7.3 Decoding Parameters
Attention
These parameters are intended to enhance the
decoding capability of the reader for particular
applications. Used incorrectly, they can degrade the
reading performance or increase the possibility of a
decoding error.
7.3.1 Ink-Spread
The ink-spread parameter allows the decoding of codes which are not perfectly printed because the page
texture tends to absorb the ink.
7.3.2 Overflow Control
The overflow control parameter can be disabled when decoding codes printed on small surfaces, which don’t
allow the use of an overflow space.
This command does not effect code families 2/5, Code 128 and Code 93.
For the EAN/UPC code family, do not use code combinations. Each code must be selected singularly if this
control is disabled.
For example, to read EAN8 and EAN13 without overflow control select two codes: EAN8 and EAN13; do not
select the EAN8/EAN13 combination.
7.3.3 Interdigit Control
The interdigit control parameter verifies the interdigit spacing for code families Code 39 and Codabar.
