Barcode properties
This topic lists the properties of the barcode type Royal Mail 2D Mailmark. For the properties of
other barcode types, see "Barcode type and properties" on page196.
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:
l None: The barcode is rendered based on the module width.
l 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: ~~.
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.
