depending on the preferred version and the module width.

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.

  • Proportional: The barcode is stretched up to where it fits either the width or height of the parent box, whichever requires the less stretching.

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: ~~.

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.

  • PNG: Binary rasterized format. This has a slightly lower quality than SVG but is usually generated faster.
