Width of bar and space •
NB (narrow bar) is standard. If you require a different bar width and space refer to the
following specifications:

0.165 < 0.2 mm NB to 1.25NB 2.2NB to 3.0NB 2.2NB to 3.0NB NB to 3.0NB
If a high print contrast signal value is obtained by printing a barcode clearly on a label with a
high reflection factor and if the width of bars and spaces are retained as follows, the narrow
barcode can be used only for NW7.

0.130 - 0.156mm 0.216 - 0.238mm 0.401 - 0.413mm 0.465 - 0.492 0.465 - 0.492mm
Caution
It is recommended to use bars and spaces of 2.5 NB or more so that WB (wide bar), WS (side space),
and G (gap) can be identified easily. If less than 0.2 mm of NB (narrow bar) is used, it is recommended
to use the barcode check character to retain the reliability of the barcode read.
