Scanner Options
5.3.1 Patchcodes
With the "Patchcodes" tab several settings can be adjusted concerning the search for Patchcodes.
The search can be restricted to the front or rear side of a document, or to a specific search area on
the page. In addition, the quality level can be adjusted to look for thinner or thicker Patchcodes, or to
report an error if a code could not be identified exactly.
Search Patchcodes on
front / rear side
Enabling this option turns on the search separately for the front and rear
side.
If you disable the search, Patchcode dependent rules will not be
available.
Interference Reduction
This filter reduces white pixels from the black area of a Patchcode bar.
Noise like this can result from the scanner itself after retreatment of an
image by the IP hardware.
Detect thicker / thinner
Patchcodes
Patchcodes are defined with fixed sizes. To detect Patchcodes varying
the slightest bit from this size, one can choose this checkbox.
Stop on Error
With this option enabled, the scanner stops when a Patchcode cannot be
identified exactly.
Position and Size of
the Search Area
If the Patchcode bar is not printed over the whole page, but only in a
specific area, a search area can be defined.
With the means of these parameters, the location and the size of the
search area can be defined.
The values are given in 0.1 mm increments.
Please note that the upper border of the search area cannot be specified
because the upper border is always the top of the sheet.
As a general rule of thumb, the Patchcode should be recognized as
soon as possible; that means it should be printed at the upper edge
of a sheet (in direction of transport).
