VRS User’s Manual
For example, suppose you select 300 DPI in your scanning application and enable the
first level of Accelerated Scanning in VRS. The image scans at 200 DPI to accelerate
scanning speed and VRS translates it to 300 DPI to achieve the desired resolution.
Table 3-6 lists the DPI settings that VRS uses for a typical scanner. Use this table as an
example of how VRS treats DPI settings defined in a scanning application.
Note
When you select the first level of accelerated scanning, the image quality is
virtually equivalent to non-accelerated scanning. However, higher levels of
acceleration affect the image quality. Not all scanners increase in speed when you
select accelerated scanning. If your scanner does not offer lower resolutions than the
resolution selected in your scanning application, accelerated scanning will have no
effect.
