Symbologies

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.
