7.2 Calibration of your Scanner
using SilverFast IT8 Calibration
SilverFastAi for some high-end devices features a professional tool
for calibration and generation of input ICC profiles. The calibration
can be made for reflective and transparency positive originals. The
calibration is NOT applicable to negative originals.
The IT8 calibration is an additional function in the SilverFast soft-
ware. It is usually an option to the software and therefore has to be
activated separately. In certain SilverFast versions - for selected
scanners - this function is active by default. In cases where this
function must be activated separately, a second CD Rom is
required for this procedure - the "SilverFast Feature-CD".
The separate activation procedure is described in chapter
"SilverFast Feature-CD".
SilverFast has made the process of IT8 calibration very convenient
­ all steps are performed automatically by the software, just follow
the instructions outlined below.
1. Position the IT8 Reference Chart on your Scanner Bed.
Make sure that the original is positioned inside the scan area of
the scan bed. Avoid positioning on areas at the rim of the scan-
ner bed, with some scanners this areas must be kept clear for
hardware calibration. The orientation of the IT8 target should be
as shown on the left.
2. Click "Prescan" (the Scanner performs a Prescan).
3. Click the button "Calibration"
4. The Window "IT8 Calibration" pops up
The preview window and the grid will open.
