Code 11 Decoding Level
Decoding Levels are used to configure a barcode symbology decoder to be very aggressive
to very conservative depending on a particular customer’s needs.
Choosing Level 1 results in a very conservative decoder at the expense of not being
able to read poorly printed or damaged labels.
Choosing Level 5 results in a very aggressive decoder. This aggressive behavior
allows decoding of poorly printed and damaged labels at the expense of increasing
the likelihood of decoding errors.
Choosing Level 3, which is the default setting, allows the majority of product
labels to be decoded.
There are many factors that determine when to change the decoding level for a particular
symbology. These factors include spots, voids, non-uniform bar/space widths, damaged
labels, etc. that may be experienced in some barcode labels. If there are many hard to read
or damaged labels that cannot be decoded using a conservative setting, increase the de-
coding level to be more aggressive. If the majority of labels are very good quality labels,
or there is a need to decrease the possibility of a decoder error, lower the decoding level
to a more conservative level.
