The SW and PA both scan documents at up to 600 dpi in 8-bit grayscale with a user selectable
illumination source of
Near IR
or
RGB / Visible light
. The default configuration of the scanner
is to use RGB / Visible light illumination since this setting works for a large percentage of
document types. However, many travel documents have a background printed in RGB and
OCBR symbology printed with carbon based ink which resonates in near IR wavelength;
therefore, it is recommended that the scanner be configured for IR illumination (see below) when
processing these document types.
17.1 Scanner Settings
Listed below are the user configurable scanner settings. These
configuration options can be adjusted programmatically by calling API
functions or by using a Datastrip supplied sample application such as
DsVerifyScanTestAsync.exe
which
is located in the \Storage
Card\DSVII directory.
RGB Scanner Settings:
From the menu select “Scanner” and then select “Scanner settings…”
•
Make sure the “IR” box is unchecked
•
Set Intensity=50%.
•
Leave all the other settings as default
