UPC/EAN Global Settings
This section provides configuration settings for UPC-A, UPC-E, EAN 13 and EAN 8
symbologies, and affects all of these unless otherwise marked for each feature description.
UPC/EAN 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 decoding 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.
