IPDS uses variable size outline fonts, where the size of the HRI line is adapted to fit the size of the
bar code symbol.
Module width, resolution and device dependence
In the BCOCA architecture, the module width, i.e. the width of a narrow bar, is specified in mils
(1/1000”). In order to print all bar codes at their correct widths, you would need a printer with a
resolution of 1000 DPI. A 240, 300, or 600 DPI printer must always use approximate module
widths instead of the ideal, theoretical, values. Because of its low resolution, a 240 DPI printer
must represent four to six of the module widths in the application data, given in Mils, through a
single printed width. The module widths 12, 13, 14, 15, and 16 Mils will all be printed 12 Mils
wide. A 600 DPI printer can use smaller steps; the 13 and 14 Mil symbols have the same size, the
15 and 16 Mil symbols are larger. A 15 Mil DataMatrix symbol will therefore be 20% larger on a
new 600 DPI printer than on an old 240 DPI machine.
The general rule for the printer is to use the largest number of dots which fits into the ideal width
specified in the application. Printers may also choose to ignore very small Module Width values
and print a larger bar code symbol if the readability of the smaller symbol would be too poor.
Since bar codes are highly dependent of resolution and technology, you should always test the
BCOCA application on the actual target printer. In many cases you must adapt the application
when you move it to another machine.
